Note: I am using older C# coding styles...

-not using top-level statements
-not using file-scoped namespaces
-not using implicit usings
-not using 'var' keyword for declarations
-using older style 'new' statements with Type name
-using older style 'using' statements with braces

...but the issue remained even when I backed all of them. Only when I removed the line-break from the literal did the issue disappear.

BTW, awesome extension -- it really helps a lot! :-)
