By using Dapper, we can write SQL statements as we like to do in the SQL Server. Dapper has great performance because it doesn’t translate queries that we write in .NET to SQL. It is important to know that Dapper is SQL Injection safe because we can use parameterized queries, and that’s something we should always do. One more important thing is that Dapper supports multiple database providers. It extends ADO.NET’s IDbConnection and provides useful extension methods to query our database. Of course, we have to write queries compatible with our database provider. When we talk about these extension methods, we have to say that Dapper supports both synchronous and asynchronous method executions. In this video, we are going to use the asynchronous version of those methods. So, let’s learn more about these extension methods. To do that, let’s visit our article… We can see that Dapper extends the IDbConnection interface with several methods: Execute, Query, QueryFirst, QueryFirstOrDefault, QuerySingle, QuerySingleOrDefault, and QueryMultiple. Also, we can see that all of these methods come with the async functionality: ExecuteAsync, QueryAsync, QueryFirstAsync, and so on. Of course, you can see from the description what each method does, and by looking at that we can see that some of them are pretty similar to the LINQ methods ( First, FirstOrDefault, Single, SingleOrDefault).
