Strange display when developing a Visual Studio 2013 Extension "*.vsix"

I am working on a VS2013 extension. When pressing Ctrl + F5 to run the extension from the Visual Studio development environment, I see the following strange display:

enter image description here

It seems the syntax highlighting is still working, but only each line is colored excessively in purple.

But if I install my VS extension and run it by starting VS normally. The display is OK.

Anyone knows how to fix it? Is this some VS bug?

Solution

  • Issue solved.

    I added a Editor Classifier which contains the following default implementation:

    public UDKBuildDescriptionFileEditorFormat()
{
    this.DisplayName = "UDKBuildDescriptionFileEditor"; //human readable version of the name
    this.BackgroundColor = Colors.BlueViolet; // <-- HERE
    this.TextDecorations = System.Windows.TextDecorations.Underline; // <-- HERE
}

    I once added this editor classifier to my VSIX package and run it with Ctrl + F5. But it seems after I removed it from VSIX. Visual Studio doesn't know to auto remove it when running with Ctrl + F5.

    The solution is, to manually uninstall this editor classifier from Tools -> Extensions and Updates.
