    I needed this patch for a fix but now I can't debug anymore.

    I have VS tool 2.1.0.0

    Anyone have a workaround?

    Having the same problem in 5.2.1p2

    Also noticed the 'Select Default Editor' appears to be missing from Project Settings so I can't set my scripts to open in Mono either.

    I also have this problem. I submitted several bug reports with crash dumps (736495, 736117, 736035, 736026, 736021, 736015, 736011, 736000, 735792). Perhaps a tad overkill but I was told submitting the dumps is always a good idea.

    Tried 5.2.1p4, 5.2.1p2 and 5.3.0b2.

    A work-around for this issue is to use VSTU 2.0. We are still looking into this issue and will report back with an update once we found the root cause.

    The root cause of the issue has been found and fixed. Will update again once I know which release this fix will land in.

    The release process for it has been started, should be released this week unless there are some ship stoppers.

    You cannot download VSTU 2.0 from the official website, only the latest version. I do not recommend downloading it from other places.

    I'm afraid the issue is still present in Unity 5.2.2f1. I've uploaded a new crash dump (738250).

    Does this also happen for you on a new single script project? And do you know if you have this issue in MonoDevelop? The debugger clients in Visual Studio and MonoDevelop are different and therefore do not behave in the same way.

    The call-stack from your log is different than the issue that was fixed. Your call-stack seems to indicate that the debugger in Unity crashes when trying to retrieve the stack frames for a thread and it looks like a real and different bug. In order for us to be able to fix this issue you need to send in a project in which we can reproduce the crash.

    I've created a new bug report and attached a project which triggers the crash (fresh project, single script) a couple of hours ago. I've yet to receive the ID to give you for some reason, usually this happens within minutes. I'll post it once the bug report has been processed.

    We are unable to reproduce this issue, has VS debugging ever worked for you? For instance in VSTU 2.0? And could you try to attach with MonoDevelop and see if you get the same crash?

    I do not get this crash when using MonoDevelop.
    I've used the debugger quite a bit in the past with only the occasional crash here and there.
    If I enter play mode before attaching this works fine.
    I don't know where to get an installer for VSTU 2.0 otherwise I'd happily test it out.

    I will forward this issue to the VSTU team and maybe they will be able to reproduce and/or look into the issue.

    Interestingly the issue goes away if I use PC/Standalone instead of the WSA target. Thought I'd let you know.

    Got same issue on several versions of Unity. Right now I am on:


    Built from '5.3/release' branch; Version is '5.3.1f1 (cc9cbbcc37b4) revision 13409467'; Using compiler version '160040219'

    OS: 'Windows 10 (10.0.0) 64bit' Language: 'en' Physical Memory: 16288 MB

    When i put a break point on VS2015 with VSTU 2.1.0, then I play, the Unity Editor immediately crash and I can't find a way to restore it. Deleting the assembly, libraries, recompiling... nothing works.
    Then I start "debugging" with Debug.Log and forget VS. After a while the debugger seems to work again.
    I tried to find a logic relation in this but i got nothing more specific, sorry.

    This is the crash log:


    Unity Editor [version: Unity 5.3.1f1_cc9cbbcc37b4]



    KERNELBASE.dll caused an Access Violation (0xc0000005)

    @lukaszunity is this bug fixed for the QA team?
    I still can't debug anything done on the first frame because Unity crashes.
    Any help would be appreciated :)

    If you are still experiencing a crash, please file a bug report with a repro project.

    I filed a bug an got an answer from QA. You just need to turn off the experimental exceptions in the VS options.
    It is likely a new version of the VSTU will fix the issue.
