In their reporting system. Earlier, I tried to load 100000+ entities on 30 columns using an EF. This lasted over 20 minutes. But after I tried BulkInsert, the insert operation took a matter of seconds. That was incredible.

First, thank you for your response. I am really really surprised with your Z.Entityframework.Extension. It's super amazing.It helps me a lot when I insert data, especially using Bulk Merge. The performance is very good and I love it.

I am astonished by the quality and the performance of the library. I was struggling in an online agent based simulation when trying to update 2M rows every minute using the default EFCore SaveChanges implementation. Installed the nugget package, read a little bit of documentation, and in less than 10 minutes, the problem was solved ! Dividing my update time by 5x !

2021-07-15: Adrian from Bluntt Internet Services
We, and the client, are overjoyed that by refactoring the code to use the extensions we were able to reduce the time required for the task from 90 minutes down to under 2 minutes and in the process making us look amazing good! Thank you!

Nothing can beat the performance of the BulkInsert, it is truly mind-blowing!

2021-05-15: Pablo from Diputación De Albacete
What can I say? Your library is simply amazing!

2021-04-15: John from Tonic
I refactored the code to use the BulkUpdate extension in your package, and the results were pretty awesome. The request went from taking 4 + minutes to 15 – 17 seconds!

2021-03-15: Cemil from Performans
It is remarkable. I can do more in less time!

2021-02-15: Grant from G.W.Consultancy
Very satisfied so far!

2021-01-15: Marc from UMC Utrecht
Great product, really adds value to .net core. Performance has jumped up significantly while using bulkInsert!

2020-12-15: Marcin from MMnet
We are testing EF extensions in a few of our projects, and it is much faster than using standard EF methods. We are very pleased with the evaluation result!

2020-11-15: Frank from Ronesoft Limited
I've been using two of your NuGet packages, the first being the System.Linq.Dynamic and Z.EntityFramework.Extensions.

The first package solved a thorny problem of dynamically setting search order, which is awesome. Saves a lot of extra code.

The second, we are primarily using to import a massive amount of records. Again a very thorny problem for our use.

I like to use Entity Framework Extensions because this framework gives me the possibility to save data faster than the normal Entity Framework.

2020-08-15: Wangke (Freelancer)
With your library, The bulk insert function is very convenient to use and does not require excessive changes and modifications.

2020-07-15: Marijan (Freelancer)
I'm very satisfied with your great product! It makes bulk operations so easy for me.

2020-06-15: Eirik from Escali Financial Systems AS
The framework has delivered what I needed.

2020-05-15: Cristian from Doc Flow
I must say that the library with Bulk methods is really fast compared to the good old SaveChanges!

2020-04-15: Hassan (Freelancer)
I love the extensions, and the gains are real. I recently tried out the Audit extension and found it very practical.

2020-03-15: Fredrik from Dentsu Aegis Network
The library is awesome, and had been a great help for our Project!

2020-02-15: Amin from (Freelancer)
I need to apply for some work on an entity without need to fetch it from the data source, and these extensions do that exactly as I expected.

2020-01-15: Emre from TDS-V
With your library, I can easily update and delete rows WITHOUT having to select them first + bulk insert many rows; That improved the performance greatly.

2019-12-15: Pavel from Binary Solution
With your library, I was able to load, change and save approximately 27000 records in less than 2 minutes. Without your library, it was an unrealizable task with a standard EF framework.

2019-11-15: Joseph from Rotageek
It's been very nice how we have been able to implement your product without having to make significant changes to our codebase.

Without EF Plus and EF Extensions Entity Framework would just be awful to work with. I'm so glad I ran across your company/software.
