Within this segment, we're going to produce a basic repository sample. We’ll allow it to be very simple since this informative article is about Dapper.

Following the class creation, we can sign-up it as being a singleton services in the Startup class, Should you be making use of .NET5:

Obtain the entire implementation and find out how anything will work beneath the hood. Do not forget to star my GitHub repo if you find it useful!

Dapper.Web however provides major positive aspects, specifically in terms of functionality and Regulate. Will examine Dappet.Web in upcoming articles making an easy CRUD application and looking out at pros and CONS of it.

Needless to say execution of saved method is supported. Any on the described solutions will allow the execution of a stored method. All it’s desired is to omit
