exception ILLink when building Blazor WASM hosted in Release mode

[Stefan]

Hi,

I am trying to publish a blazor WASM hosted app in Release and while building is gives below exception:

nuget\packages\microsoft.aspnetcore.components.webassembly.build\3.2.1\targets\Blazor.MonoRuntime.targets(326,5): error : Unhandled exception. Mono.Linker.LoadException: Error while processing references of 'Telerik.Blazor, Version=2.24.0.0, Culture=neutral, PublicKeyToken=20b4b0547069c4f8'

Is the Telerik blazor package not compatible in some way with ILLinker?

Hi Stefan,

Can you confirm you are targetting .NET 5? The .NET Core 3.2.1 flavor of WebAssembly has been deprecated by Microsoft (see more here) and there might be issues with building against it.

I'm attaching here a small sample you can compare against that seems to work fine for me (both from the VS GUI - build in release mode, and publish, and from the CLI - build in release mode and publish).
