When I overloaded my constructors and added a property to all of my ABusinessObjects, I created the snippets below to help with the typing. Hope they help someone else.

Just add the following with the VS Code Snippet Manager and then you can type:

muProp tab tab to create a property called UserName;
muCTOR tab tab to overload the contructor to accept the property.
