Thanks a lot! Please go on like this!!!

All great until minute 1:02:00. This line,
AddScoped<IProductRepo, ProductRepo>();
should not be set in API level since API has to be agnostic and independent from the Infrastructure. Imagine you want to switch from SQL to MongoDB. Now your API is stuck and cannot switch from PostgreSqlRepo to MongoRepo without changing that AddScoped line. SOLID violation there.
Everything else was great. Thanks.

Hi, can you share github link to the code.

Repository pattern is not viable... if i have a query that spans multiple tables there will always be diferent points of view to each repository should belong and if you add all repositories you can't have an optimized and elegant solution. Also EntityFramework loses a lot of power with it.
