[Cauldron.Interception.Fody] build error on Mac

[jessejiang0214]

I used VS for mac to build a custom interception project then I got this error Fody/Cauldron.Interception: Cauldron Interception v3.0.0.35 Fody/Cauldron.Interception: ----- Implementing decorator interceptors took 12.0541ms ----- Fody/Cauldron.Interception: Compiling custom interceptor: AddMethodsToClass.csx Fody/Cauldron.Interception:

I think something wrong with this line cscPath = Path.Combine(this.AddinDirectoryPath, "csc\csc.exe");

Hi,

The scripting feature is actually a Windows only thing. But I think this is a good opportunity to make this also works on Mac. I need your help here... If you type in csc in the console what version of the compiler is executed?

I think you can use Roslyn.

Yes that is a good idea, but it does not work. During build there is already a version of the roslyn library that is loaded. Referencing another version in the Fody extension causes a loading exception. So I have to actually reference exactly the same version. Thats means that if the roslyn version in VS is updated my Fody extension won’t work anymore. I already tried with CSScript which has 3 different options Mono, classic and Roslyn. The roslyn does not work because of the reason above. The mono version was not able to compile my lambda-heavy scripts. The classic one seems to be an old version of csc. I also tried dotnet script, but since it is using roslyn I ran into the same problem described above. Another option I haven’t looked into is dynamically loading the roslyn library.

I am switching the script engine to CSScript… http://www.csscript.net/ This should solve the problem. But it also means no C# 6 features.
