ComWrappers required to run NativeAOT and WinForms

This repository has ComWrappers implementation for WinForms. In additional to that, it allow use WinForms and NativeAOT and R2R with trimming together.

Getting started

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);

Also

1. Add <PackageReference Include="Microsoft.Web.WebView2" Version="1.0.1462.37" /> as depedency. This library would work only starting from this version of WebView2 package.
2. Add RD.xml file from https://github.com/kant2002/RdXmlLibrary/blob/main/Microsoft.AspNetCore.Components.Web.rd.xml to project
3. Add <RdXmlFile Include="Microsoft.AspNetCore.Components.Web.rd.xml" /> to project file
4. Make sure that RootComponets are added to you app-specific rd.xml

<?xml version="1.0" encoding="utf-8" ?> <Directives> <Application> <Assembly Name="YourAppAssembly" Dynamic="Required All"> <Type Name="YourAppAssembly.YourRootComponent" Dynamic="Required All" /> </Assembly> </Application> </Directives>
