First task to create a nuget package and remove sources from mono/mono

[thaystg]

Removing usage of AsyncCallback and AsyncResult, this is not available in netstandard.

Changing projects to use new csproj style.

Just a heads up - there's some kind of Mono.Debugger.Soft package already published (by us?) in 2017: https://www.nuget.org/packages/Mono.Debugger.Soft/

[jpobst]

Any plans to complete this? (At least the part about moving to SDK-style projects.)

We need this for Xamarin.Android in order to build with dotnet, which we need in order to move to .NET5/6.

This comment does not make sense to me, as public documentation states that these types exist ~everywhere:

• https://docs.microsoft.com/en-us/dotnet/api/system.iasyncresult?view=net-5.0
• https://docs.microsoft.com/en-us/dotnet/api/system.asynccallback?view=net-5.0

Note in particular:

.NET Standard: 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 2.0, 2.1

Why do these types need to be removed?

The netstandard.dll for net4.5 also contains the forwarders:

% monodis --forward-decls /Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/4.5/Facades/netstandard.dll | grep IAsyncRes
.class extern forwarder System.IAsyncResult

% monodis --forward-decls /Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/4.5/Facades/netstandard.dll | grep AsyncCallb
.class extern forwarder System.AsyncCallback

TaskFactory<T>.FromAsync() can be used to "bundle together" a Begin+End method pair into something that returns a Task.

There is a blog post detailing something about this: https://devblogs.microsoft.com/dotnet/migrating-delegate-begininvoke-calls-for-net-core/
