Steps to reproduce:
1. Download FarmManagementGame.zip project and open
2. Set up a breakpoint in GrowingState.cs at line 30
3. Attach to Unity and press play

    EDIT 15.4 preview build only partly resolves the issue, I can see that the debugger attaches properly and will break in some code. However, the instant I call into an external library, Unity crashes.

    FIXED

    Updating to Visual Studio 15.4 preview build resolves this issue.

    Attempted to use VS2015 with VS tools for unity. Attempted steps:

    1) Attach to Unity
    2) Set breakpoint
    3) Run game
    Result: Breakpoint is never hit

    1) Attach to Unity
    2) Run game
    3) Set breakpoint
    Result: Unity Editor crashes when breakpoint is hit.

    So it seems to matter when you put the breakpoint.

    I have this as well. 100% consistent silent unity crash when using VS2017 and hitting a breakpoint.

    There is a dupe of this here: https://issuetracker.unity3d.com/issues/unity-crashes-when-debugging-with-vs2017-when-using-net-4-dot-6
