Working around the lack of dynamic DbProviderFactory loading in .NET Core

.NET Core and .NET Standard are missing the DbProviderFactories class which is used to dynamically load ADO.NET DbProviderFactory instances which in turn are used to gain access to the various ADO.NET intrinsic objects generically without requiring an explicit reference to the data access provider. In this post I describe why this can be a problem for libraries that use multiple data providers and show a workaround for loading a DbProviderFactory without taking an explict dependency on the provider assembly.
