## Blog Round up
* [.NET Core](https://devblogs.microsoft.com/dotnet/announcing-net-core-2-2-preview-3/)
* [ASP.NET Core](https://devblogs.microsoft.com/dotnet/asp-net-core-2-2-0-preview3-now-available/)
* [Entity Framework Core](https://devblogs.microsoft.com/dotnet/announcing-entity-framework-core-2-2-preview-3/)

The .NET Core SDK 2.2.100 Preview 3 includes .NET Core 2.2 Runtime Preview so downloading the runtime packages separately is not needed when installing the SDK. After installing the .NET Core SDK 2.2.100 Preview, the following command will show that you're running version `2.2.100-preview3-009430` of the tools.

`dotnet --version`
