I have a web site i created using VS2012 web edition,
Running a VB.net asp web site,
In the VS2012 debug/release mode it compiles and everything works good,
When i upload it to a server (Windows server 2008 R2) I get the following error:
The base class includes the field 'html', but its type (System.Web.UI.HtmlControls.HtmlElement) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlGenericControl). Line 2: Line 3: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Line 4: <html id="html" xmlns="http://www.w3.org/1999/xhtml" dir="ltr" runat="server"> Line 5: <head id="Head1" runat="server"> Line 6: <title></title>
I looked a bit on the web and found this :
VS 2010: Value of type ‘System.Web.UI.HtmlControls.HtmlGenericControl’ cannot be converted to ‘System.Web.UI.HtmlControls.HtmlTableRow’
Installed it but no help,
The site i created was re-created from another vb.net project so i used a web.config with from the old one, maybe it has something to do with it, i have no “assembly” properties it this XML.
Other pages that are not related to that master page (that html tag is running on a master page…) work’s fine.

So after trying a lot of stuff that didnt work i found a solution, i dont like this solution but it works,
I went to the
page.designer.vb file, and then looked for the ‘html’ and ‘Head1’ properties that were generated there,
In there i replaced their types to
Afterwards, it worked.
Weird bug, nothing else (including the “hot fixes” that are mentioned in other posts helped.
Hope this would help some one out there .
Somehow the designer file and the markup file get out of sync, even if the types appear to match.
I changed the ID attribute of the problematic control, saved, and rebuilt in the markup file. I then changed it back to the original ID, saved, and rebuilt.
Problem goes away!
Weird issue it is I am not sure if there is a proper solution for this but what worked for me was simply changing the Control ID. and then designer.cs file was changed and all worked good.
I fixed it by Cleaning Solution/project -> Rebuild
