I have an MVC 4 application on .NET 4.5.I have my application deployed on Azure cloud.
Up until yesterday I would make changed to my application, then check in to TFS, then my application would automatically get deployed on azure. And everything worked just fine.
But today, after I made some changes, the deployment failed with the following error message: "The application pool that you are trying to use has the 'managedRuntimeVersion' property set to 'v4.0'. This application requires 'v4.5'."
In the azure configuration management page I have .NET FRAMEWORK VERSION set to 4.5. Furthermore there is no option for 4.0, only 3.5 or 4.5. So this seems strange.
Any ideas what could cause the problem.
p.s. I only made small changes in my Views, I didn't add any libraries or anything like that.
It is not an error in your code/configuration. There was an error in TFS service and many people had the same issue. But now it should be fixed. You can find more information on this page:
