"There is no code editor for MainWindow.xaml" error in Blend 2019

Question

I am only getting the following error in Blend for Visual Studio 2019, when clicking on "View Code" after right-clicking in the designer view:

There is no editor available for MainWindow.xaml. Make sure the application for the file type (.xaml) is installed.

• I can open each file individually (i.e. the designer and the code-behind)
• This error does not occur in Visual Studio 2019, but in Blend
• This happens for multiple project files
• I've repaired VS with no luck

Answer 1

I fixed the issue by uninstalling Xamarin
