Q:

Referenced assembly targets a different processor than the application

Using VS 2010 Express.
This question has been asked before, in this post: How to solve warning "Referenced assembly targets a different processor than the application"
But when I go to my project properties I don't have a compile tab. The Build tab lists a platform combo box, but I only have one option to choose from which is 'Active(Any CPU'.  
Maybe this is due to me using the express version.  How else can I resolve this issue?

A:

You need to add a new configuration.
To do this, use the solution-level combo box on the main toolbar, and select Configuration Manager.
Under the 'Active Solution Platform' combo box, choose < New >.
