I know this is a very special case but still i ran headlong into it.

The easiest way to implement a B+ tree on disk is using a memory mapped file. I think this is what SQL Server does, but don't quote me.

However, the only way you can access memory mapped files in C# is through .NET interop which makes it useless.

Because one of the points of a memory mapped file is that you can do memory allocations that are backed by disk.

There's no way in hell .NET can give you that in its current incarnation, even if one were to write a custom host, because of the way a GC system works.

What I'd like

var foo = new int[1000000]; // backed by disk, paged automatically

What I'd have to do.

somepointer = VirtualAlloc(...)
Write(somepointer, data)
etc
etc

basically it works like file i/o which defeats essentially the whole purpose.

=(
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.
