Thank you for your interest in this project!
I will be the mentor for this project for GSoC 2016. Please share your draft proposal through the GSoC process so that I can give you feedback. Note that student application deadline is March 25th 19:00 UTC.
For a little more background on the project, we've previously done such work for our Java code (Checkstyle in
REEF-332 and Findbugs in REEF-755, REEF-768 and REEF-789) and for StyleCop for .NET code (REEF-377). This project would be similar: enable FxCop in warning mode, go through the warnings it produces and fix them, enforce corresponding rules so that no new violations are introduced in new code.
