SmallestDotNet - SmallestDotNet.com is a single page site that does one thing. It tells you the smallest, easiest download you'd need to get the .NET Framework on your system.
I can't find anything about 393292 but this page has 393273 as "4.6 RC". I have marked them as "4.6 RC1" and "4.6 RC2" respectively for lack of better information...
Cool, are we sure this is right? is this just another newer 4.6Preview, or is it 4.6RC?
