Now it’s time to check our series of tutorials to make you find out Dapper and use it confidently within your .Web applications.
I imagine that this technique exists mainly for producing easier to adopt Dapper in legacy codebases the place instead of coping with strongly typed lists you may have to deal with a DataReader, and refactoring to use a typed record it is actually not possible. If that’s the case, then is the tactic for you personally. Given that the identify counsel it just returns a IDataReader.
