.NET Designs Repository Created

# .NET Designs Repository Created

## Summary

.NET designs now have a home on GitHub at [dotnet/designs](https://github.com/dotnet/designs). This repository and the process it uses is intended to be very similar to [dotnet/csharplang](https://github.com/dotnet/csharplang). We want to share .NET design documents and get much earlier feedback on plans.

## Details

The repository was just created. You can see two designs that you can participate on. More designs will show up over time. These two designs were selected as the initial set since the current behavior for both has received significant feedback.

- [.NET Core 2+ Naming and Versioning](https://github.com/dotnet/designs/issues/2)
- [.NET Core 2+ Version Binding](https://github.com/dotnet/designs/issues/3)

A separate repository was created for a few reasons:

- .NET designs may need to be implemented in multiple repos, including runtime, framework and language repos.
- .NET designs may or may not be specific to .NET Core.

Thanks in advance for your participation in this repository.
