This repository has ComWrappers implementation for WinForms. In additional to that, it allow use WinForms and NativeAOT and R2R with trimming together.
Just add WinFormsComInterop
to your project.
dotnet add package WinFormsComInterop
Then to your Program.cs add following line
ComWrappers.RegisterForMarshalling(WinFormsComInterop.WinFormsComWrappers.Instance);
And modify project file to enable NativeAOT
<PublishAot>true</PublishAot>
<_SuppressWinFormsTrimError>true</_SuppressWinFormsTrimError>
If you application will works with this ComWrappers implementation, then most likely it would work with NativeAOT.
If you are using WebView2 using Microsoft.Web.WebView2.Core
package, then use
ComWrappers.RegisterForMarshalling(WinFormsComInterop.WebView2.WebView2ComWrapper.Instance);
Note, that it does not working for new WebView2 as of .NET 8, please file and issue if you need it, I'll prioritize.
Also
<PackageReference Include="Microsoft.Web.WebView2" Version="1.0.1462.37" />
as depedency. This library would work only starting from this version of WebView2 package.<RdXmlFile Include="Microsoft.AspNetCore.Components.Web.rd.xml" />
to project file<?xml version="1.0" encoding="utf-8" ?>

Test that normal CoreCLR works
dotnet run --project samples\SampleWindowsForms\SampleWindowsForms.csproj
dotnet run --project experiments\WpfTestBed\WpfTestBed.csproj
dotnet run --project experiments\WinUITestBed\WinUITestBed\WinUITestBed.csproj
dotnet run --project experiments\WinUIUWP\WinUIUWP.csproj
Test that NativeAOT works. Run commands in x64 developer tools.
dotnet publish -r win-x64 samples\SampleWindowsForms\SampleWindowsForms.csproj
"samples\SampleWindowsForms\bin\x64\Debug\net6.0-windows\win-x64\publish\SampleWindowsForms.exe"
Below are experimental projects. They are need additional work.
dotnet publish -r win-x64 experiments\WpfTestBed\WpfTestBed.csproj -p:GenerateWPF=true
blocked by https://github.com/kant2002/WinFormsComInterop/issues/30
dotnet publish -r win10-x64 experiments\WinUITestBed\WinUITestBed\WinUITestBed.csproj
dotnet publish -r win-x64 experiments\WinUIUWP\WinUIUWP.csproj
does not working due to this error
experiments\WinUIUWP\WinUIUWP.csproj : error MSB4057: The target "Restore" does not exist in the project.
Mostly notes for me, but maybe somebody would like to hack.
Build NativeAOT.
Modify nuget.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<!--To inherit the global NuGet package sources remove the <clear/> line below -->
<clear />
<!--Locally built version of NativeAOT -->
<add key="ILC" value="c:\runtimelab\artifacts\packages\Debug\Shipping\" />
<!--To use daily builds of runtime -->
<add key="dotnet6" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json" />
</packageSources>
</configuration>
Restore packages to local folder to not pollute global Nuget cache. You will build NativAOT a lot.
dotnet restore -r win-x64 --packages packages
Then publish applications using regular workflow described above.
