So far a stored procedure cannot be mapped to an entity with complex properties. Well it can be mapped, but the execution fails at runtime. It would be great if we could map stored procedure columns to entity properties.

Provide Full-Text Search capabilities similar to Lucene.Net-NHibernate

LinqKit has shown that is possible to make the creation of queries much more dynamic, with them being composed at run time dependent on external conditions. nHibernate is good at this and LinqKit helps, but it would be nice to have an official solution.

Similar to adding support for stored procedures in Code First, but for functions also.

Using model first, this is supported and using EdmFunctionAttribute they can be used from LINQ to Entities. I really miss this in the Code First approach.

Currently this requires lots of ceremony setting up ILogger infrastructure as described in https://docs.microsoft.com/en-us/ef/core/miscellaneous/logging.

Need a new type of ClassDiagram tool for Code-First POCO classes which should be similar to Entity Designer, capable of showing relationships, keys, db schema related meta data etc.

Support for mapping System.IO.Stream to Binary fields

See http://www.pabich.eu/blog/archive/2012/05/16/Entity-Framework-migrations-donrsquot-support-parallel-development.aspx

When I do user.Cars.Add() EF load all Cars for that user.
user.Cars.Count() too

Currently, a discriminator column is only possible in TPH scenarios. The rational behind this is that in TPT the entity type can be inferred by joining. This is true but costly. In a serious application with many rows, the existence of a discriminator can have many benefits. For instance: one can create a composite index on the discriminator and primary key, on the base table (I could also use an index on primary key, filtered by the discriminator).

I would like EF to support sqlvariant columns like Linq to SQL does

I would like the option to detach an entire loaded object graph easily using the DbContext API. And to attach the graph again with several option for choosing if existing data should be overwritten or not.

Support Stored Procedure Return Values, output parameters of any type and procedures that don't return a result set, like an update statement.

It would be very nice to be able to support properties which are collections of value types. Just to have an array of doubles I shouldn't need to map each value to a class. NHibernate has this feature. E.g.
class Benchmark
{
public long Id {get; set;}
public string Name {get; set;}
public IDictionary<DateTime, double> Returns {get; set;}
public int[] Vector {get; set;} // preserve the order too
}

want to use the entity framework. However I also have the requirement of allowing my users to define custom fields in our system. I would like to still use the entity framework and not use a a partial class with a hash table property.

Now that EF 5 supports enums, please (optionally) create Lookup Tables in the database with the enum items or store them in the metadata.

This enables Lightswitch and other apps to reconstruct the enums/use the Lookup Tables.

We need an easy way to give the user the "Cancel" functionallity when he make changes to entities data but he does not want to save changes pressing Cancel button. I think adding DiscardChanges to ObjectContext is the solution, going back to its initial state and dissapearing added entities (even child entities) and returning modified or deleted entities to their original state

please add SQL Server 2012 features to new release of entity framework and code first that support filestream and filetable
