Hi,
I had create a custom project system with the help of https://msdn.microsoft.com/en-us/library/vstudio/cc512961.aspx. And which is working fine that I can create a project with extension of .myproj in the VS Experimental Instance window. But when I go for the properties in the created project, (Solution Explorer: Right click on the project folder and select properties) it will show an exception that "Class not registered. Looking for object with CLSID:{00000-00-00-000000}" How can I provide Properties window for this project system or can I modify the Properties window for any other default VS project system? Please help me.
