ADO.NET vNext: Entity Data Model (EDM) Designer Prototype

Folks,

To aid brainstorming and to better understand typical developer scenarios, the ADO.NET team created an internal prototype of a designer to let developers model the ADO.NET vNext “Conceptual” layer.

If you recall, Pablo Castro demoed this prototype in this Channel 9 video and shortly after that we received many requests from users asking for this prototype so they could take it out for a test run. Based on the numerous requests received, we have decided to release the “ADO.NET vNext Entity Data Model Designer Prototype CTP” as an unsupported tool to showcase our upcoming ideas for ADO.NET vNext tooling.

You can download the Entity Data Model (EDM) Designer Prototype from here.

The designer in this CTP is an early prototype and only supports designing the “Conceptual” layer. The designer can also generate an Entity Data Model with 1:1 mappings from an existing database that you can use right away in your application while also graphically visualizing the “Conceptual” layer. Please take a look at the walkthroughs in the Overview document included with the EDM Designer prototype for more details.

Do take it out for a test drive and let us know what you think over at the ADO.NET vNext Technical Preview Forum on MSDN.

More ADO.NET vNext Resources:

• Pablo’s announcement about the ADO.NET vNext August CTP has tons of great information about this exciting new technology.
• Plenty more links to whitepapers, Chanel 9 videos, screencasts and blog posts from ADO.NET vNext reference page on the MSDN Data Developer Center.

Regards,

Sanjay Nagamangalam

  Another milestone in the ADO.NET vNext train -- the Entity Data Model designer prototype has just been pushed to the web. In earlier iterations I have seen, this tool was more stand alone applications, so it's good to see it...

  A post about the EDM Designer prototype is at http://oakleafblog.blogspot.com/2006/10/new-entity-data-model-grap_115999276623949030.html. The post raises some issues about the Designer's current limitations and LINQ to Entities' query performance with larger-than-usual entity sets from related tables. The original version of the post mentioned problems with 1:1 relations between columns of a single table, which was incorrect and has been removed from the item. Specifying a many-to-one relationship between the Northwind.Employees.ReportsTo and Northwind.Employees.EmployeeID columns solved the problem. --rj

  Is it possible to use this with Visual C# 2005 Express Edition? The MSI is not installing since I only have the express edition, and I was just wondering if it's possible to get around somehow? Thx.
