Is there a way to check if a file is in use?
...which is more typing. If you have a explicit interface you'd also have to cast. Finally you want to dispose ASAP, and the finally logic may have UI or any other long running actions that have little to do with calling IDispose. </rant>

It takes a schema name as parameter, or public if no parameter is given.

What do people find difficult about C pointers? [closed]
... left till someone tries to build a compiler.
"Memory is memory is memory" Casting just changes which versions of operators or how much room the compiler gives for a particular chunk of memory. You know you're dealing with this problem when people talk about "what (primitive) variable X really is".

Why can't C++ be parsed with a LR(1) parser?
...xed as:
int (MyClass::*)(char*) MethodPtr;
this being coherent with the cast operator (int (MyClass::*)(char*))
typedef int type, *type_ptr; could be forbidden too : one line per typedef. Thus it would become
typedef int type;
typedef int *type_ptr;

Copy constructor versus Clone()
... used. It also returns object, which is a pain, since it requires a lot of casting. (And though you specifically mentioned classes in the question, implementing ICloneable on a struct requires boxing.)
A copy constuctor also suffers from one of the problems with ICloneable. It isn't obvious whether...
Best way to compare two complex objects

When you override Object.Equals, you’re also expected to override Object.GetHashCode; I didn’t do so below for the sake of conciseness.
