I am trying to add an assembly to the cache on Visual Studio 2010 Command Prompt. I get this error "Failure adding assembly to the cache: Attempt to install an assembly without a strong name". I am adding a ListTasks2.dll assembly from a WCF Service App called ListTasks2. I never had this issue with a similarly-named project, so why is it raising an issue now?

NOTE: I tried signing it in Visual Studio and it still doesn't work. I wonder if it might be a permission issue. I used different user credentials and was able to add an assembly. The catch is that I loaded a VS Solution, and that project signed the assembly. Should I just create a key pair?

Only strong-named assemblies can be installed into the GAC. For information about how to create a strong-named assembly, see How to: Sign an Assembly with a Strong Name.
