Lowering in the C# Compiler

The C# Compiler take the code you write and "lowers" it down to a version of C# that the .NET 2.0 run time understands. This is because all new languages features we've got since C# 2.0 (or there about) have been implemented either as library function or via C# Lowering or both. In this video I give you some background information about the C# compiler, the RyuJIT JIT Compiler and the .NET run time to then go on to show you examples of Lowerings that take place in the new C# compiler so that you have a better/deeper understanding of what happens to the code you write. This knowledge can help you get to the root cause of excesive memory utilization and performance issues as well as give you deeper insight as to how to code in C#.
