I'm converting my .NET Framework 4.8 application to .NET 5, and have made it to the point where I'm able to build and run the application without issue, but when opening some of my User Controls in the Forms designer, I get a System.TypeLoadException with the following message:
Could not load type 'Microsoft.VisualStudio.DesignTools.Extensibility.Actions.SuggestedActionProvider' from assembly 'Microsoft.VisualStudio.DesignTools.Interaction, Version=16.9.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
Any ideas what could be causing this issue and how to get around it? I really need to be able to use the designer to maintain these forms, and was hoping the .NET 5 desktop Forms support was strong enough at this point that I'd be able to migrate without running into too many difficulties.
