Any F# coder here? I am having difficult times in backtesting from Visual Studio (2017 Community Edition). 

What is the bare minimum needed to run LEAN on my local machine? May I delete all Python projects? 

What is the recommended way of proceeding from the .NET API? Building DLLs from C# and then call them in F# or go F# all the way?

Once I understand the basics I am more than happy to contribute with the F# part.

Thanks for your help.
