Verify .NET 5 compatability

[TheWover]

With .NET 5, .NET Core and Framework are merging into one platform that will be standard across OSes. Before releasing v0.9.3, we should validate that Donut works with .NET 5 and document any relevant findings.

Any news on this? .NET 6 released already and the updated MS official hosting sample is terrible clunky and bloated: https://github.com/dotnet/samples/blob/main/core/hosting/src/NativeHost/nativehost.cpp

This is how I generate NativeAOT payloads for Athena (as requested by Wover)

dotnet publish Athena -r win-x64 --self-contained true /p:PublishSingleFile=false /p:PublishAOT=true /p:EnableCompressionInSingleFile=true /p:PublishTrimmed=true /p:DebugType=None /p:DebugSymbols=false
