Today I am faced with a curious challenge...
This challenge involves two .NET libraries that I need to reference from my application. Both of which I have no control over and have the same namespace within them.
So...
I have foo.dll that contains a Widget class that is located on the Blue.Red.Orange namespace.
I have bar.dll that also contains a Widget class that is also located on the Blue.Red.Orange namespace.
Finally I have my application that needs to reference both foo.dll and bar.dll. This is needed as within my application I need to use the Widget class from foo and also the Widget class from bar
So, the question is how can I manage these references so that I can be certain I am using the correct Widget class?
As mentioned, I have no control over the foo or bar libraries, they are what they are and cannot be changed. I do however have full control over my application.

In an operating system, an example of namespace is a directory. Each name in a directory uniquely identifies one file or subdirectory. As a rule, names in a namespace cannot have more than one meaning; that is, different meanings cannot share the same name in the same namespace.
Two classes with the same name can be created inside 2 different namespaces in a single program. Inside a namespace, no two classes can have the same name. In C#, the full name of the class starts from its namespace name followed by dot(.)
You can have a class in 1 to many files (if you use the "partial" keyword). You can have many classes in a namespace.
System namespace. The System namespace is the root namespace for fundamental types in . NET. This namespace includes classes that represent the base data types used by all applications, for example, Object (the root of the inheritance hierarchy), Byte, Char, Array, Int32, and String.
You need to use an extern alias - introduced in C# 2.
Anson Horton has a walkthrough on his blog which you may find useful.

I think you have to use extern alias
