 A Serilog provider for [Microsoft.Extensions.Logging](https://www.nuget.org/packages/Microsoft.Extensions.Logging), the logging subsystem used by ASP.NET Core.

-### Instructions
+ASP.NET Core 2.0 applications should prefer [Serilog.AspNetCore](https://github.com/serilog/serilog-aspnetcore) and `UseSerilog()` instead.
