WASM + Server Hosted: TypeLoadException Due To Transient DLL Dependency #117

Closed warappa closed 3 years ago

warappa commented 3 years ago

Info

LiveSharp 2.0.9 LiveSharp.Server 2.0.6

Affected Versions

LiveSharp 1.6.x (or even ealier).

Issue

When using WASM Blazor with Kestrel hosting you need to reference the WASM project from the server project.

Usually it works, because the server tries not to load everything from the WASM project - in this case LiveSharp.Support.BlazorWASM.dll.

Cause

I changed the server's JsonOptions and got a TypeLoadException from Unknown Module. After some try-and-error I found that removing AddJsonOptions fixes the issue. Here's the service configuration:

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews()
        //.AddJsonOptions(configure =>
        //{
        //    configure.JsonSerializerOptions.Converters.Add(new Client.TimeSpanConverter());
        //})
        ;

        ...
}

Root Cause

I think TimeSpanConverter causes the loading of LiveSharp.Support.BlazorWASM.dll and tries to load it. But in the server project it is not copied to the output folder.-

Proper Fix (Guess)

I guess it's how the DLL gets injected by the msbuild task. It should copy transient LiveSharp dependencies from client project to server project.

Workaround

Currently the only way to fix this is to take a direct dependency to the NuGet's DLL file in .csproj-file like this:

<ItemGroup>
    <Reference Include="LiveSharp.Support.BlazorWASM">
      <HintPath>C:\Users\spoil\.nuget\packages\livesharp\2.0.9\build\LiveSharp.Support.BlazorWASM.dll</HintPath>
    </Reference>
  </ItemGroup>

Exception

System.TypeInitializationException: 'The type initializer for '<Module>' threw an exception.'

Inner Exception
FileNotFoundException: Could not load file or assembly 'LiveSharp.Support.BlazorWASM, Version=1.6.2.0, Culture=neutral, PublicKeyToken=null'. Das System kann die angegebene Datei nicht finden.

Callstack (from Browser output)

TypeInitializationException: The type initializer for '<Module>' threw an exception.

I'm adding LiveSharp.Support.BlazorWASM.dll as None and copying it to the output directory. I think this should be enough.

@ionoy Version 2.0.13 worked instantly! Thank you!
