Target runtime linux-x64 

options are selected and silnge file is not selected.

An unhandled exception occurred while processing the request.

If application is running from Visual Studio IDE developer page shows line numbers (49. in this sample) and source code lines in red:

c# on linux is the same as windows. to get line numbers it must be a debug build (otherwise they are optimized out). the .pdb file with optimized binary will allow looking at global symbols via the debugger. 

but you error look like it from a library doing a dynamic compile. you should check the documentation if it supports better compile errors.
