Test Runner - Visual Studio hangs when many files should be updated

created 8 years ago

I was happy to see that CodeRush for Roslyn finally left the beta phase and ended up on my download page. So I uninstalled CodeRush "Classic" to replace it with CRR on one of my machines (where I only do C# with VS2015).
While startup and interaction seemed a lot snappier and quicker than before, there is one major issue I keep hitting:

I use Git for source control, and I mainly work from command line (no Visual Studio plugins or anything). After switching between branches (using "git checkout the-other-branch"), VS mostly tells me that the project files changed and that it has to reload (with the big dialog that has "Reload All", "Reload", "Ignore All", "Ignore" buttons). Hitting "Reload All" does what I expected from Visual Studio (ie. reloading the changed projects), but compared to CR Classic and Visual Studio with CRR disabled, it spikes to 100% CPU and stays there for a couple of minutes, only showing the "Visual Studio is currently busy" popup.
Disabling CRR gets the old behavior back, so I thought I'd report it over here first before going to Microsofts' Connect (should it be Roslyn related).

The Solutions in question are average size I guess, with 15 projects (7 of which are test projects), about 7k files and a total of 500k LOC (counting everything, not just actual source).
The machine running this is an Intel Core i7 6700 with 32 GB RAM and both Solutions and Visual Studio/CRR on an SSD.
On average, one or two of the projects have changed between branches due to other developers adding/removing files.
