I noticed that MSDN finally has nice URLs for the BCL. (Or perhaps that should be "I finally noticed that ...", depending on how long this has been)

So instead of:

http://msdn.microsoft.com/en-us/library/1009fa28.aspx

You can do:

http://msdn.microsoft.com/en-us/library/system.reflection.assembly.loadfrom.aspx

For overloaded methods, it takes you to the disambiguation page.

This actually makes it a lot easier to find BCL APIs when you know the name. Now most of the time, I can just type the name right into the URL. And I have a higher confidence that this link won't get broken.
