@akoeplinger can't repro on macOS with gcc-9 or gcc-5 from brew. Let's keep it scoped to Ubuntu 16.04 for now.

```bash $ gcc testmono.c `pkg-config --libs --cflags mono-2` -fno-exceptions -fno-rtti cc1: warning: command line option ‘-fno-rtti’ is valid for C++/ObjC++ but not for C /usr/lib/pkgconfig/../../lib/libmono-2.0.so: undefined reference to `__cxa_end_catch' /usr/lib/pkgconfig/../../lib/libmono-2.0.so:...

@akoeplinger not sure it would be useful, but just wanted to remind, that this problem did not affect macOS for some reason on either Clang or GCC, so there seems...

I am unable to reproduce the issue in a small setup so far, but I collected debug logs. The most relevant part I see is: > Mono: DllImport attempting to...

Tried this, but got /'MyAttribute' is not an attribute class/ from Script# at the usage point

It still fails with ``` Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array. at Microsoft.CodeAnalysis.CommonCompiler.CreateAnalyzerConfigOptionsProvider(IEnumerable`1 syntaxTrees, ImmutableArray`1 sourceFileAnalyzerConfigOptions,...

IMHO, the best API is no API. E.g. process CIL directly or at very least LINQ expressions, and give derivatives back as CIL or LINQ expressions. Then something like https://github.com/nessos/GpuLinq...

@seesharper does your example not repro the issue? I am on Ubuntu 16.04 (this is the environment, that Azure ML Notebooks set up). I am actually running in interactive mode...

Also interested in this. Wanted to clarify if this question was left unanswered because the feature is not currently available (on Windows, it is done using `ffmpeg -f gdigrab -i...
