The are the current key points from the latest version
1. If you have a lot of stylecop issues in the current vs codepane and you rightclick and run stylecop the population of the task pane is now much much faster.
2. If you have a project/solution with many many cs files and many many partial classes it will create a very large working set. It basically keeps an object graph of all partial types found in order to check them on the 2nd pass. At the end of the analysis
they are cleared and the private bytes released.
3. When analysing a very large solution the private bytes does rise but it also releases much of this over time.
So, I'll do a release build of the latest 4.6 and post it over the weekend.
If anyone can help investigate whether there is a memory leak in either stylecop, msbuild, r# or vs2010 then please do so. Any that are found in stylecop I will fix as soon as possible but right now I don't know of any more.
I've also been using the Alpha since it was released, and haven't had any issues.
