In order to narrow down the issue, can you please clarify the following:
- Does VS10 crashes on closing or sluggish if you run only one or two instances?
- In all the 8 instances of VS, different solution files are loaded?
- What is the OS and bitness you are using?
- what is the version of CodeXL you are using? is it 1.5?
I reinstalled CodeXL this morning briefly to answer your questions.
VS crashes on close (with a minidump and windows error reporting dialog) even with only a single instance running. I did not notice Visual Studio running slowly in the few minutes I had CodeXL installed today. I tried with just one solution and with all 8. It may take longer for the slowdown to build. When I was using it before, the slowdown was very significant.
7 have different solutions of one project each, one has a solution with all the other projects inside it. There are no warnings about files being locked by other instances of visual studio.
