    Does anyone here use the Dapper ORM?

    I've used Dapper a few times. I really like it and as others have said it generally gets out of the way and works well at mapping your sql to an object or collection of objects. I use it with Dapper extensions which makes simple selecting/updating etc pretty simple. I invested a lot of time in learning EF and it was hard to make the move but honestly I've never found a need to go back to using EF. EF seems overly complex, at least for my needs and I fail to see a good reason for using EF over a micro orm like Dapper or PetaPoco (which i also like).

      C# is simply a copy of java, but without the cross-platform capabilities.

          I use edlin to edit my code, and manually compile everything (yeah it takes a lot longer, but it's hella efficient code).

                  I use it. We wrote a slightly bigger ORM thing to go on top of it: Dashing[^] And yes, much time was spent on the name.

                    I have heard of Dapper, and that is about all. I have the most experience with EF but I am not going on the record to say that it is the best. I'm sure there are applications best suited for Dapper. I found this to be interesting. The conclusion at the end is the most important. Dapper looks to be faster in a lot of respects. Interesting. Don't Panic Labs – Speed Comparison: Dapper vs Entity Framework[^] Looks like Stackoverflow uses Dapper.

                    Dapper is considerably faster than EF. And I also believe that it was written BY Stackoverflow. GitHub - StackExchange/dapper-dot-net: Dapper - a simple object mapper for .Net[^]

                      Dapper is written in C# which is from Microsoft too :-)

                        I've been using Dapper's spinoff NPoco for a couple of years in a large work project and it's worked out mostly great. The good: 1. Lightning fast, just a fraction slower than bare-bones ADO.NET. 2. No surprise SQL, you know exactly what SQL is sent to the server because you wrote it yourself (unless it's a simple single-table CRUD operation that NPoco generates itself). 3. Latest versions come with Linq expressions support. Back when our project got started there was no Linq support in NPoco and I ended up writing my own Linq-like repository wrapper. (I've made several other customizations to NPoco not all of which have made it into the official codebase, so I can't upgrade.) The bad: 1. No support for the JOIN syntax in NPoco's Linq implementation. Depending on how you look at it, this can be either a deficiency or a blessing (given how ugly SQL can get with auto-generated joins in EF and other full-feature ORMs). 2. The API can be a little confusing with too many overloaded methods and methods with different names but similar functionality.

                          Not that one, but I have used something called 'PetaPoco', which is kinda based on Dapper. The nice thing, to me, is it is a single .cs file that can be included right in you solution. He also has a later version that is a normal assembly. You will probably need to google 'PetaPoco' to find it.

                          NPoco is the latest version of PetaPoco and is still being actively maintained.

                              EF 6 has more optimizations than before, and is more powerful IMHO then 4 or 5. Any reason why you can't use that?

                              The biggest reason I use Dapper, sometimes I just want to create some POCOs and have them access the db. With Dapper all I need is a connection string and my classes..

                                I used it for a project. I didn't use any of the object-relational mapping, but I liked that I could swap this:

                                SqlConnection conn = new SqlConnection(connString);
                                string sql = @"select * from MyTable";
                                SqlCommand cmd = new SqlCommand(sql, conn);
                                conn.Open();
                                SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
                                if (rdr.HasRows)
                                {
                                while (rdr.Read())
                                {
                                //do something with record
                                }
                                rdr.Close();
                                }

                                with this:

                                SqlConnection conn = new SqlConnection(connString);
                                string sql = @"select * from MyTable";
                                IEnumerable flatResult = conn.Query(sql);

                                I thought that was pretty handy, especially for quick prototyping where the table and field names were changing a lot and I didn't want to hassle with altering all the field names and just wanted a quick resultset back.

                                  with this:

                                  SqlConnection conn = new SqlConnection(connString);
                                  string sql = @"select * from MyTable";
                                  IEnumerable flatResult = conn.Query(sql);

                                  I thought that was pretty handy, especially for quick prototyping where the table and field names were changing a lot and I didn't want to hassle with altering all the field names and just wanted a quick resultset back.

                                  Inline SQL for anything (C# code files, etc.) is strongly discouraged at our shop, but I see your point. :)
