Support for command line parameters for automatic code generation from the model and automatic model generation from the database.

Code completion, syntax highlighting, code formatting, etc.

Templates for generating RIA domain model classes for Devart LINQ and NHibernate models.

Information here: http://www.linqpad.net/DataContextPlugin.pdf

Allow to define DDL Generation Template property to "Devart SSDLToOracle.tt" (or some other template) in an EDMX model and that generates database type automatically from an SQL Server model to Oracle (or 1.vice versa) as explained at this thread:

I am editing the EDML visually in Entity Developer and textually in Notepad++. It would be nice to be able to toggle back and forth in ED to edit the XML. Especially when updating the model when a table has changed or when doing Find and Replace, e.g. False => false, Double to Decimal, or changing Widget to Spanner.

Execution of native SQL code.

Ensure that Entity Developer and IdeaBlade DevForce work seamlessly with each other. Working with them so they support EDML in the DevForce Mapper, and making sure that changes to the EDML by their mapper are seamless in the DevArt model projects.

Model editing via C# or Visual Basic script.

Firebird database has support for .NET for over 5 years and I believe that it is very perspective database with very wide community and support.

Model should be DB-agnostic. One or more DB connections to a specific DB can be defined. These could be used for synchronization, XML mapping file generation etc. when requested by user. This way, a single model is maintained for more than one DB types. Now, there is not a simple way to accomplish this.

I don't know if this is even possible, but we have numerous users across the globe with small network pipes and access is very slow. (Yes, we have eliminated all unnecessary data). It would be nice if the data was sent compressed.

Support for third-party ADO.NET data providers in Entity Framework and NHibernate models. Provider should support Entity Framework for Entity Framework models.

Diagram for displaying storage schema

Some databases are so large, what it is too difficult to find your objects.
Or, for example, you develop some extensions for MySQL-based CMS and you wont to see only your objects.
Possibility to add filter (like in SQL Server Management Studio) would be very helpfull.

Add multiselect of Store objects to allow for changing the schema for all tables at once.

An additional template for generating DTOs for use in services where Self Tracking POCO entities are insufficient. Perhaps with some sort of repository implementation for converting the DTOs to "true" POCO's in the same template.

Migrating models between different ORM solutions (from Entity Framework or LINQ to NHibernate, etc.).

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;
