Where to look at CTS in .NET Framework?

Question

.NET

Hello! Tell me where you can look at the Common Type System in the .NET Framework, in which file is it located? I read Richter and he writes that int is the same as System.Int32 located in the .NET Framework Class Library, so is CTS and FCL the same thing? Help me figure it out, I'm confused

Answer 1

int, string, float - aliases provided by the compiler for .NET types.
As if you had such an announcement in the file: using int = System.Int32;
You can see where everything is in the studio, right-click on the type name, "Go To Definition".
