Compiler Error CS0727
This error occurs in the debugger. When you type a variable name into one of the debugger windows, you can follow it with a comma, and then a format specifier. Examples are: myInt, h; or myString,nq. This error arises when the compiler is completely unable to parse what you typed in. To resolve this error, retype the variable name, optionally followed by a comma and a valid Format Specifier.
