Visual Studio loading symbols

Question

I'm working on a ColdFusion project for a while now, and Visual Studio started to behave strange for me at least.

I observed that when I started debugging, it built the project, it started the deploy, and the deploy finished and it was starting to load symbols for my project.

But it was very slow, and I don't know why it started to do this step. What may I have done?

Is this symbol loading step necessary? How can I disable it?

In the Tools -> Options -> Debugging -> Symbols dialog there is no Symbol file (.pdb) location added. And I pointed in my project's debug directory at the field below, and I checked the "Search the above directory only when symbols are ...." checkbox. How should I set up this dialog to turn off symbol loading?

I looked in the Modules window which symbols are loaded, but it says nothing to me. What is the problem?

Answer 1

Try right clicking at one of the breakpoints, and then choose 'Location'. Then check the check box 'Allow the source code to different from the original version'

Answer 2

Another reason for slow loading is if you have disabled "Enable Just My Code" in Debugging options. To enable this go to:

Tools -> Options -> Debugging -> General -> Enable Just My Code (Managed Only) 

Make sure this is checked.
