COBCH1783 '%1$s' には推測可能な汎用パラメーターのある可視インスタンスメソッド '%2$s' がない

No such method was found for which the generic parameter types could be inferred. It may be necessary to specify the generic parameters explicitly. The context implies that the required method is an instance method.

           declare o = new Main
