.net interfaces project type

[Saumitra Kumar Paul]

Dear friends,

I am planning to use interfaces in my .net project.

I would like to add a new project "MyInterfac es" in my existing solution. "MyInterfac es" intends to contain all the necessary interfaces of the solution.
But i am somewhat confused about the project type. What type of project should i choose to start "MyInterfac es"? Class Library, or something else?

Then, what type of item would i add into that project to declare an interface? Interface or class?

Please let me have a good start and obliged my by providing a tiny help.

Regards
SKPaul

I normally just add them in as a file within the project.

If you wish to use the interfaces in a number of projects, or perhaps distribute them as some form of interaction with your software, I suggest creating a DLL(Class Library) for them
