Running my trimmed WPF .NET 5.0 application results in exception code 0xe0434352

Problem

I saw a lot of other issues where people seem to have issues with running a WPF app with PublishTrimmed=true.

For most of the issues the fix was to add the following item group to the .csproj file:

  <ItemGroup>
    <TrimmerRootAssembly Include="System.Collections" />
    <TrimmerRootAssembly Include="System.Runtime" />
    <TrimmerRootAssembly Include="System.Runtime.Extensions" />
    <TrimmerRootAssembly Include="System.Runtime.InteropServices" />
    <TrimmerRootAssembly Include="System.Runtime.CompilerServices.VisualC" />
  </ItemGroup>

For my project however this doesn’t seem to work. When I start my .exe file nothing happens, the only thing I see is an exception in the windows event log:

Trimming is not supported by WPF. There is now an error during compilation in .NET 6.0 when Trimming is enabled for WPF.

It was an intentional breaking change in the WindowsDesktop Sdk (WPF and WinForms). Starting with .Net 5 the Sdk will override the OutputType for WinExe. Which means that even if you set OutputType to Exe, it’ll end up being WinExe. You can override OutputType using the DisableWinExeOutputInference property:

<PropertyGroup>
  <OutputType>Exe</OutputType>
  <DisableWinExeOutputInference>true</DisableWinExeOutputInference>
</PropertyGroup>
