Question

So I have this asp.net web application that I renamed.
I changed the assembly name, root namespace, changed all the aspx files Inherits lines to have the new name.
But for some reason it is still references the old assembly name. So the main page loads but there is a button that submits to pgRequest.aspx and I get this error in the event viewer.

Follow-up:
So I recreated the solution, project and did add existing item for all the forms.
I still get the issue.

Here is the code that submits from pgMain.aspx

        <form id="frmNew" name="frmNew" action="pgRequest.aspx" method="post" target="_blank">
            <input type="hidden" value="frmNew" name="hdnSource"><button id="cmdNewSubmit" name="cmdNewSubmit" type="submit" value="NEW"><IMG alt="Open Form" src="images/new.gif"><span class="button_message">Open New Form</span></button>
        </form>

Here is the error message from event viewer.

Found the problem.
While I changed the Inherits line of the page directive in the development source, it wasn’t changed on the deployed version I was testing with. Deploying the corrected aspx files solved the problem.
