  • ABP does not provide a built-in “transparent encryption” module for Blob Storing providers (S3/MinIO) or a built-in field-level encryption feature for EF Core entities that automatically encrypts/decrypts selected columns.
  • What ABP does provide (and you can safely build on) is:
    • IStringEncryptionService for encrypting/decrypting strings (ABP implementation uses AES; documented as AES/CBC) and configuration via AbpStringEncryptionOptions.
    • ASP.NET Core Data Protection APIs (usable in ABP like any ASP.NET Core app) for application-level data protection (cookies, tokens, etc.).

Issue 1 — Encrypting XML files stored in S3/MinIO (ABP Blob Storing)

Recommended ABP-style approach (application-level envelope encryption)

  1. Generate a per-file DEK (data encryption key) (random 256-bit).
  2. Encrypt the XML with AES (prefer AEAD like AES-GCM in your own implementation; ABP’s IStringEncryptionService is AES/CBC and string-focused).
  3. Store the encrypted file bytes in S3/MinIO using ABP Blob Storing as usual.
  4. Encrypt (“wrap”) the DEK with a master key managed outside the app (KMS/HSM/Vault), and store the wrapped DEK + metadata (algorithm, key id, version) alongside the blob (e.g., blob metadata or a DB table).

Where to plug this in ABP

  • Keep ABP Blob Storing provider (MinIO/S3) unchanged.
  • Implement a small service layer such as IEncryptedBlobStore that:
    • Takes a stream/bytes
    • Encrypts + uploads through ABP IBlobContainer
    • Downloads + decrypts on read

This avoids forking ABP Blob Storing and keeps encryption logic isolated.

Performance flow (streaming)

  • Upload: stream XML → encrypt stream on-the-fly → upload encrypted stream to MinIO.
  • Download: download encrypted stream → decrypt stream on-the-fly → consume plaintext stream.
  • Avoid loading full XML into memory; use streaming crypto.

Algorithms

  • ABP’s documented string encryption is AES (CBC) via IStringEncryptionService, but for file encryption best practice is AEAD (e.g., AES-GCM) with a random nonce per object + authentication tag. (ABP does not ship a file-encryption abstraction; you implement this with .NET cryptography.)

Key management / rotation

  • ABP itself doesn’t provide centralized KMS. Typical production pattern:
  • Master key in external KMS/HSM/Vault (never in appsettings).
  • DEKs are generated per file (or per tenant/bucket partition) and wrapped by KMS.
  • Rotation: rotate master key in KMS; re-wrap DEKs lazily or via background job.

Issue 2 — Field-level encryption in PostgreSQL (EF Core)

ABP support mechanisms

  • ABP does not have a built-in “encrypt these entity properties” feature.
  • ABP does provide IStringEncryptionService which you can use to implement field encryption yourself (e.g., EF Core ValueConverter, or domain setters/getters).

Practical implementation pattern (EF Core ValueConverter)

  • Create a ValueConverter<string,string> that uses IStringEncryptionService.Encrypt/Decrypt.
  • Apply it to sensitive properties in OnModelCreating.

Important operational consequence:

  • Queries/search: encrypted columns are generally not searchable by plaintext criteria (e.g., Where(x => x.NationalId == "…")) unless you:
    • search by an additional deterministic index (e.g., keyed hash column), or
    • use database-native encryption/search approaches. ABP doesn’t provide built-in tokenization/searchable encryption.

Tokenization vs encryption in ABP

  • ABP has no built-in tokenization feature for domain data.
  • ABP’s provided primitive here is string encryption (IStringEncryptionService, AES-based) and ASP.NET Core data protection; anything beyond that (token vault, format-preserving tokenization, searchable encryption) is custom/external.

Key management for DB encryption

  • Same as files: keep master keys outside the app (KMS/Vault/etc.).
  • ABP’s AbpStringEncryptionOptions requires consistent parameters across instances; you should load secrets from a centralized secret manager (example ABP community article shows AWS Secrets Manager integration).

  • This looks like an ABP Studio 3.0.3 UI crash while it is trying to refresh the Kubernetes/Helm chart tree after you add the second Web module (apps -> Add -> New Module -> Web). The stack trace is inside ABP Studio (HelmSubChartItemViewModel, ChartUIModel.RefreshSubChartsAsync), not in your solution code, and it typically happens when Studio expects a Helm subchart metadata object but it is missing/null for the newly added app.

  • Workaround (recommended): manually create the Helm subchart for the new web app, then refresh charts.

    1. Open your solution’s main Helm chart folder (the one that contains a Chart.yaml and a charts/ directory) in VS Code.
    2. Under the charts/ folder, create a new folder for your new web app (e.g. tenant-web/).
    3. Copy an existing working web subchart folder (e.g. the one created for TenantAdminWeb) as a template, and update its metadata/values to match the new app (image name, project path, etc.).
    4. Go back to ABP Studio and on the main chart, run Refresh Sub Charts.

    This aligns with ABP Studio’s documented flow: when you add a microservice/module, you should also create its subchart, then refresh subcharts so Studio can load them properly.

  • Practical mitigation if you don’t need Kubernetes integration right now:

    • Disable/avoid using the Kubernetes/Charts view in Studio for this solution until you’ve created the missing subcharts (the crash is triggered during chart refresh/loading).
  • If you want this fixed in Studio rather than working around it:

    • This is an ABP Studio product bug (NullReference during chart/subchart loading). Please report it to Volosoft via the official contact channel and include your stack trace + the exact “new module” names you used and that Kubernetes config is enabled.

  • AutoMapper / Scriban package updates (vulnerabilities):

    • ABP regularly upgrades its NuGet dependencies to newer versions as part of its release cycle. There isn’t a separate public “ETA” per-package that I can confirm from the available verified sources.
    • What I can verify from ABP support history is that the team’s approach is to upgrade NuGet packages to the latest and that such upgrades are handled via PRs/regular releases (example answer from ABP team): see the source below.
  • VS 2026 stopping EF migration generation / DB update regardless of ErrorActionPreference:

    • I don’t have a verified ABP-specific source/known issue entry for this Visual Studio 2026 behavior from the available context.
    • This sounds like a change in Visual Studio / PowerShell tooling behavior (outside ABP), rather than an ABP framework feature toggle, but I can’t provide a definitive ABP-verified fix without a verified source.
  • Actionable guidance you can safely apply in ABP solutions:

    1. Keep ABP packages on the latest patch/minor for your major line (e.g., 8.3.x → latest 8.3.*) since ABP dependency updates typically ship via ABP releases.
    2. If your security scanner flags transitive vulnerabilities, you can usually mitigate by:
      • upgrading ABP to a newer version that carries updated transitive dependencies, and/or
      • adding a direct PackageReference override (if compatible) in your solution (this is standard NuGet behavior; test thoroughly).

  • Yes, this behavior is a known type of UI refresh/layout issue in Angular apps where the table is rendered before its container gets a final size (e.g., after route animation/layout calculations). A window resize triggers a reflow, so the datatable suddenly paints correctly. The same reason explains why clicking sort sometimes doesn’t redraw until resize.

  • In ABP Angular UIs, a practical workaround is to force a resize/reflow after the data arrives / after view init on the Users/Roles pages (or globally after navigation).

Workaround (Angular)

Add a small resize dispatch after the list loads or after the view is stable:

import { AfterViewInit, Component, NgZone } from '@angular/core';

@Component({...})
export class UsersComponent implements AfterViewInit {
  constructor(private zone: NgZone) {}

  ngAfterViewInit() {
    // Let Angular finish rendering, then trigger a reflow for the datatable
    this.zone.runOutsideAngular(() => {
      setTimeout(() => window.dispatchEvent(new Event('resize')), 0);
      setTimeout(() => window.dispatchEvent(new Event('resize')), 100);
    });
  }
}

If you don’t want to touch module pages, you can do something similar once globally after each navigation ends (e.g., in your root layout component subscribing to Router events) and dispatch a resize.

Recommended fix

  • Upgrade to the latest patch/minor version in the 9.x line (or newer) on both backend and Angular packages. These kinds of UI issues are typically addressed in later patch releases, and staying on 9.1.2 can keep you exposed to already-fixed frontend quirks.

1. Solution

This behavior is consistent with the DTO mapping not copying ExtraProperties from Volo.Saas.Tenants.Tenant to SaasTenantDto in the SaaS Host tenant listing flow.

In ABP, extension properties stored in JSON (ExtraProperties) are not automatically included in outgoing DTOs unless the application service maps them (for security reasons). The usual/conventional way is to call MapExtraPropertiesTo(...) while mapping entity → DTO (or enable/configure MapExtraProperties in the object mapper profile).

So, even if:

  • the entity has ExtraProperties["TaxNumber"] = "12345678"
  • the UI column is generated from the extension definition (so the header appears)

…the grid cells will remain empty if the returned SaasTenantDto.ExtraProperties doesn’t contain that value.

Recommended fix (JSON-only; no MapEfCoreProperty required): override/replace the SaaS tenant app service and map extra properties to the DTO in GetListAsync (and other relevant methods).

Example (replace the built-in service):

using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Volo.Abp;
using Volo.Abp.Application.Dtos;
using Volo.Abp.DependencyInjection;
using Volo.Saas.Host;
using Volo.Saas.Tenants;

namespace MyCompany.MyProject.Saas;

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(ITenantAppService), typeof(TenantAppService))]
public class MyTenantAppService : TenantAppService
{
    public MyTenantAppService(
        ITenantRepository tenantRepository,
        TenantManager tenantManager)
        : base(tenantRepository, tenantManager)
    {
    }

    public override async Task<PagedResultDto<SaasTenantDto>> GetListAsync(GetTenantsInput input)
    {
        var result = await base.GetListAsync(input);

        // Ensure extra properties are present in the DTOs so UI can render them
        // (TaxNumber, etc.)
        foreach (var item in result.Items)
        {
            // Nothing to do if already mapped by base implementation.
            // If empty, you must map from entity to dto at mapping time.
        }

        return result;
    }
}

However, to actually map from entity → DTO, you need access to the source entities at mapping time. The cleanest approach is to override mapping method if exists, or reimplement GetListAsync by querying entities and mapping yourself, explicitly calling MapExtraPropertiesTo:

using System.Linq;
using Volo.Abp.ObjectExtending;

public override async Task<PagedResultDto<SaasTenantDto>> GetListAsync(GetTenantsInput input)
{
    var totalCount = await TenantRepository.GetCountAsync(input.Filter);
    var tenants = await TenantRepository.GetListAsync(
        input.Sorting,
        input.MaxResultCount,
        input.SkipCount,
        input.Filter
    );

    var dtos = tenants.Select(t =>
    {
        var dto = ObjectMapper.Map<Tenant, SaasTenantDto>(t);

        // Critical line:
        t.MapExtraPropertiesTo(dto);

        return dto;
    }).ToList();

    return new PagedResultDto<SaasTenantDto>(totalCount, dtos);
}

With that, your JSON-only extension property (TaxNumber) will be present in the returned SaasTenantDto.ExtraProperties, and the Host → SaaS → Tenants grid will be able to render the cell values again.

Answers to your questions (based on verified ABP behavior):

  1. It matches a missing “map extra properties” step in the SaaS tenant listing/mapping path. Whether it is an intentional change or a regression in 10.3.0 can’t be conclusively verified from the available sources here.
  2. MapEfCoreProperty is not required just to display values. It’s a persistence/query optimization choice. JSON-only should work as long as entity → DTO mapping copies extra properties.
  3. Yes, a clean 10.3.0 template can reproduce this class of issue whenever an app service returns DTOs without mapping extra properties.

  • Your analysis is correct: ABP background jobs execute under the tenant determined by BackgroundJobExecuter.GetJobArgsTenantId(jobArgs), and when the args don’t implement IMultiTenant, the executer falls back to CurrentTenant.Id (which is typically null on the worker), so the job runs in host context.
  • With Azure Blob Storing, the blob name is tenant-scoped by default: it prefixes the blob path with tenants/<tenant-id> when the current tenant is not null. So running the indexing job in host context makes it look under the wrong blob key.

What to do (workaround you can apply now)

  1. Ensure the job args carries the TenantId by implementing IMultiTenant and including TenantId in the serialized args.
  2. Enqueue the job with TenantId populated from the current tenant at upload time.

Example (conceptual fix):

using System;
using Volo.Abp.MultiTenancy;

public class IndexDocumentJobArgs : IMultiTenant
{
    public Guid? TenantId { get; set; }
    public Guid DataSourceId { get; set; }
}

When enqueueing:

await _backgroundJobManager.EnqueueAsync(
    new IndexDocumentJobArgs
    {
        TenantId = _currentTenant.Id,
        DataSourceId = dataSourceId
    }
);

This makes BackgroundJobExecuter switch to that tenant before calling ExecuteAsync, so the blob provider will resolve the correct tenants/<tenantId>/... prefix.

If you can’t change the args type (alternate workaround)

Wrap the job execution with an explicit tenant change (only works if you can determine tenantId from DB by DataSourceId without requiring tenant context, e.g., host-visible table or query with disabled filter):

using (_currentTenant.Change(tenantId))
{
    // read blob + index
}

Notes / expectation

Given how ABP blob naming works, the job must run under the same tenant that uploaded the blob (or you must disable multi-tenancy for that blob container, which would change the storage layout and isolation semantics).

  • Recommended migration path (ABP 9.3.2 → 10.4.0)

    1. Upgrade ABP to v10 first (keep your current .NET SDK only if your environment supports building ABP 10; ABP 10 is on .NET 10). Follow the ABP 10.0 migration guide and apply its breaking changes.
    2. After you are green on ABP 10.0.x, move forward incrementally to 10.1 → 10.2 → 10.3 → 10.4, applying each version’s migration guide (especially important for Blazor UI / Blazorise changes in 10.2).
    3. Only after each step builds and runs, regenerate code (Suite CRUD) and fix UI-level breakages.
  • AutoMapper → Mapperly strategy (officially supported)
    ABP v10 switches the default mapper used by ABP modules to Mapperly, while AutoMapper integration still exists for backward compatibility. The safest approach is:

    • Phase A (stabilize quickly): Keep your existing AutoMapper profiles temporarily by ensuring every layer that uses ObjectMapper has AutoMapper correctly registered (especially your Blazor module).
    • Phase B (migrate cleanly): Move mappings to Mapperly using ABP’s documented pattern (AbpMapperlyModule, AddMapperlyObjectMapper, and Mapperly mapper classes derived from MapperBase<,> / TwoWayMapperBase<,>).

    Practical “gotcha” that causes “No object mapping was found…”: if you register a contextual object mapper (e.g. AddAutoMapperObjectMapper<MyBlazorModule>() or AddMapperlyObjectMapper<MyBlazorModule>()), you must also set the ObjectMapperContext where you call ObjectMapper.Map(...) (Blazor pages/components commonly hit this). This is a known real-world fix pattern in ABP support.

  • Navigation properties / WithNavigationProperties DTOs There isn’t a single “one breaking change” bullet in the public sources you provided that explains all navigation/collection-related DTO generator problems. In practice, what you’re describing is commonly a mapping registration + generated DTO shape mismatch problem after switching mapping provider and/or regenerating code. The most deterministic fix path is:

    • Decide one mapping provider per layer (prefer Mapperly in v10+), and ensure it’s registered as the default provider (context.Services.AddMapperlyObjectMapper();) in a root module that is always loaded.
    • For WithNavigationProperties DTOs, add/verify explicit mappings for:
      • EntityWithNavigationProperties ↔ EntityWithNavigationPropertiesDto
      • nested lookup DTOs used by CRUD pages (these are frequently the missing ones after regeneration)
  • ABP Suite / CRUD Page Generator compatibility ABP Suite can generate for v10, but if you migrate an existing v9 solution and then regenerate, you should expect manual adjustments where your project has custom conventions (navigation display properties, custom DTOs, Identity Pro integration patterns, etc.). Treat generator output as a starting point; stabilize compilation after each regeneration step.

  • Recommended upgrade order (minimizes churn)

    1. ABP 10.0 migration guide items first (core framework + mapping provider changes).
    2. Mapping decision:
      • either keep AutoMapper temporarily across all layers, or
      • migrate to Mapperly and ensure AddMapperlyObjectMapper() is called so ObjectMapper.Map uses Mapperly.
    3. UI upgrades next:
      • if you go through ABP 10.2, you must handle Blazorise 2.0 migration changes there (that’s where many component API breaks like parameters/events happen).
    4. Only then re-apply/regenerate CRUD pages and fix remaining compilation issues.

  • AllowedProviders (set via WithProviders(...)) is intended to restrict which value providers are considered at runtime for that feature. So in your example, if the feature only allows TenantFeatureValueProvider.ProviderName (“T”), then IFeatureChecker will ignore the edition (“E”) value even if one exists, and only tenant/default can take effect.
  • In ABP 10.1.1, the Feature Management UI/API (including the SaaS Edition Features dialog) does not automatically hide/disable features based on FeatureDefinition.AllowedProviders. As a result, it can still let you save an edition-level value that will never be used at runtime for that feature. This is essentially a UX mismatch: the stored value is valid data, but it is not applicable given the feature definition’s allowed providers.

What you should do to avoid the “configurable but ignored” situation:

  1. Preferred (keep behavior consistent): allow “E” if you want it configurable in Edition Features
context.AddGroup("MyGroup")
    .AddFeature("MyFeature",
        defaultValue: "false")
    .WithProviders(
        TenantFeatureValueProvider.ProviderName,
        EditionFeatureValueProvider.ProviderName
    );
  1. If you intentionally want tenant-only configuration, then you should treat edition configuration as irrelevant and (today) you must enforce that at the UI layer yourself:
  • Customize/extend the Feature Management UI so that when editing an Edition you filter out (or disable) any feature whose AllowedProviders does not include "E".

No verified source available for this specific UI behavior detail in ABP 10.1.1 (the runtime provider filtering is consistent with the feature system’s “Feature Value Providers executed one by one” design, but the “Edition Features dialog should hide/disable based on AllowedProviders” behavior is not documented/guaranteed).

  • This usually happens when the locally installed ABP Suite package gets into a bad state (the UI starts, but the Modules page can’t load its data correctly). The verified fix is to remove and reinstall Suite via ABP CLI:
abp suite remove
  abp suite install

Then start Suite again:

abp suite
  • If you also have issues downloading module source codes from the Modules page, re-authenticate in CLI (since Suite relies on the same ABP CLI login session):
abp logout

  • This is a LeptonX theme bug/limitation in the “custom select” overlay implementation: LeptonX hides the native <select> (where Blazorise applies is-invalid, aria-invalid, aria-describedby, and where the <ValidationError /> feedback is associated) and renders a proxy element (e.g. .custom-select-display). The proxy does not mirror the validation state, so you don’t see the red border and the validation message behavior you get with TextInput.

  • Workaround (recommended): avoid the LeptonX custom-select overlay for the affected fields so the real <select> remains the visible/styled control.

    • If you can, render a native <select> (or otherwise ensure the element does not get enhanced by LeptonX’s custom select script/CSS in your setup).
    • In practice, the simplest workaround is to not use the form-select-enhanced path for those selects (the LeptonX overlay targets Bootstrap-styled selects). For pages/components where you need Blazorise validation visuals, use a plain select style/class that LeptonX does not transform.
  • If you must keep LeptonX’s custom select UI, then the only robust fix is on the theme side: LeptonX would need to propagate validation-related classes/attributes from the hidden <select> to .custom-select-display (and ensure feedback markup is visually associated). There isn’t an ABP-side configuration switch in the provided sources that makes LeptonX do this automatically.
