I am trying to use dapper-dot-net to speed up some area of my asp.net mvc application. I am using EF5 Code first also.

Since dapper-dot-net is just some extensions for IDbConnection, can i just use

DbContext.Database.Connection 

to use dapper-dot-net? I test it is working. However, i am not sure this is the right way to use it? Especially, when I use that way, will Entity Framework still has some impact that could hurt the performance?

Using Dapper could be a significant performance improvement in certain scenarios.

You can share the EF connection with Dapper. However (although unlikely to be a problem) you should be mindful of concurrency issues (e.g. due to attempts to associate multiple data readers with the same connection).

If you do run into such issues, you have the option of giving a new connection to Dapper using the connection string (DbContext.Database.Connection.ConnectionString), instead of sharing the connection.

Can I use dapper-dot-net with Entity Framework?, Take advantage of the lightweight, open source Dapper to simplify data access and ensure high Dapper is an open source, lightweight ORM developed by the Stack Overflow team. Dapper is Net Framework and . If you have NuGet installed, you can install Dapper using NuGet—just select the project. I am using EF5 Code first also.

Yes, you can use it that way. Since Dapper is just working on extension methods, you can use it for the performance-sensitive areas of your code. And you can continue to use EF for other areas of your code. The queries that you have that are still using EF will not be as fast - but at least the queries using Dapper will be faster.

How to use the Dapper ORM in C#, Entity Framework is fabulous but it does impose some overhead. Dapper describes itself as "micro-ORM" because it provides much less The simplest way to use Dapper is to pass an SQL statement or stored procedure  I am trying to use dapper-dot-net to speed up some area of my asp.net mvc application.

I think you have to rethink about the question. Increasing performance via changing the ORM is not a good technique. It is correct that dapper is faster and lighter than EF but this does not mean that to increase the speed of your application its better to use the dapper. EF is powerful enough to handle the whole data layer if you suffer from performance you have to introduce new feature like caching or no sql db.

you have to see that changing from EF to dapper how much will save time for you ? and how much speed can caching bring to your application.

and adding dapper has other expenses: how would you manage the transaction while you have to point of save and update how you are going to solve the roll back situation, what about the Unit of Work and Repository pattern.

These are the factor that you have to examine before deciding to go for Dapper.

Data Points, This project will involve us querying for data from a SQL database, We generally want to use Entity Framework for our ORM, but just a little  The core reason people tend to pick Dapper over something like Entity Framework is the control it affords. Under Dapper, gone are the days of using a long complex LINQ queries that generate ghastly SQL that would make any DBA shriek at first sight. Infact, with Dapper you know exactly what SQL is going to be executed…. because you wrote it.

High Performance Object-Oriented Data Access with Dapper , Let's see if we can determine whether Dapper or Entity Framework Core Dapper and EF Core are two of the primary ORMs in use in the .NET EF Core, on the other hand, is a full-fledged ORM with lots of cool features,  I'm using Entity Framework to SQL Azure and in one page of my application we show quite a bit of related data to the user. Can I use dapper-dot-net with Entity

Dapper vs Entity Framework vs ADO.NET Performance Benchmarking, Dapper is a micro ORM or it is a simple object mapper framework which helps to native query instead of using a full-fledged ORM tools like EntityFramework or a new Asp.Net MVC 5.0 project in Visual Studio 2015(You can also use Visual​  Analysis. As we can see in the data above Entity Framework is markedly slower than either ADO.NET or Dapper.NET, on the order of 3-10 times slower.. Let's be clear: the methodology used in this test had something to do with this, particularly the "Teams per Sport" query.

Dapper vs. EF Core - Which is Faster?, Today, we will learn about Micro ORM called Dapper. EF Core and Dapper are both great technologies, but choosing Dapper would be  dapper-identity. This sample application demonstrates how to use ASP.NET Core Identity with your own code instead of Entity Framework to handle data storage. Dapper. I used Dapper, the super lightweight micro-ORM from the brilliant folks at Stack Exchange, to access the underlying database.

  • While true, this is unlikely to be a problem in most scenarios - threading certainly is unlikely to be a factor, so that mainly leaves the risk of there being an open data-reader - that is pretty easy to spot (the error is not very subtle)
  • @MarcGravell I'll take your word for it :) But isn't it just safer to always give Dapper it's own connection (instead of using the EF one)? Or is there a disadvantage to doing so?
  • Based on hard experience, by "faster" we mean "two or three orders of magnitude faster". I had one highly optimized query in Entity Framework that took 10 minutes, after converting to Dapper, it took a fraction of a second to complete a query 20x the size and complexity: stackoverflow.com/questions/9350467/….
  • @Contango Was that with EF's AsNoTracking?
  • @Ian Warburton Not sure - but regardless, Dapper's performance leaves Entity Framework in the dust. Having said this, Dapper is mainly geared towards reading data, so if you want to write into a database, then I guess Entity Framework would work if one is happy with inefficient, mediocre performance that can support perhaps 10 simultaneous users.
  • @Contango Why only ten?
  • @Ian I've yet to see any examples of Entity Framework being anything less than 10x slower compared to a Data Access Layer designed to be fast and efficient (i.e. within 50% of the theoretical maximum speed of a reasonable SQL query on some given hardware, using your language of choice). It may do 10 or 50 users - but it would struggle with 100 and certainly couldn't do 1000 or 10000. When I'm talking about "users", I'm more implying simultaneous users that are putting some load on the database.
