Migrate from Entity Framework 4.1 to 6.1

Question

User-1188570427 posted

I downloaded the Entity Framework from NuGet, but the option I am going by doesn't come up for me.  

Any ideas why?

I am looking for "EF Designer from Database" - http://www.exceptionnotfound.net/entity-framework-for-beginners-creating-a-database-first-model/

The only option that comes up is "Generate from database"

Also, I don't want to do code first. I've never understood the point of it. I have my database set up like I need and want to pull from there.

Hi tvb2727，

The only option that comes up is "Generate from database"

After choosing "Generate from database" , you could select the connection to the database you created and choose database object to include in your model . Please refer to links below for detail steps:

Yes, but how do I know it is using the EntityFramework.dll now compared to the System.Data.Entity?  The reason I want to use the new one EntityFramework 6.1 is because I want to use the .ToString() functionality in my LINQ queries.

Hi ,

Then have you upgraded to EF 6？In previous versions of EF the code was split between core libraries (primarily System.Data.Entity.dll) shipped as part of the .NET Framework and out-of-band (OOB) libraries (primarily EntityFramework.dll) shipped in a NuGet package. EF6 takes the code from the core libraries and incorporates it into the OOB libraries .Please refer to link below for upgrading to EF6:
