I have blogengine running as an app within the main site, running in the same application pool, with asp.net 4.0
I had the same inheritance issues as described and there is some indication frm MS that you cant have apps
domains on different revs of asp.net
The only problem I am now seeing is that when I try to upload a new post it fails with this error:
Url : http://www.antiquewinetest.com/blog/admin/Pages/Add_entry.aspx
Raw Url : /blog/admin/Pages/Add_entry.aspx
Message : A potentially dangerous Request.Form value was detected from the client (ctl00$cphAdmin$txtContent$TinyMCE1$txtContent="
This looks like the asp.net defualt validation refusing to accept html content in a text box.
Has anyone fixed this?
