I’m migrating my app from Silverlight to UWP. At the same time, I’m changing from VS 2013 to VS 2015. It was a while since I worked with the app and noticed that there where a new version of AutoMapper available in Nuget Package Manager, but I couldn’t install it. I tried to find a solution on the Internet, but didn’t find any. After several hours of struggling, I managed to install it after removing the contents of both bin and obj folders from all projects in my solution. I tried several times to just remove from bin, but wasn’t enough.
