'<method1>' and '<method2>' cannot overload each other because they differ only by return types
You have attempted to overload a method with another method that differs from the first only in its return type. In overloading, you must differentiate any two versions of a method by their argument lists; you cannot use anything other than argument lists to differentiate the methods.
Error ID: BC30301
To correct this error
Ensure that the methods are differentiated by their argument lists.
