Is C# easy to decompile?

C# is inherently easier to decompile into source code because it contains meta-data and most C# code must comply with a set of rules called “verifiable code”. Decompilers take advantage of the adherence to these rules along with attached metadata to make decompilation much better than equivalent C++ decompilers.
