    I'm using Unity 2018.1.3 and the issue is still there... I tried deleted all visual studio files, and nothing changed...

    I had the same problem (Unity 2018.1 - VS2017 - 15.5.1), Re-importing all assets did not help for me.

    I had switched the Scripting Running version from '.NET 3.5x equivalent' to .'NET 4.x equivalent' because i thought the newer the better. That's when the crashing of unity began. When i switched it back my problem was fixed.

    File\Build Settings\Player Settings\Other Settings\Scripting Running version\.NET 3.5x equivalent

    I hope it will help you to.

    Fixed in unity 2017.3? You're kidding right?

    I get unity editor crashes intermediately, when Visual Studio is stopped at a breakpoints and I hover my mouse cursor over a variable at the break point.

    I have re-sharper installed and have turned off all re-sharper debugging integration, which I was told by Unity support to do, but the crash still happens.

    When it DOES happen, I have to delete ALL Visual Studio files within the unity project folder and the "assetDatabase3" file, within the project library file, before I can get Visual Studio working again. If I do not do this, as soon as I land on ANY break-point... Unity crashes!

    It works a little bit better for me. I can connect the debugger, run unity, and it will hit most of my breakpoints. If I leave the debugger connected, I can work for quite a while before it crashes. If I stop the debugger, Unity will freeze every time.

    I have seen this behavior consistently across a few different projects. Is this a Unity problem, or a VSCode problem?

    Visual Studio was working perfectly with the debugger.... until it decided it didn't want to start at all on my Mac.

    Unity still crashes with VS - version 15.4.3. I can step through a few lines of code, then unity and vs stop working.
