Exception Thrown on Blazor WASM

[LuvForAirplanes]

I am trying to use this package on my Blazor WASM (client-side) project. The goal is to reflect my database service set out to the client so service methods can be called without calling web APIs.

I'm running into this exception:

blazor.webassembly.js:1 crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Cannot emit a CustomAttribute with argument of type System.RuntimeType.

And here is my code: (from the front page of the repo)

   //Dynamic Expando object
    dynamic expando = new ExpandoObject();
    expando.Prop1 ="Test";
    expando.Prop2 = 42L;
    expando.Prop3 = Guid.NewGuid();
    expando.Meth1 = Return<bool>.Arguments<int>(it => it > 5);
    IMyInterface myInterface = Impromptu.ActLike(expando);

For others wanting to use this on Blazor client-side, comment out this line and you should be set to go:
https://github.com/ekonbenefits/impromptu-interface/blob/master/ImpromptuInterface/src/EmitProxy/BuildProxy.cs#L332
Actually lines 332-334.

interesting, I don't know why it would be trying to generate a the metadata attribute with a RuntimeType as the argument. From the code you provided above it should be trying to emit [ActLikeProxy(new [] {typeof(IMyInterface)}, typeof(object)]. But your error says RuntimeType which sounds like what would happen in your other issue #44 calling typeof(X).GetType() dynamically.
