VS2010 add new file throws Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception

Question

In Visual Studio 2010, when I right click a project and choose Add new item, the cursor blinks for a second but nothing happens. If I go File > New > File, I get

Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception

in a dialog box and can't add a new file.

I have Devexpress project templates and when Googling this error, see a few issues related to their WPF components. I am also using Windows 8 release preview.

Answer 1

I have Windows azure tools for Microsoft VisulStudio 2013- v2.2 and Windows azure tools for Microsoft lightswitch VisulStudio 2013- v2.2.

I uninstall only Windows azure tools for microsoft lightswitch vs 2013 .

It's working fine...

Answer 2

I resolved it when checking the references of the project, for me it was Microsoft.Office.Interop.Excel and Microsoft.Office.Interop.Word which had a different version that when I start coding this project. When loading the old references, everything went smoothly.

Answer 3

In my case the resolution was to UNINSTALL the Windows Azure Tools for Visual Studio 2010 then I restarted the VS and the error gone straight away.
