SharePoint & Project Server Remote debugging

In the following text, „Production“ is server environment on which solution is deployed and which you need to debug for errors.  „Test“ is server environment on which your code is located and Visual Studio is installed.
 

User on „Test“ and user on „Production“ must have same username, they do not have to be in the same domain, but, they must have same username / logon name.

1. First check on „Test“ does msvsmon.exe exist in:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger\x64\

or in:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger\x64

If you have msvsmon.exe on „Test“ skip step 2 and go to step 3.

2. If msvsmon.exe does not exist, it can be downloaded from the Microsoft's web pages.

(there is 64 bit and 32 bit version, choose the version that matches your environment) 

3. Copy to msvsmon.exe to „Production“ and Run it as Administrator

4. User on „Production“ must have permissions for debugging

5. Build and deploy your solution/wsp to the server (make sure that the versions of application on „Test“ and applications code on „Production“ are the same

6. Copy the .pdb file from your build directory from „Test“  to the GAC folder on the „Production“ 

NOTE: You can't open GAC folder and copy there directly, follow these steps to copy:

· On „Production“ go to Start à Run

· Write c:\windows\assembly\gac_msil

· Now, you can copy file to the folder where your application  is located in GAC

7. Back to „Test“ and open Visual Studio with code of application

8. Go to Debug --> Attach to process

9. Write the name of „Production“ machine in field Qualifier

10. Attach to appropriate (or all) w3wp.exe

It should sit there for a while loading a whole bunch of symbol files

You should now be able to debug the server
