ASP.Net error - type is not compatible with the type of control

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.

Solution

  • OK,

    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 System.Web.UI.HtmlControls.HtmlGenericControl

    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 .
