C# 3.0: What I Want [C# 3.0: What I Want]

One thing I really wished was in C# 2.0 way to specify a method argument as "non-nullable". Not having to manually check arguments for null would be a big plus in reducing and simplifying code.

.NET Gurus: Pinning a delegate for P/Invoke [.NET Gurus: Pinning a delegate for P/Invoke]

I'm attempting to P/Invoke a C library. It requires me to pass a delegate which the library will store for later use.

Because I do not use this delegate later in managed code it gets collected. Easy enough to stop, but pinning it in one memory location is another story. Is this possible?

Memory manager problem? [Memory manager problem?]

Hey guys, there seems to be something horribly wrong with the Windows memory manager.

See this source: http://dev.int64.org/memory.c
It runs in 8sec on winxp, and 0.013sec in linux. Even with my 1.5GiB of ram I thought maybe it wasn't able to expand the memory each time but I made it use a fixed 10MiB heap it and performs just as bad. Any gurus care to comment?
