Because I don't like to wait I made a patch to speedup the "compile -> iis reload" feedback cycle.

By strong signing all the dotnetnuke assemblies and loading the module in the assembly cache I now only have to recycle the IIS application pool to reload the module.

I have to point out that this "patch" is only meant for module development and not production usage.

This patch is meant for DotNetNuke 4.7

I deleted the openid and liveid providers and had the bare minimum plugins installed.

I did some minimal benchmarks and my "load time" went from to 15 seconds to 4 seconds.
On another machine the "load time" went from 13 to 3 seconds.

If there is some interrest in this then I am willing to put much more information on this online.

hints:

Reloading the iis application pool: cscript c:\windows\system32\iisapp.vbs /a PoolName /r
replace PoolName with your application pool name

Be warned it's experimental it may kill you're cat or eat your computer.
