Editor margin shows up outside the editor

[nvmkpk]

I created a custom editor margin. It all works fine except for one issue. It also appears in the expression editor of watch and quick watch window. Ho do I ensure my margin is visible inside full text editor only?

It sounds like you're missing some attributes on your IWpfTextViewMarginProvider.

If you add the ContentType attribute and the TextViewRole attribute, then you should be able to get your margin to only appear on editors.

[Export(typeof(IWpfTextViewMarginProvider))]
[Name(MyMargin.Name)]
[ContentType("text")]
[TextViewRole(PredefinedTextViewRoles.Document)]
public class MyMargin : IWpfTextViewMarginProvider {
    // ...
}

There are different types of roles that you can use. You can see the pre-defined roles here: https://docs.microsoft.com/dotnet/api/microsoft.visualstudio.text.editor.predefinedtextviewroles

I already have both of those attriutes. TextViewRoleAttribute had PredefinedTextViewRoles.Interactive. After posting this question, I tried a few other members of PredefinedTextViewRoles but somehow I missed PredefinedTextViewRoles.Document. This fixed the issue, thank you.
