I am building this specific version, because it was the last version known to work on internet
on page http://blog.softelegance.com/net/setting-up-orchard-cms-on-mono/

I took sources of version 1.7.3 from sourceforge - here, and applied your patches here

After that I still have build errors, the log is here

Have you had any luck getting this to run using orchard 1.8?

Can login to Orchard with FF/Chrome, but not IE. Can browse ok in all browsers, just can not login with IE. It appears to login, but then bounce back to front page and not logged in.

Orchard/Mono (mod_mono) went unresponsive after a few days, apache barfed out::
