Hi everyone,
    I've the some annoyng problem....
Every time I have an upgrade to publish is a nightmare...

my "strange" WebUC is in the "admin" subfolder and in the bin folder I have the extra dll "App_Web_adminmenu.ascx.xxxxxx.dll" and it is the only dll that is named in this way.

I have found a solution that sometimes works...

After having built the solution, in the pre-compiled site the page that gives me the problem has:

<%@ Register Src="../admin/adminMenu.ascx" TagName="adminMenu" TagPrefix="uc2" %>

and the line that thrown the error:

<uc2:adminMenu ID="AdminMenu1" runat="server" />


The solution that sometimes work is to give to the UserControl ID the same name of the "TagName" or removing the ID; this pieces of code work:

<uc2:adminMenu ID="adminMenu" runat="server" />

OR

<uc2:adminMenu runat="server" />



I hope this workaround should work for you too..

Bye!

PS: SOrry for my bad english...
