Entity Framework Feature Suggestions

Welcome! You can use this site to tell the Entity Framework Team what features you want to see in future versions of our products.

Note that moving forward our team will be only fixing bugs, implementing small improvements, and accepting community contributions in the EF6 codebase. Larger feature work and innovation will happen in the EF Core codebase.

Please consider other options besides this site!

  • If you have technical questions or need help, try StackOverflow (EF6 and EF Core) or visit our forums.
  • If you want to learn how to use our products, visit our documentation pages.
  • If you want to report bugs or make contributions, visit our project pages on GitHub: EF6 and EF Core.

How can we improve Entity Framework or Entity Framework Core?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. Query only columns that needed

    Now days speed and resource usage became crucial in application development. This in mind I would like to see a future in EF where you can query only the fields you need not the entire object(table). Similarly having ability to choose table columns at the design time for database first approach.

        • Better match to SQL querying power and control over loading data

          I believe Linq to SQL and EF need to step forward in terms of giving power to developers to perform object-oriented queries against database. Many developers find it difficult to work with Linq to SQL because it is a world-away from T-SQL, also EF does not provide a way to query individual fields from database which has huge performance drain. I think the SF team needs to check out Salesforce SOQL. It puts a lot of power in developer's hand and yet it is very similar to T-SQL.

            • Specify which entity has the missing column

              It would speed development if the entity that has the missing column is provided to the user. Thanks

              • Support for Enums with Strange Names

                Support for Enumerations that use string fields would be outstanding, kind of like you can do in Visual Basic with Enum.["String Name"]. This would add a lot of flexibility.

                • Support for multiple result sets in .ExecuteFunction() / .ExecuteQuery()

                  A few overload methods can be added, for example:

                  public Tuple<T1, T2> ExecuteQuery<T1, T2>(string query) { ... }
                  public Tuple<T1, T2, T3> ExecuteQuery<T1, T2, T3>(string query) { ... }
