+Intro to .NET Core

 For work that involves adding new APIs we'd like the issue to contain what we call a *speclet*. The speclet should provide a rough sketch of how the APIs are intended to be used, with sample code that shows typical scenarios. The goal isn't to be complete but rather to illustrate the direction so that readers can judge whether the proposal is sound. Here is [a good example](https://github.com/dotnet/corefx/issues/271).

 Coding Style Changes
 --------------------
 
 We intend to bring dotnet/corefx in to full conformance with the style guidelines described in [Coding Style](coding-style.md). We plan to do that with tooling, in a holistic way. In the meantime, please:
 
-* **DO NOT** send PRs for style changes. 
+* **DO NOT** send PRs for style changes.
 * **DO** give priority to the current style of the project or file you're changing even if it diverges from the general guidelines.

 To begin using the .NET Portability Analyzer, download the extension from the Visual Studio Gallery. You can configure it in Visual Studio via  *Tools* >> *Options* >> *.NET Portability Analyzer* and select your Target Platforms. For now, please use ASP.NET 5 as a proxy for all .NET Core 5-based platforms (e.g. [Windows 10 .NET UAP apps](http://blogs.windows.com/buildingapps/2015/03/02/a-first-look-at-the-windows-10-universal-app-platform/)).

 After running the analysis, you will see your .NET Portability Report. Only types that are unsupported by a target platform will appear in the list and you can review recommendations in the **Messages** tab in the **Error List**. You can also jump to problem areas directly from the **Messages** tab.
