Exceptions

Exception	Condition

Remarks

This constructor is useful if you do not have access to the editor factory because it is implemented elsewhere.

Examples

using MSVSIP = Microsoft.VisualStudio.Shell;
[MSVSIP.RegisterEditorExtension(typeof(EditorFactory), ".myext", 32, "{A2FE74E1-B743-11d0-AE1A-00A0C90FFFC3}", "..\\..\\Templates", 106)]
public class BasicEditor : MSVSIP.Package {}
