add extension_list example (#281)
- Created an example of extension policy - Added C# binding support of .NET framework 4.0 and created a Nuget spec for it. - Added a pytest in python bindings to test the extension policy and the python binding - Restructured the example and Csharp binding directories due to above changes. - Added copyrights. - Added a Windows workflow for .NET 4.0 build and test.
