To resolve the error "Could not find file '/libs/prismjs/themes/prism-okaidia.css'" when running the VoloDocs application, you need to install the required client-side libraries. ABP Framework uses a client-side resource management system, and these libraries are not included in the ZIP by default.
Solution:
abp install-libs
This command will copy all necessary client-side libraries (like PrismJS) into the /wwwroot/libs folder.
This will resolve the missing /libs/prismjs/themes/prism-okaidia.css error and allow the application to run correctly.

你遇到的“页面一小时后自动刷新回到主页面”问题，是由于 ABP 的“Idle Session Timeout（空闲会话超时）”功能导致的。默认情况下，空闲1小时后会自动登出并回到主页面。
你可以在系统后台的“设置 > 账户 > 空闲会话超时（Idle Session Timeout）”页面，关闭或调整这个功能。将其禁用或设置更长的超时时间即可。
注意：如果登录时勾选了“记住我（Remember Me）”，则该功能会自动失效，不会自动登出。

The issue you are experiencing with the Swimlane datatable component in ABP Angular (v9.2.4)—where the grid does not fit the card container, column widths are not recalculated after data load, and the page ignores resize events—is a known challenge with dynamic data tables and container-based layouts.
To address this, you should ensure that:
recalculate() method on the table component after data is set.recalculate() method to ensure the table adapts to container or window size changes.Example for handling resize and recalculation in Angular:
import { ViewChild, AfterViewInit, HostListener } from '@angular/core';
import { DatatableComponent } from '@swimlane/ngx-datatable';
export class YourComponent implements AfterViewInit {
@ViewChild(DatatableComponent) table: DatatableComponent;
ngAfterViewInit() {
// Call after data is loaded
setTimeout(() => this.table.recalculate(), 0);
}
@HostListener('window:resize', ['$event'])
onResize(event) {
this.table.recalculate();
}
}
Make sure your CSS does not set the table or its container to width: auto without constraints, as this can cause overflow.
If you are using ABP's card or container components, ensure they have overflow: auto or overflow-x: auto set, so scrollbars appear when needed.
If the problem persists, check for any custom styles or layout wrappers that might interfere with the datatable's sizing logic.

To resolve the ABP-LIC-0012 license error ("maximum allowed developer computer count reached"), you need to reset the developer computer activations for your organization. This typically happens when the number of unique machines used by a developer exceeds the allowed limit.
Steps to fix:
This will allow you to clear the previous activations and register new computers as needed.

To support both default (definition-based) and dynamic templates in ABP's TextTemplateManagement, you need to understand how each template type is managed and persisted:
TemplateDefinitionProvider and are not persisted in the database by default. They exist in memory and are typically loaded from embedded resources or the virtual file system.TemplateContentAppService: In your custom service, when handling updates or restores, check if the template exists in the database. If not, create a new record to override the default. For dynamic templates, update the existing record.public override async Task UpdateAsync(UpdateTemplateContentDto input)
{
var template = await _templateContentRepository.FindAsync(input.Name, input.CultureName);
if (template == null)
{
// Create override for default template
template = new TextTemplateContent(
GuidGenerator.Create(),
input.Name,
input.CultureName,
input.Content
);
await _templateContentRepository.InsertAsync(template);
}
else
{
// Update dynamic or overridden template
template.SetContent(input.Content);
await _templateContentRepository.UpdateAsync(template);
}
}
public override async Task RestoreToDefaultAsync(RestoreTemplateContentDto input)
{
var template = await _templateContentRepository.FindAsync(input.Name, input.CultureName);
if (template != null)
{
await _templateContentRepository.DeleteAsync(template);
}
// Now, the system will use the default definition if it exists
}

In ABP Framework microservice projects, each service often uses a "no layer" (single-layer) structure instead of a traditional N-layer (multi-layer) structure for several reasons:
Microservice Simplicity: Each microservice is designed to be small, focused, and independently deployable. Adding multiple layers (like Application, Domain, Infrastructure, etc.) can introduce unnecessary complexity for services that handle a limited scope.
Reduced Overhead: Many microservices are simple CRUD or integration endpoints. The overhead of maintaining strict layering is not justified for such straightforward logic.
Faster Development: A single-layer structure allows for faster iteration and easier maintenance, especially when the service is not expected to grow significantly in complexity.
Deployment Independence: Microservices are independently deployed and versioned. The boundaries enforced by N-layer architecture in monoliths are less critical when each service is already isolated by process and API.
ABP Support: ABP provides both layered and single-layer templates. For microservices, the single-layer template is recommended to avoid boilerplate and keep the service lightweight.
Best Practice in Microservices: Industry best practices suggest keeping microservices as simple as possible. Layered architectures are more beneficial in large, monolithic applications where separation of concerns is critical.
If a microservice grows in complexity, you can still refactor it into a layered structure as needed.

In ABP Blazor WASM applications, external authentication callback endpoints (like /signin-microsoft-workforce) must be handled by the backend (API host or AuthServer). A 404 error on Azure for /signin-microsoft-workforce usually means the backend is not configured to recognize or route this path.
Common causes and solutions:
/signin-microsoft-workforce. The endpoint must be registered in the backend's authentication middleware./signin-microsoft-workforce is registered in the correct Azure App Registration (for the correct tenant/client)./signin-microsoft-workforce are forwarded to the backend and not intercepted by the frontend (Blazor WASM) static file handler./signin-microsoft-workforce to index.html (the Blazor app), but instead allow it to reach the backend.CallbackPath in your backend authentication configuration must exactly match the path registered in Azure and the one being called by the authentication flow.How to check/fix:
.AddMicrosoftAccount("WorkforceEntra", options => {
// ...
options.CallbackPath = "/signin-microsoft-workforce";
// ...
})
web.config to exclude /signin-microsoft-workforce from being routed to the Blazor app. Example:<rule name="Exclude Auth Callbacks" stopProcessing="true">
<match url="^signin-microsoft-workforce$" />
<action type="None" />
</rule>
Make sure the backend is accessible at the deployed URL and not just locally.
Summary: The 404 is almost always due to routing or middleware configuration on the backend or web server, not the ABP or Microsoft Account provider itself. Ensure the backend is set up to handle the callback and that your server/proxy does not intercept or misroute the request.

To use a custom implementation of AbpStringLocalizerFactory in ABP, you must ensure that your replacement is registered in the correct module and project, and that it is picked up before any localization services are resolved. Here are the steps and checks to ensure your custom factory is used:
Correct Service Replacement
[Dependency(ReplaceServices = true)] and [ExposeServices(typeof(IStringLocalizerFactory), typeof(IAbpStringLocalizerFactory))] as you did..Domain.Shared or .Web module, depending on your architecture).Module Registration
.HttpApi or .Web project, not just in .Application or .Domain).Service Lifetime
Transient lifetime for IStringLocalizerFactory. Ensure your custom implementation is also registered as transient.Virtual File System and Embedded Resources
EmbeddedResource in your .csproj file. Otherwise, ABP may not find your custom resources, especially in production.Check for Multiple Registrations
IStringLocalizerFactory, it may override yours. Use ABP's context.Services.Replace in your module's ConfigureServices method to ensure your implementation is the last one registered:context.Services.Replace(
ServiceDescriptor.Transient<IStringLocalizerFactory, PerformanceTrackingStringLocalizerFactory>()
);
context.Services.Replace(
ServiceDescriptor.Transient<IAbpStringLocalizerFactory, PerformanceTrackingStringLocalizerFactory>()
);
Debugging Registration
Reference Official Docs
Production vs Development
Summary of what to check:
context.Services.Replace in ConfigureServices.EmbeddedResource if you override them.If you follow these steps and your custom factory is still not called, review the module dependency order and ensure your module is loaded last or after all ABP modules that might register their own factory.
