[Fixed in R# 10.0.1] VS hangs on debugging MSTest unit tests

It happens due to https://youtrack.jetbrains.com/issue/RSRP-449577 exception

You may check that you experience exactly the same issue - please run Visual Studio with R# logging ('devenv /ReSharper.LogFile C:\log\resharper_log.txt /ReSharper.LogLevel Verbose') and then reproduce the VS hang, then check resharper_log.txt file - there should be "The dispatcher queue size on thread <NULL>:1 has reached the limit of 10,000 items." exceptions.

    I came here hoping for an explanation, a plan, a hotfix, something more than acknowledgement that it exists. There's been a ton of problems on my machines with R# 10, I've submitted probably 8 different exceptions since R#10 was released but there doesn't seem to be any feedback that the issues are being looked at or addressed. This being probably the worst since the test runner is useless now.

    Mark, a bug fix that addresses most critical unit test runner bugs (including the one described here and also the empty Output window) is expected later this week. Meanwhile, if you're a heavy unit test runner user, your best pick could be to revert to ReSharper 9.2 (you can get a link to 9.2 in this article: http://resharper-support.jetbrains.com/hc/en-us/articles/206104048-Where-can-I-download-an-old-previous-ReSharper-version-).

    Apologies for causing this issue.

    :-( Reverting back to 9.2... very disappointing, but looking forward to the fix.

    Martijn, we're finalizing fixes right now. Doesn't look like we can release today but I'm really hoping for the bugfix to be ready on Monday.

    Thanks for your patience.

    Looking forward to having my Unit Tests back... In the meanwhile, I'm (gasp) disabling Resharper :-(

    Debugging unit tests using plain old MSTest (using the Test Explorer to filter a bit) still works. Not pretty, but a better workaround than life without R# ;)

    I've resorted to:

    Write code
    Tools | Options | Resharper | Suspend Now
    Run unit tests
    Tools | Options | Resharper | Activate

    Looking forward to today's bugfix release, @Jura!

    NOT FIXED YET.... (at least for me) I downloaded and installed 10.0.1, and restarted, and I got the same error again. For all unit tests, when I attempt to ru nthem the message flickers to "Pending" in green for a split second, then changes to Orange message "Inconclusive Test Not run".
    I am running in VS 20015 with NUnit 2.6.4.

    Charles, is doesn't really look like the problem you're having is the same as the one described in this article.

    I can confirm it is fixed. I can debug MS unit tests again without VS hanging.

    Thanks guys!

    @charles bretana You experience a different problem, since VS does not hang completely in your case. As far as I understand from the issue description you mentioned -you face the following issue https://youtrack.jetbrains.com/issue/RSRP-450410. Please check that app config in the project contains external configs.
