Because this tool produces C# source code rather than a compiled dll the user is free to make any changes necessary to the code before use. So the ambiguity problem is solved by the application picking one particular .NET type to use in the P/Invoke method signature and if necessary the user can change this to the required type.
A method has a return value, a name and usually some parameters initialized when it is called with some arguments. It can either belong to an instance of a class or be a static member. class Foo { int Bar ( int a , int b ) { return a % b ; } }
A new pseudo-type dynamic is introduced into the C# type system. It is treated as System.Object, but in addition, any member access (method call, field, property, or indexer access, or a delegate invocation) or application of an operator on a value of such type is permitted without any type checking, and its resolution is postponed until run-time.
The implementation in the subclass overrides (replaces) the implementation in the superclass by providing a method that has same name, same parameters or signature, and same return type as the method in the parent class. [2] The version of a method that is executed will be determined by the object that is used to invoke it.
The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5.It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime.

In the following C# code, method Helper.Method uses parameter callback as a blocking callback. Helper.Method is called with Log which acts as a callback function. When run, the following is written to the console: "Callback was: Hello world".
Return types and thrown exceptions are not considered to be a part of the method signature, nor are the names of parameters; they are ignored by the compiler for checking method uniqueness. The method signatures help distinguish overloaded methods (methods with the same name) in a class. Return types are not included in overloading.
Property methods may take parameters; Properties can be passed to methods with ByRef parameters (ref parameters in C#). In C# you have to write three additional instructions: Declare a variable, copy the property value into the variable and copy the variable back to the property after the method call. Enums can be defined inside interfaces
