How to create an SSIS custom task that references another library

Question

How can one successfully reference a library from an SSIS Task library? EX: MyCompany.SsisTasks.AwesomeTask have a reference to MyCompany.SsisTasks.Common? When I try to do this, this is what pops up:

Could not load file or assembly 'AwesomeTask, PublicKeyToken=xxxxxxxxxxxxxxxx' or one of its dependencies. The system cannot find the file specified.

I have created a new SSIS task doing all of the basic steps (inhert from Microsoft.SqlServer.Dts.Runtime.Task, etc). Doing this worked like a charm, and everything was fine. The project has expanded and I now am referencing another library with this task. When I add the task to SSIS now, I get the aforementioned error. So it would seem I am incorrectly referencing "one of its dependencies." I am curious if anyone has experience with this.

Solution is this: make sure all assemblies are in the GAC, and also make sure that when referencing other assemblies (UITypeString, for instance) to include Class, Assembly, Version, Culture, and PublicKeyToken.
