You will need to install the SL 2015 Software Development Kit (SDK). Part of that kit include the SDK Conversion tool that you can use to convert SL 2011 projects to SL 2015 projects. Once a project is converted, you open it with VS 2013 and execute the build process. One side note: depending on how your SL 2011 project was created, you may find you have around 102 errors when you open the project with VS 2013. If that is the case, open the code window and go to protect properties and change the target framework to .NET Framework 4. That should remove the errors.
