Mistake 1: Running vsexe.exe Without Cleaning After a Crash

Symptom: VSP1001 or VSP1023 errors.
Fix: Run vsprefixcleanup.exe, then VSPerfClrEnv /off, then retry.

Chapter 6: Real-World Workflow – Using Both Tools Together

Here is a robust script for profiling an executable in Visual Studio 2012 Exclusive Mode using both tools.

2. Visual Studio 2012 "Exclusive" Behavior

Why does this behavior seem specific or "exclusive" to Visual Studio 2012? vsprecleanvsexe visual studio 2012 exclusive

A. The MSBuild Transition Visual Studio 2012 was the transition point where the build system moved heavily toward out-of-process builds. In older versions (like VS2008 or VS2010), clean operations were often handled more synchronously within the devenv.exe process. In VS2012, the IDE offloads this work to MSBuild nodes. This makes the clean operation feel like a separate background tool is running.

B. The "Clean" Bug Visual Studio 2012 had a known specific issue (distinct from later versions like 2015/2017) regarding the "Clean" command.

• The Issue: When running a "Clean Solution," VS2012 sometimes fails to delete files that are currently locked by the IDE (such as IntelliSense databases or debugging .vshost.exe files).
• The Result: Users would see "Pre-Clean" errors in the Output window, stating that files could not be deleted. This gave the impression of a specific "Pre-Clean" executable failing, though it was actually the devenv.exe process conflicting with itself.

Purpose and Functionality

Without specific details on vsprecleanvsexe, it's challenging to provide an exact purpose. However, based on the name and common practices in Visual Studio development: The search query you've provided seems to relate

• It might be involved in cleaning up temporary or unnecessary files or configurations specifically related to Visual Studio projects.
• It could be a preparatory tool for setting up or resetting Visual Studio environments, especially in scenarios where exclusivity or specific version handling is needed.

Conclusion

vsexe.exe and vsprefixcleanup.exe serve two very different but complementary roles in Visual Studio 2012 performance profiling. vsexe.exe is your launcher; vsprefixcleanup.exe is your janitor.

In exclusive mode, they are not alternatives but partners. Running vsprefixcleanup.exe before vsexe.exe is the single most effective way to eliminate "profiler already attached" errors and ensure clean, reliable performance data.

Remember this golden rule for Visual Studio 2012 exclusive profiling: The Issue: When running a "Clean Solution," VS2012

Clean first, then launch. Clean again when finished.

By mastering these tools, you can resurrect and maintain legacy profiling pipelines that continue to deliver critical performance insights long after newer tools have moved on.
