Never seen such error before. If you have Radzen license you can send us an application where we can reproduce it at info@radzen.com.

I am testing community edition with one app so no license. I downgraded and works fine now

I too upgraded to the latest version of the Radzen client this morning and I am also getting an error to do with the Security Service and Lifetime: Scoped ImplementationType.

Easy repro is to make a brand new Blazor app with a default / sample db. Add the security to it and it will not work:

System.AggregateException: Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Tingz.SecurityService Lifetime: Scoped ImplementationType: Tingz.SecurityService': Unable to resolve service for type 'Tingz.GlobalsService' while attempting to activate 'Tingz.SecurityService'.)

It appears that if I add

services.AddScoped();

To the ConfigureServices method prior to any of the other AddScoped calls I can get the application to run.

I could not find any existence of adding the GlobalsService to the source code prior to me adding this

I've managed to reproduce the problem. Fix will be published immediately.

I recently updated to .NET 8 LTS and am now getting the

"dotnet: watch : Exited with error code -532462766"

error when I try to open apps created prior to the .NET 8 LTS install, as well as with newly created apps using the .NET 8 Web Assembly option.

@Frank_Lineberger I don’t know what can cause such error and I think that this is not related to the problem in this thread.

@enchev oneapp.igcc.winservice.exe started using the same port for some reason. I went into the launchsettings.json file and changed to a new port and it fixed the issue. Thanks!
