Cannot determine implicit type arguments in call of generic method method
One or more argument types in a generic method were not explicitly declared, and the compiler could not infer the types from the arguments in the called method.
For example, for the following generic method declared with type arguments T and R:
method meth1<T,R>, void parm1, T parm2, R proc end
you would probably provide the types for T and R when calling the method, e.g.,
However, the compiler also can infer types from the type of arguments in the call. If val1 was an int and val2 was a long, the compiler would infer the call
If the compiler can't infer these types, an IMPTYARG error occurs. To fix the problem, you can declare the types explicitly.
