- **ABP Framework version: 4.0.0-rc.3
- UI type: MVC
- Tiered (MVC) or Identity Server Seperated (Angular): no
- Exception message and stack trace:
I am having all sorts of trouble with this error. Sometimes it works once, sometimes not at all
This is coming from an ABP Suite generated ApplicationService
public class CountryAppService : ApplicationService, ICountryAppService
This is being utilized by a Blazor component hosted in a razor file
<app>
<component type="typeof(CountryManager)" render-mode="ServerPrerendered" />
</app>
I had no problems whatsoever with v3.
Let me know if you require additional information. Thank you

hi, let me reproduce this issue.
is your primary key "string"?

I'm not using your default ui generation. I'm using a razor page (Index.cshtml) with a razor component inside that
<app> <component type="typeof(CountryManager)" render-mode="ServerPrerendered" /> </app>it was running fine if I inherited from CrudAppService but now I'm getting disposal is that way as well. this may have happened because I just upgraded to RC4 (which I hoped might fix the issue)
Would you like a project to test?

I don't know if this is an issue with your framework or with blazor components themselves. In the end I seem to have stable results with the following:
Iinheriting from OwningComponentBase. Note not the generic OwningComponentBase due to the Service being disposed.
using the following code, refreshing the services if they got disposed of.
protected IObjectMapper ObjectMapper => _objectMapper ??= ScopedServices.GetRequiredService<IObjectMapper>(); protected TService Service => _service ??= ScopedServices.GetRequiredService<TService>();
