For your question i just want to highlight the points specified in MSDN. As per the MSDN documentation :: is used for: in larger projects it is a very real possibility that namespace duplication may occur in one form or another. In these situations the global namespace qualifier is your guarantee that you can specify the root namespace. For more information i suggest go thru the below link which had a simple and clean example to understand it. https://msdn.microsoft.com/en-us/library/htccxtad.aspx Hope this helps!

Hi The namespace alias qualifier ( :: ) is used to look up identifiers. It is always positioned between two identifiers as in this example: global :: System . Console . WriteLine ( Hello World );
