I have just upgraded my Microsoft Visual Studio 2010 C#.NET application and Azure project to Visual Studio 2012. My project includes the Ajax Control Toolkit and I am using the Masked Edit extender for a number of textboxes and also the Calendar control for date input. As part of this, I upgraded to the latest version (v4.1.7.725) of the Ajax Control Toolkit using NuGet.
Everything is working fine locally, both running the project in debug mode and using the Azure Compute emulator. However, when I deploy my project to Windows Azure, the Masked Edit extender and Calendar controls completely refuse to work - it is as if they are not there. No error messages are displayed.
In order to to fix this, I have tried the following:
1) Ensure the "Copy Local" property of the AjaxControlToolkit assembly is set to True
2) Changed the ServiceConfiguration.Cloud.csfg to set the Azure Server OS to Windows Server 2012 using the osFamily="3" attribute of the ServiceConfiguration tag.
3) Opened the <application>.Azure.cspkg file using winzip to ensure that it contains the correct version of AjaxControlToolkit.dll for deployment to my Azure instance (it does).
None of these resolved the problem.
It would be interesting to know if anyone else has experienced this problem and if there is any possibility of a fix.
