ADO.Net Entity Data Model

Question

ADO.Net Entity Data Model

Amit Patel 126

When I try to add the ADO.Net Entity Data Model into my project, I am getting the following message -

"The Project's target framework does not contain Entity Framework runtime assemblies. Please review the target's framework information in the project's property page."

I tried checking the properties of the Project, but could not found the framework information.

.NET 5.0 is .NET Core there is no EF Data Model available with EF Core. You want to use EF 6 and the Data Model you have to use .NET 4.8 or lower that I know about.

I'm looking at a TargetFramework of net6.0-windows. Would resetting this to net480 fix the issue? (looking at the csproj file)

You create a new project and there should be a drop down list that allows you to select the version of the .NET Framework you want to use for the project. If the version in not there that you want to use, it gives you an option to install the version you want to use.

Hi AmitPatel-5670,
As DuaneArnold-0443 said that EF Core does not support the EDMX file format for models.
And the best option to port these models, is to generate a new code-based model from the database for your application.
More details please refer to this document.
