 The goal of this package is to simplify the [.NET SDK](https://github.com/getsentry/sentry-dotnet/) by leaving the messy `#ifdefs`, platform specific code (operating system, runtime, etc) out into its own library. It also helps by allowing us to share code between the [new .NET SDK](https://github.com/getsentry/sentry-dotnet/) and the [current .NET SDK](https://github.com/getsentry/raven-csharp/).
