I'm actually trying to fix this issue where my projects are always out of date by using the steps outlined in this answer to enable system logging.
However I can't find devenv.exe.config or the matching .exe file anywhere on my machine let alone in either C:\Program Files or C:\Program Files (x86).
I'm running Windows 7 SP1 (which I presume isn't particularly relevant) and VS2010 Express SP1. I was thinking that maybe devenv isn't available in the Express version but I can't find any info to either confirm or deny my theory.
Can anyone suggest why I don't have devenv.exe and whether I should or not?
If not, how do I fix the "always out of date" issue without being able to get a proper log that tells me what's causing the problem?
The name of the executable (and, of course, the associated configuration file) is dependent upon which type of Visual Studio you're running. Normally, this is devenv.exe. In the case of Visual Studio Express, you should be able to locate vcexpress.exe.
A similar configuration file is available as vcexpress.exe.config, and you should be able to place your system.diagnostics configuration in that file.
you can find your path by
- right click on icon and select property window
- in shortcut tab you can find out in target textbox
In my VS 2012 Express it looking as :
"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VWDExpress.exe"
In my case of "Microsoft Visual Studio 2012 Express Version4 for Windows Phone" it's the path "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\VPDExpress.exe"
Just start a new process from task manager as shows below
File>Run New task>devenv.exe
In the case of "Microsoft Visual Studio 2010 Express for Windows Phone" it´s the VPDExpress.exe (.config) \Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE
