Starting from Visual Studio 2015, .NET Framework starts to become open source and cross-platform (!). Besides the newest features of probably the best known IDE, you will see how .NET Framework becomes widely available on Github and how much you can squeeze from .NET on Mac and Linux. We will also look how the most popular packages (like ASP.NET MVC and Entity Framework) try to fit to this announcement and say bye, bye to nightmares with .sln and .csproj files.
