Create ADO.NET adaptor for SQLite

How to create a ADO.NET adaptor for SQLite (i.e. generate my own DLLs from SQLite C source code, instead of using other existing DLLs or NuGet to install SQLite.) I want to do it as a learning experience but find no instruction on google.

I will use C#.NET in WPF VS2015 on x64. Do I compile the source in VC++ as a DLL and then reference to it in a new solution ? Will the DLL be x86 and x64 compatible or do I generate two separate DLLs?
