+## Purpose
+This project aims to workaround certain Visual Studio based .NET Core tooling issues of the time of it's creation (January 2017):
+- .NET Core Performance profiling is not possible neither with Visual Studio nor with JetBrains profilers
+- JetBrains Unit Test explorer does not work with .NET Core projects
+
+## How does it work
+- By referencing .NET 4.5 dll-s created by net45 target's of ImageSharp projects. NOTE: These are not project references!
+- By including test classes (and utility classes) of the `ImageSharp.Tests` project using MSBUILD `<Link>`
+- Compiling `ImageSharp.Sandbox46` should trigger the compilation of ImageSharp subprojects using a manually defined solution dependencies
+
+## How to profile unit tests
