See [https://github.com/leonvandermeer/WorkerSdkWpfIssue](https://github.com/leonvandermeer/WorkerSdkWpfIssue) for a repository that reproduces the issue **and for a more in depth analysis.**

### Reproduce

>dotnet.exe new worker -o WpfWorkerApp

2. Add following line to the WpfWorkerApp.csproj file to enable Wpf:
>true

3. In Visual Studio, add a new `Window (WPF)` item to the project, so that Wpf's xaml compile steps get executed.
