I've been trying to set up 1.90 on a web hosting package with EUKHOST. 1.80 works fine on it but I can't get 1.90 working. I've so far had to remove a couple of lines from the web.config to get it to get anywhere. Now, I get this:
"Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded."
It's getting frustrating.
