What's the strangest corner case you've seen in C# or .NET? [closed]

Answer 1

The scoping in c# is truly bizarre at times. Lets me give you one example:

if (true)
{
   OleDbCommand command = SQLServer.CreateCommand();
}

OleDbCommand command = SQLServer.CreateCommand();

This fails to compile, because command is redeclared? There are some interested guesswork as to why it works that way in this thread on stackoverflow and in my blog.
