My program hangs when it gets values using Entity Framework. Here is my simple code:
LearningEnglishEntities db2 = new LearningEnglishEntities();
List<tb_Words> searchedItems = db2.tb_Words.ToList(); // it hangs here
It's not an async method. There are solutions about async
but I didn't find any solution to fix my problem.
It doesn't respond, it's waiting forever. All my code was running until 2 days ago. I didn't type or do anything and this bug happened (short video is here )
I have tried these things so far:
I removed Entity Framework model from my solution and I added it again
I created a new program and I used exactly same codes and model (it worked):
LearningEnglishEntities1 db = new LearningEnglishEntities1(); List<tb_Words> sample = db.tb_Words.ToList(); // It worked
I cleaned my solution
I typed this code:
var query = from item in db.tb_Words select item; // It hangs the same way
I checked this code is not run by another thread:
bool query0 = this.InvokeRequired; if (!query0) { LearningEnglishEntities db2 = new LearningEnglishEntities(); List<tb_Words> searchedItems = db2.tb_Words.ToList(); // It still hangs }
I changed my Entity Framework 6.0x version to 5.0x but it didn't work.
I completely copied all files and pasted to a new project. It ran but it didn't work
I restarted Microsoft Distributed Transaction Coordinator Service and checked startup type is Automatically. It didn't work.
Strangely, it works on other projects but it hangs on this project. I haven't found any solution to fix this bug. Do you think what should i do?
Also My Connection String is :
<connectionStrings><add name="LearningEnglishEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=DESKTOP-REKGVD4\SQLEXPRESS;initial catalog=LearningEnglish;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework"" providerName="System.Data.EntityClient" /></connectionStrings>
Thank you
After all things, I was able to find a solution but I don't know the reason. Using Entity Framework Code First solved my problem. It is not good for my project but i have to use it.
