@SEJeff Exactly, what I just wanted to post! I think SEJeff agrees with me, when I say that people in that business have no mercy, be prepared and learn yourself before accepting raw advices. Question what we say too.

Net and low-level code... well only if they have a fpga-cluster running the .Net code through a specialized compiler like http://www.mono-project.com/Mono_LLVM and then run some commercial optimizers to tune the assembly. Even then, the risk of malfunction due to "undefined behaviour" is too high to take the risk. You're better of with just Ada,Fortran,C or C++ Backends

This is just to illustrate how ridiculous a .Net ultra-low latency trading system sounds.
