The C# => operator defines lambda expressions and expression bodied members. Lambda expressions define a block of code used as data.
#define simply substitutes a name with its value. Furthermore, a #define'd constant may be used in the preprocessor: you can use it with #ifdef to do conditional compilation based on its value, or use the stringizing operator # to get a string with its value. And as the compiler knows...

You can control the visibility of common language runtime (CLR) types. When your assembly is referenced, you control whether types in the assembly are visible or not visible outside the assembly. publicindicates that a type is visible to any source file that contains a#usingdirective for the...
