dotnet/efcore ? reverse-engineered prompt

Build me a clean local setup for this .NET repository so I can clone it, build it, and run the tests without guessing what to do next.

I want the main EF Core pieces and the SQLite support library to compile successfully, with a simple first run path that shows the build and test commands I should use. If anything in the repo needs to be configured first, handle it in the project so it works out of the box as much as possible. Please make sure the solution opens and builds in a normal developer environment, and if there are any missing docs or scripts, add the smallest helpful ones so I can get started quickly.

If you need current setup details or command options, look them up online and keep the instructions up to date.
