Hi, I have a question about the number of rest requests that blazor webassembly makes to the server at the same time.
I have some interfaces that make several requests, and I observe that at the same time 5 requests are made, while others are waiting. Is this limited for some performance reason? Is it parameterizable from some XXXModule?
In case it helps, I use static clients in the api, generated with the abp cli command.
Hi, I am experiencing performance problems when working with requests up to 120 seconds maximum.
The main problem is the blocking of the tables on which I am inserting/updating in the same operation. I am transferring the development team's proposal for improvement: In this process an endpoint of an App Service is called which, in turn, invokes an external service to read information. The theory is that before the UoW (Unit of Work), when synchronising an entity, was managed with the default configuration: on receiving the request, the API opened the UoW and, on completion, it was completed and the changes were automatically saved. What happens? Fetching data from the external API can take tens of seconds for the UoW to complete, which keeps the transaction open and causes crashes in the database (which are most of the errors we are seeing now).
We doubt that this is actually causing these database timeouts, since the database transaction is understood to start and end when SaveChangesAsync is called. We don't know to what extent it makes sense that, when starting a transactional Unit of Work, these table locks occur.

I need to remove this section of the application, i can't find how in the documentation:
Previously I had an application in blazor webassembly since it was born in net core 6. After migrating to Blazor WebApp I am having problems since one of my components injects the IAccessTokenProvider interface (belongs to Microsoft.AspNetCore.Components.WebAssembly.Authentication.dll).
After the migration this service is no longer injected, moreover, I have tried to inject IAbpAccessTokenProvider, but the implementation I get is Volo.Abp.AspNetCore.Components.WebAssembly.WebApp.CookieBasedWebAssemblyAbpAccessTokenProvider, which after reviewing its code, returns a null string.
By default I use InteractiveAutoRenderMode with prerender set to false. I've tried to indicate in the component that it uses the InteractiveWebAssemblyRenderMode interface but it doesn't solve anything. Any idea?
Hi, I am having some problems migrating a solution from blazor web assembly to blazor web app.
I have tried the steps mentioned in the different links: https://abp.io/docs/latest/release-info/migration-guides/abp-8-2-blazor-web-app https://abp.io/support/questions/8378/Render-Modes https://github.com/abpframework/abp/issues/20128
The documentation is not clear, it does not detail anything step by step, it does not indicate if you have to create a new solution, create new projects... In the documentation it is mentioned that you have to run the project "Blazor.Webapp" and the cli only generates "Blazor" and "Blazor.Client". I need a solution because I have to migrate 6 solutions.
Attached are screenshots of the errors I have found:
There are many errors that I am finding
Good morning, In a new project created with the CLI I tried to overwrite the Login.cshtml file. I have searched for documentation, tried solutions discussed in other threads.... But the changes are never applied, could you give me a project with a custom Login.cshtml?
