• The blank/black Modules page in ABP Suite is typically caused by a failed backend call that returns an unexpected payload. In your screenshot, the frontend throws “Cannot read properties of undefined (reading 'id')”, which is consistent with the Modules API returning an error/empty response and the UI not handling it properly.
• The most common reason (and it directly matches the “can’t download module source code” symptom) is that Suite cannot access ABP Commercial source download endpoints due to an invalid/expired CLI login token (or a license/auth failure). When that happens, Suite’s backend download calls fail (often with 403 Forbidden), and the Modules UI can end up blank.

Fix (works for both “Modules page is blank” and “can’t download pro module source code” cases):

1. Close ABP Suite / ABP Studio (all instances).
2. In a terminal, run:

abp logout
   abp login

3. Start Suite again:

abp suite

4. Go to Modules and try downloading the module source again.

If you’re on the Business plan and still can’t download Elsa module source

• This becomes a license/entitlement issue (plan may not include that module’s source code, or the account/license assigned to your login may not have access). In that case you need Volosoft to check your subscription entitlements and your account.

• In ABP MVC (v10.3), the recommended approach is the same as plain ASP.NET Core MVC: return HTML from a server endpoint and inject it into the DOM. The “ABP part” is mainly:
  • keep your UI logic in ViewComponents (they are already the ABP convention for reusable UI blocks),
  • use ABP’s standard MVC patterns (anti-forgery, localization, theming, layout hooks where relevant).

1) Create a “dynamic component host” endpoint

Create a regular MVC controller action that decides (at runtime) which ViewComponent to render, then returns the ViewComponent result.

using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc;

public class DynamicComponentController : AbpController
{
    [HttpGet]
    public IActionResult Render(string component, string id)
    {
        // Decide at runtime (example mapping/whitelist)
        // IMPORTANT: whitelist allowed components, do NOT allow arbitrary type names from the client.
        var allowed = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase)
        {
            ["OrderSummary"] = "OrderSummary",   // VC name
            ["CustomerCard"] = "CustomerCard"
        };

        if (!allowed.TryGetValue(component, out var viewComponentName))
        {
            return BadRequest("Unknown component.");
        }

        // Pass parameters to the VC (anonymous object becomes arguments)
        return ViewComponent(viewComponentName, new { id });
    }
}

This lets you call /DynamicComponent/Render?component=OrderSummary&id=123 from AJAX and receive ready-to-insert HTML.

2) Implement your ViewComponents the ABP way

ABP’s AbpViewComponent is the typical base class.

using Microsoft.AspNetCore.Mvc;
using Volo.Abp.AspNetCore.Mvc;

public class OrderSummaryViewComponent : AbpViewComponent
{
    public IViewComponentResult Invoke(string id)
    {
        // load model, build view model, etc.
        return View("~/Components/OrderSummary/Default.cshtml", model: id);
    }
}

3) Fetch via AJAX and inject HTML

Example with fetch:

<div id="dynamic-area"></div>

<script>
async function loadComponent(component, id) {
  const url = `/DynamicComponent/Render?component=${encodeURIComponent(component)}&id=${encodeURIComponent(id)}`;
  const resp = await fetch(url, { headers: { "X-Requested-With": "XMLHttpRequest" }});
  const html = await resp.text();
  document.getElementById("dynamic-area").innerHTML = html;
}
</script>

4) Key security + maintainability notes (important)

• Do not accept arbitrary type names from the client and Type.GetType(...) them. Always use a server-side whitelist/mapping (as shown).
• If your endpoint is POST, ensure anti-forgery is handled (ABP integrates ASP.NET Core anti-forgery).
• If the component requires scripts/styles, prefer:
  • returning a partial that already includes needed markup, or
  • using ABP bundling/layout hooks for global assets (when appropriate).

• What you did (Object Extension + EF Core mapping) only extends the entity and database schema. It does not automatically extend the Payment module’s MVC UI (datatable columns, create/edit forms, etc.).

• The reason your IdentityUser extension shows up in the UI is that Identity module’s UI is integrated with the “module entity extension” UI system (ABP Commercial feature). The Payment module’s “Payment Requests” UI does not automatically render arbitrary extension properties as extra columns.

• So you are not missing an EF mapping step. You need to extend/customize the MVC UI of the Payment module explicitly.

• Overriding the entire page source:

  • The Payment module’s MVC UI pages come from the module’s Razor Pages via the Virtual File System (embedded resources). Overriding them is possible, but it’s not exposed as a simple “download page source” feature.
  • Practically, you either:
    1. add a UI extension point (if that page supports it), or
    2. copy the related Razor Page(s) from the module source code and override via VFS, or
    3. build your own page that lists payment requests including your new column.

• Since this is a PRO/commercial module UI customization, and I can’t reliably fetch/verify the Payment module page source or the exact supported UI extension points right now (tooling access issue), the safest, verified next step is to contact ABP support so they can point you to the exact page/extension-point for “Payment Requests” in v10.0.3 MVC:

• Avoid “dynamic table name” access through EF Core repositories. In ABP (and EF Core), a repository is designed around a fixed entity mapping. Switching the underlying table name at runtime typically pushes you outside of EF Core’s normal model mapping and can easily bypass ABP’s cross-cutting features (unit of work boundaries, data filters like soft-delete/multi-tenancy, auditing, etc.) unless you re-implement them carefully.

• Recommended approach (still repository-based): model the dynamic tables explicitly, then select the repository/service at runtime.

  1. Create a separate DbSet<TEntityX> + mapping for each target table (per template/table).
  2. Create a repository/app service per entity/table.
  3. At runtime (based on the chosen template), route to the correct service/repository (your “dictionary of delegates” idea fits here, but you delegate to typed repositories rather than returning raw table names).

• If you truly have “same schema, multiple tables” (e.g., PresentationData_1, PresentationData_2, ...), EF Core has a concept that ABP can support in advanced scenarios via the repository’s EntityName (meant for EF Core shared-type entity types). You’d configure multiple named entity mappings in your DbContext and then choose which mapping to use by setting the repository’s entity name before executing operations.

public class MyAppService : ApplicationService
  {
      private readonly IRepository<PresentationRow, Guid> _repo;

      public MyAppService(IRepository<PresentationRow, Guid> repo)
      {
          _repo = repo;
      }

      public async Task<List<PresentationRow>> GetRowsAsync(string templateKey)
      {
          _repo.SetEntityName(templateKey); // selects the named mapping configured in EF Core model
          return await _repo.GetListAsync();
      }
  }

This keeps you in the repository/UoW world, but requires correct EF Core model configuration for each named mapping.

• When direct table access is acceptable in ABP: If the data is not part of your domain model (purely “reporting / template rendering / denormalized read model”), consider implementing a dedicated Dapper-based or raw SQL query service in the Infrastructure layer and keep it read-only. Then you still benefit from ABP’s Unit of Work by ensuring the method runs inside a UoW (default in app services), while not trying to force dynamic tables into EF Core entity mapping.

• What I would not advise: building SQL by concatenating table names from user input. If you must choose a table dynamically, only allow it from a strict whitelist (your dictionary) and keep the SQL parameterized for values.

• Add a physical LastName column to AbpUsers (IdentityUser)
  1. Define the extension property in your *.Domain.Shared project (YourProjectNameModuleExtensionConfigurator.cs), inside ConfigureExtraProperties:

using System.ComponentModel.DataAnnotations;
     using Volo.Abp.ObjectExtending;

     ObjectExtensionManager.Instance.Modules().ConfigureIdentity(identity =>
     {
         identity.ConfigureUser(user =>
         {
             user.AddOrUpdateProperty<string>(
                 "LastName",
                 options =>
                 {
                     options.Attributes.Add(new StringLengthAttribute(64));
                 }
             );
         });
     });

2. Map it to a real SQL column in your *.EntityFrameworkCore project (YourProjectNameEfCoreEntityExtensionMappings.cs):

using Volo.Abp.Identity;
     using Volo.Abp.ObjectExtending;

     ObjectExtensionManager.Instance
         .MapEfCoreProperty<IdentityUser, string>(
             "LastName",
             (_, propertyBuilder) =>
             {
                 propertyBuilder.HasMaxLength(64);
                 propertyBuilder.HasDefaultValue("");
             }
         );

3. Add migration + update DB (run from the migrations/EFCore project you use):
   • Add-Migration Added_LastName_To_AbpUsers
   • Run DbMigrator / Update-Database

• Show Surname as “Middle Name” only on the UI

  • Don’t change the backend property name (Surname) if you want to keep ABP’s defaults; just change the label/display text in the registration UI.
  • In MVC/Razor Pages, the “label text” is typically localized; you can override the localization value for the displayed field name (so it renders as Middle Name while still posting to Surname).

• Make the registration page order: Name, Middle Name (Surname), Last Name

  • In MVC, the reliable way is to override/customize the Register page UI and reorder the inputs in the .cshtml.
  • Keep binding as:
    • Name → first input
    • Surname → second input (but label it “Middle Name”)
    • ExtraProperties["LastName"] (or your strongly typed extension) → third input

• If you want LastName to be saved during registration

  • Add the input on the register form and send it as an extension property.
  • In tiered solutions, ensure the Account endpoints can carry your extension property by applying entity configuration to the Account/Profile/Register DTOs (same mechanism used for profile update). The known working approach is to call ModuleExtensionConfigurationHelper.ApplyEntityConfigurationToApi(...) in the host where the Account endpoints run (AuthServer/HttpApi.Host), including the relevant DTO types.

• Install the ABP imaging provider + ASP.NET Core integration in your HttpApi.Host (or where your upload endpoint lives):

abp add-package Volo.Abp.Imaging.ImageSharp
abp add-package Volo.Abp.Imaging.AspNetCore

• Create a typed blob container to store the processed image:

using Volo.Abp.BlobStoring;

namespace MyCompany.MyProject;

[BlobContainerName("user-images")]
public class UserImageContainer
{
}

• Create an upload controller action and use ABP’s attributes to compress and resize automatically:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System.Threading.Tasks;
using Volo.Abp.BlobStoring;
using Volo.Abp.Imaging;

namespace MyCompany.MyProject.Controllers;

[Controller]
[Route("api/image")]
public class ImageController : ControllerBase
{
    private readonly IBlobContainer<UserImageContainer> _blobContainer;

    public ImageController(IBlobContainer<UserImageContainer> blobContainer)
    {
        _blobContainer = blobContainer;
    }

    [HttpPost("upload")]
    [CompressImage]
    [ResizeImage(width: 200, height: 200)]
    public async Task<IActionResult> UploadAsync(IFormFile file)
    {
        var fileBytes = await file.GetAllBytesAsync(); // ABP extension method
        await _blobContainer.SaveAsync(file.FileName, fileBytes, overrideExisting: true);
        return Ok();
    }
}

• (Optional) Endpoint to return the stored bytes:

[HttpGet("{fileName}")]
public async Task<byte[]> GetAsync(string fileName)
{
    return await _blobContainer.GetAllBytesAsync(fileName);
}

• For www.website.com/@handle (path-based) the cleanest approach in ABP is to treat the handle as a route segment and then (optionally) adjust PathBase so that link generation works correctly across the UI—exactly the same pattern ABP uses for “tenant in the route”.
• For handle@www.website.com (subdomain / host-based) this is not valid DNS/URL syntax (the @ is not a host label separator). If you meant handle.website.com, that’s host-based routing and should be implemented via subdomains (and optionally ABP’s domain-based tenant resolution). The rest of this answer focuses on the working pattern: /{handle} or /@{handle}.

1) Path-based handle: /{handle} or /@{handle}

Step 1 — Add a middleware that detects /@handle and moves it into PathBase

This preserves ABP’s routing and also makes relative URLs/navigation work (because the app “thinks” it’s hosted under /@handle).

Put this before app.UseRouting() in your Web/HttpApi.Host OnApplicationInitialization:

using System.Text.RegularExpressions;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;

public override void OnApplicationInitialization(ApplicationInitializationContext context)
{
    var app = context.GetApplicationBuilder();

    app.Use(async (httpContext, next) =>
    {
        // Matches: /@john or /@john/...  (handle chars: letters, numbers, underscore, dot, dash)
        var match = Regex.Match(httpContext.Request.Path, @"^/@([a-zA-Z0-9_.-]+)(?:/.*)?$");
        if (match.Success)
        {
            var handle = match.Groups[1].Value;

            // OPTIONAL: validate handle exists (recommended)
            // var handleStore = httpContext.RequestServices.GetRequiredService<IUserHandleStore>();
            // if (await handleStore.ExistsAsync(handle))
            {
                if (httpContext.Request.Path.StartsWithSegments(new PathString("/@" + handle),
                        out var matchedPath,
                        out var remainingPath))
                {
                    var originalPath = httpContext.Request.Path;
                    var originalPathBase = httpContext.Request.PathBase;

                    httpContext.Request.Path = remainingPath;
                    httpContext.Request.PathBase = originalPathBase.Add(matchedPath);

                    try
                    {
                        await next();
                    }
                    finally
                    {
                        httpContext.Request.Path = originalPath;
                        httpContext.Request.PathBase = originalPathBase;
                    }
                    return;
                }
            }
        }

        await next();
    });

    app.UseRouting();
    // ...
}

What this gives you:

• Request /@john/posts/42 is internally rewritten to:
  • PathBase = "/@john"
  • Path = "/posts/42"
• Your controllers/pages can keep “normal” routes (/posts/{id}), while the UI still works under the handle prefix.

Step 2 — Make the handle available to your app code

A simple approach is to read it from HttpContext.Request.PathBase:

public static class HandleHttpContextExtensions
{
    public static string? GetHandleFromPathBase(this HttpContext httpContext)
    {
        var pb = httpContext.Request.PathBase.Value; // e.g. "/@john"
        if (string.IsNullOrWhiteSpace(pb)) return null;
        return pb.StartsWith("/@") ? pb.Substring(2) : null;
    }
}

Then in a controller/page/app service (via IHttpContextAccessor) you can resolve the “current private site owner” and load data accordingly.

Step 3 — Routing endpoints remain standard

You do not need special ABP routing features for this. Keep your normal endpoints, e.g.:

[Route("posts")]
public class PostsController : AbpController
{
    [HttpGet("{id}")]
    public IActionResult Get(int id) => Ok();
}

2) ABP-specific “best practice” angle

• The middleware + PathBase technique is proven in ABP for multi-tenancy “tenant in route” scenarios (it avoids broken navigation links and incorrect base paths).
• If your “private site” is conceptually similar to multi-tenancy (each handle is an isolated site), you can even model it like a tenant resolution strategy (route/domain contributors). Otherwise, keep it as a custom “handle resolution” abstraction.

3) Sources

• https://abp.io/community/articles/ah7oru97 (shows the same PathBase middleware pattern used for route-based resolution in ABP)
• https://docs.abp.io/en/abp/latest/Multi-Tenancy (ABP’s official multi-tenancy resolution concepts; useful if you decide to model handles similarly)

• ABP v10.3 already has built-in image compression & resizing support via the Image Manipulation infrastructure. Out of the box it integrates with ImageSharp and Magick.NET providers, and the system is extensible (you can plug in your own contributor/provider if you need a different library or a custom pipeline).
• For storing user-supplied images in a tiered solution, the recommended ABP approach is:
  1. Upload to your HttpApi.Host (backend) as IFormFile
  2. Run image processing (compress/resize, and any custom operations you add)
  3. Store results in ABP Blob Storing (DB, Azure Blob, S3, MinIO, etc.)
  4. Serve the processed image back to MVC UI (or via a CDN / direct object storage link if that’s your setup)

What ABP supports well (for your use-cases)

1) Compression / resize (supported directly)

1. Add an imaging provider package (commonly ImageSharp) to your backend (*.HttpApi.Host or *.HttpApi depending on your structure).
2. Optionally add the ASP.NET Core integration package to use action attributes.
3. Use ABP’s attributes on upload endpoints:
   • [CompressImage]
   • [ResizeImage(width, height)]

This lets you implement “upload → auto compress/resize → save” with minimal code.

2) Background removal and “place on a canvas” (not built-in, but integrates cleanly)

ABP does not provide a first-party background removal / segmentation feature. However, ABP’s modularity + DI makes third-party integration straightforward:

• If background removal is done by:
  • a .NET library: wrap it in an application service (or domain service) and inject it where you handle uploads.
  • an external API (e.g., a ML service): wrap the HTTP client in a service, configure via IOptions, and call it from your upload/application service.
• After background removal, “place on a canvas” is typically just another imaging step (compose layers, resize, encode). You can do it:
  • server-side (recommended for consistency and security), then store via Blob Storing
  • or client-side (HTML canvas) and upload the final result back—ABP doesn’t restrict this, but server-side is usually easier to govern.

3) Where to implement the processing (recommended layering)

• Put the upload endpoint in HttpApi.Host (tiered backend).
• Put the processing orchestration in an Application Service (so it’s reusable and testable).
• Use Blob Storing to persist originals and/or derivatives (thumb, preview, final).

A typical flow:

• Save original (optional)
• Produce derivatives:
  • compressed original
  • resized thumbnails
  • background-removed PNG
  • final “canvas composed” output
• Save each to its own blob name (or separate containers)

Third-party tool integration guidance (ABP-specific)

• ABP is just ASP.NET Core under the hood: any third-party .NET library (ImageSharp extensions, OpenCV wrappers, ML.NET, etc.) can be registered in DI and used normally.
• If your processing is heavy, ABP also supports doing this asynchronously via background jobs (not required, but commonly used). If you go that route, store the upload first (Blob Storing), enqueue a job, and generate derivatives in the background.

• For “run at night, every day, for any timezone”, use an ABP Background Worker with the Quartz integration (cron scheduling + persistence). A “Background Job” in ABP is mainly for one-time / fire-and-forget work items; your case is a recurring schedule.
• Make the image processing itself idempotent and chunked:
  • Don’t process the same original image repeatedly: store a “retina generated” flag/version (or hash) in your DB.
  • If you have many images, process in batches/pages to avoid long transactions and memory pressure.
• Recommended architecture for your scenario:
  1. Store original images in a durable store (e.g., Blob storage / file system) and keep metadata in DB (original size, last-processed time, hash, etc.).
  2. A nightly Quartz worker finds “images needing retina versions” and generates the 2x versions.
  3. Save the retina outputs back to storage and update metadata.
• Timezone advice (so it works “at night time for any timezone”):
  • Best practice: schedule the worker to run frequently (e.g., every 15–60 minutes) and have it process only tenants/users whose local time is currently within your nightly window (e.g., 01:00–04:00). This avoids trying to create one cron trigger per timezone and keeps scheduling simple and robust.
  • Persist each tenant’s desired timezone (IANA/Windows) and “night window” in your settings table; compute “now in tenant timezone” inside the worker, then decide whether to process.
• Operational advice before you start:
  • Use persistent Quartz storage (SQL Server) so schedules survive restarts/deployments.
  • Add concurrency protections (e.g., prevent overlapping runs) and consider misfire behavior (what happens if the app was down at the scheduled time).
  • Add logging/metrics around: number of images scanned, processed, failed; duration; retry counts.
  • Keep the actual image resize code in a domain/application service; the worker should orchestrate only.

Minimal Quartz worker skeleton (ABP style)

using Quartz;
using Volo.Abp.BackgroundWorkers.Quartz;

public class RetinaImageNightlyWorker : QuartzBackgroundWorkerBase
{
    public RetinaImageNightlyWorker()
    {
        JobDetail = JobBuilder.Create<RetinaImageNightlyWorker>()
            .WithIdentity(nameof(RetinaImageNightlyWorker))
            .Build();

        // Example: run every 30 minutes (then decide per-tenant “is it night?” inside Execute)
        Trigger = TriggerBuilder.Create()
            .WithIdentity(nameof(RetinaImageNightlyWorker))
            .WithCronSchedule("0 0/30 * * * ?")
            .Build();

        ScheduleJob = async scheduler =>
        {
            if (!await scheduler.CheckExists(JobDetail.Key))
            {
                await scheduler.ScheduleJob(JobDetail, Trigger);
            }
        };
    }

    public override async Task Execute(IJobExecutionContext context)
    {
        // Resolve your app/domain service(s) and:
        // 1) iterate tenants
        // 2) if tenant local time is within night window => process a batch of images
    }
}
