PostSharp 5.1 will focus on providing support for .NET Standard 2.0 and .NET Core 2.0. Our objective is to port the PostSharp compiler itself to .NET Standard 2.0 so that we can compile .NET Standard and .NET Core applications natively, without cross-compilation. PostSharp 5.1 will still only support Windows as the only build platform. 

Today we are releasing the final version of Entity Framework Core 2.0, alongside .NET Core 2.0 and ASP.NET Core 2.0.

Entity Framework (EF) Core is the lightweight, extensible, and cross-platform version of Entity Framework, the popular Object/Relational Mapping (O/RM) framework for .NET.
