If you want to evaluate a number of variables or expressions in the context of the current frame, and view all of them simultaneously, you can create watches for them. The values of the watched variables and expressions are updated with each step through the application, but are only visible when the application is suspended. Unlike the evaluated expressions, the watches are saved as a part of the solution.
