Swagger is the favorite API screening Software for practically every developer. It makes your lifetime really easy. Let’s include swagger to our WebApi and exam our implementation to date.
Internet applications, specializing in raw performance though keeping the simplicity of one's code. Dapper extends the IDbConnection interface with supplemental ways to perform SQL commands and question info.
As you are able to see, once we halt employing our connection, we must eliminate it.

Inside of a former case in point, we used two SQL statements to return two results and after that join them together in a single item. But commonly, for these kinds of queries, we don’t want to put in writing two SQL statements.
So what will take place is, we outline the interfaces for Repositories in this article, and apply these interfaces at Yet another layer that is definitely associated with Info accessibility, within our situation, Dapper.
