Unhandled Mono AssemblyResolutionException

[tycomo]

Hi there,

I am attempting to build my application and getting the following error with the complete app not being outputted into the dist folder:

Unhandled Exception: Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'System.Windows.Forms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
   at Mono.Cecil.BaseAssemblyResolver.Resolve(AssemblyNameReference name, ReaderParameters parameters)
   at Driver.Import(String ra, AssemblyKind kind)
   at Driver.Run(String[] args)
   at Driver.Main(String[] args)
	WasmForm	C:\Users\myuser\.nuget\packages\winforms.wasm\1.0.19137.60\build\netstandard2.0\Winforms.Wasm.targets	13	

This is using version 1.0.19137.60 and .NET Core 2.1. If there is any additional information I can provide please let me know.

Does the samples work for you?
I retested it and it seems to be working fine...

Workaround in csproj:

    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>

Hi

While adding the true got me passed the 'cant resolve assembly: 'System.Windows.Forms' I simply came to another unhandled exception:
13,5): error : Unhandled Exception: Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'System.Formats.Asn1, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

Any idea how to get past this problem?
