Just add the function, like EF 6 still got it to run queries against the database in an async way.
Here is an example:

Right now, DataServicesContext works with DevArt DataContext via reflection provider. That leads to incorrect NULL translation in IQueryable and as consequence - extreme complicated generated SQL.

Implementing native ODATA provider for DevArt DataContext would fix the problem.

Rather than generic "Error on executing DbCommand."

Currently table properties have an "Auto generated value" attribute that causes a sequence to be created in the database. An analogous attribute named "Unique value" that creates a unique constraint in the database would be very nice.

Samples of using LinqConnect in WPF and Web projects

Since we can connect to Oracle without using a TNSNAMES.ORA by fully specifing de DSN entry I think the connection interface should manage this by itself.
An example of a DSN-less connectionstring:

Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;

There are a number of online implementations of a BatchUpdate and BatchDelete extension methods that can be transferred.

Supporting PostgreSQL array data types in LinqConnect will give it a great advantage over other ORMs. For any DBA that has worked with PostgreSQL will know of the benefits of using array types. It would be great to be able to integrate this within our entity sets also for an easy work flow with all the benefits of using arrays.

MonoDevelop has a rapidly growing following of cross-platform developers. Absent is good Linq to MySQL, SQLite, etc.

A function would be great, where you can specify a server for Selects and a different server for inserts. For Balancing/tuning an application

When using WinRT/Metro it would be great to have a product that would do what Wcf RIA Services did for Silverlight (especially the tight coupling between the Server project and the Client project.)
Perfection would include EF code first and MvvM.

right-click on class and choose "update from database". that way we do not have to go throught very slow process of updating all classes from database.

Allow for custom datatypes /object to be used in your code. Specifically for procedures and functions as both input and output

Integrate the product into Visual C#/VB and Visual Web Development Express like it works on Visual Studio 2010 Professional (GUI interfaces, support for Database Exploerer,...)

In Windows Azure you need to catch certain exceptions that indicate that there is a transient failure and you should try again shortly (with a exponential back-off) when your application is using SQL Azure. The following link provides a detailed description:

http://windowsazurecat.com/2010/10/best-practices-for-handling-transient-conditions-in-sql-azure-client-applications/

Entity Framework 6 is apparently going to be able to automatically handle this, so the developer won't need to wrap all their database calls with code that handles these transient conditions. As a developer working on a app that will be deployed on Azure, I would really appreciate this feature in LinqConnect.

Like Entity Framework .Cache LINQ queries , allow making LINQ queries to LINQ to SQL entities already loaded into memory - either came from db or created in the client as if quering LINQ to Objects
