How can I programmatically generate Entity Framework classes from a database?

Question

How can I programmatically generate Entity Framework classes from a database and then automatically compile them?

I'm looking for a solution that takes a simple connection string and generates a C# library. Exactly what Visual Studio's entity designer does but programmatically.

Did you find any ways to generate EF classes in database-first applications? After years actually! — The Real Codeslinger

You are looking for Entity Framework power tools.

With that you can create a code first database from a connectionstring (Reverse Engineer Code First ).

With Reverse Engineer Code First you get the code first classes + mapping classes. You can even modify the templates used for the process. All the information you need can be found in the above link.

This looks really good but it's a visual studio extension. Is there any way to Reverse Engineer Code First programmatically?

Not that I know. But why programmatically if I may ask? This is something you do once. What is your goal? Creating a tool that does this?

It looks like this visual studio extension is open source. So this is exactly what I need. Thanks!
