Answer 1

You don’t get much information from that stack trace. You can read the Image name, which is the name of the assembly where the methods are, and the Function name, which is the name of the method.

It looks like there was an exception in the GeoCaching.Main.btnGoToPin_Click or TransitionStub methods, but the stack trace alone doesn’t tell you what kind of exception, or what information was put in the Exception object.

If you would have compiled the application with debug information on, you would get some more information in the stack trace, like the line number in each method.
