I am using a Calendar Extender in my ASP.NET application (.NET 4.0) and it works fine on my local machine when debugging, but when I deploy the web site to the IIS 7 server, the calendar is displayed as transparent and doesn't seem to have any styling. You can still click things on it, but it doesn't display properly.
When trying to figure out the problem I found out that if I copy the AjaxControlToolkit.dll directly from my local bin folder to the server's bin folder, this fixes my problem. However, I would rather not have to do this copy every time I do a new build of the site. I've done a build using the Publish option (web deploy) as well as creating a Web Setup project to create a .msi and they both cause the issues I am having. If I just copy all the files manually from my local machine to the server, it works fine.
Any ideas?
