Virtual Path Provider
I have been trying to find material reading on the Virtual Path Provider (VPP) feature of ASP.NET 2.0. So far I haven't found a lot. The whole concept is supercool. If you visit the new MSDN website, it is built on VPP. The cool thing about VPP is that all those pages that you see are not actual physical ASP.NET files, instead they are all coming from a backend database. The most important feature from a user stand point is that you can query a website through the url. Yes you heard me right. Type https://msdn2.microsoft.com/system.net and you will be redirected to the .NET libary's System.Net namespace homepage. You can do the same with any class in the framework. Try https://msdn2.microsoft.com/System.String. That is simply awesome.
