One of the more esoteric features of ASP.NET is its ability to run outside of IIS. Specifically, it supports a hosting framework (within the System.Web.Hosting namespace) that enables you to run it on top of other web servers, within command line exes, etc. The below sample demonstrates a simple way to process ASP.NET requests within a command line exe (MyHost.exe). When run, MyHost.exe spins of ASP.NET (threadpool and all) and interprets each parameter to the executable as a URL request to a local file. It then outputs the content back to the console window. To try this out, perform the following steps:

1) Copy The MyHost.cs and Test.aspx files to a local directory

2) Compile MyHost.exe by typing “csc MyHost.cs /r:System.Web.dll” within a command prompt in the directory

3) Type “MyHost.exe Test.aspx”

Hi, I had to copy the exe generated into a subdirectory called bin in order for this to work. Otherwise :
System.IO.FileNotFoundException: Could not load file or assembly 'MyHost.

Otherwise, excellent demo.

Here is another example using SimpleWorkerRequest:

Hi, I keep getting "Invalid URI" errors when I try your example on either WinXP or Win2000. I'm struggling to find any other examples similar to yours - can you please advise why I'm getting this error?
