I have an ASP.NET application, which is using .NET framework 4.0 in Visual Studio 2010. Now I want to migrate it 4.5 in Visual Studio 2012. When I opened the entire solution in VS2012, the whole project migrated successfully along with the option of the backup.
But when I cleaned and rebuild the whole solution, I came across these errors. How can I resolve these errors?
