I have a simple WebForms project on VisualStudio 2013 created with standard web project wizard. Recently, I ve installed VisualStudio 2015 and decided to upgrade. After upgrade, I ve run standard NuGet package restore, which went just fine.
To my surprise the project does not build. Error message is:
The type or namespace name 'FriendlyUrls' does not exist in the
I had a very similar problem some time ago, the project wont compile and packages aren't really restored.
That's because the nuget management system changed on VS2015 from MS-build restore to Automatic Package restore.
You can use the package console to install it, but is better to follow these instructions provided by nuget: Migrating to automatic restore.
