Error while running Blazor from a WPF application

[RobertBouillon]

Describe the bug

I am attempting to host Blazor out of a WPF application. I'm able to host an MVC site by referencing the MVC project and calling Program.Main from the WPF application. Attempting to host a Blazor site in the same way results in the following error:

Could not load type 'WebAssembly.JSInterop.JSCallInfo' from assembly 'Microsoft.JSInterop.WebAssembly, Version=5.0.5.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' because it contains an object field at offset 4 that is incorrectly aligned or overlapped by a non-object field.'

The error encountered is similar to an issue described by #26882 and resolved by #26931.

To Reproduce

https://github.com/RobertBouillon/BlazorReferenceBug

1. Create a new WPF project (or Console Project)
2. Create a new Blazor WASM project
3. Change the Blazor WASM project output type to Library
4. Add a reference to the Blazor project from the WPF project
5. Make a call to Blazor's Program.Main from WPF's OnStartup in the App.xaml.

Exceptions (if any)

System.TypeLoadException: Could not load type 'WebAssembly.JSInterop.JSCallInfo' from assembly 'Microsoft.JSInterop.WebAssembly, Version=5.0.5.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' because it contains an object field at offset 4 that is incorrectly aligned or overlapped by a non-object field.
