Forum Xamarin Xamarin.Android

Visual Studio for Mac crashes when building an Android Project (fatal error).

When I try to compile my Android project the IDE shows the following alert message, then it closes itself (without clicking the OK button). It happens either when I build for Debug or Release.

A fatal error has occurred
Details of this error have been automatically sent to Microsoft for analysis. Visual Studio will now close.

    It seems unable to compile Android Class Library projects. I created an empty project of this type and the Visual Studio crashed as well. msbuild also failed with the same exception.

    I fixed this issue downgrading Xamarin.Android. Now I can compile Android Class Libraries again.

    These are the commands I ran on OSX terminal:

    $ cd /Library/Frameworks/Xamarin.Android.framework/Versions
    $ ls
    [email protected] -> 8.3.0-19
    $ sudo rm Current
    $ sudo ln -s 8.2.0-16 Current
