    BTW, a few folks claim that Dapper's faster than EF6 - so I guess there's that.

    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.

          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.

            I haven't used it, but I understand that there is an article in next month's MSDN Magazine about it (should be on the site on Monday). Julie Lerman (she of much EF writing) liked it.

              I've used it a lot. It's excellent, but in large projects its best used with some form of POCO-generator such as Codesmith to auto-generate your DAL classes on your build server. Dapper is very fast and, even more importantly IMO, it doesn't get in your way.

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

                                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[^]

                                    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.

                                        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[^]

                                        I see that. Interesting. Thanks for the info.

                                          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..
