Thanks for the feedback, Mark. When I have some spare time I will do some work to update this template for VS2010 so it will work with both EFv4 and EFv1 models. Good to know that I won’t need to do much.

I’ve trying to use this in the latest versions of Entity Framework and Visual Studio. Although I haven’t got a complex example to run against and test, It appears to work with VS2010 RC, Entity Framework 4 RC. You just need to update the namespaces…

XNamespace edmxns = “http://schemas.microsoft.com/ado/2008/10/edmx”;
XNamespace edmns = “http://schemas.microsoft.com/ado/2008/09/edm”;
XNamespace ssdlns = “http://schemas.microsoft.com/ado/2009/02/edm/ssdl”;

Thanks for this useful template

Hi David.
Thanks for such work, really saving a lot of time.

In VS 2008 sql Generation completed successfully!

But bugs when running your template under VS 2010 Beta 2

Soft:
Visual Studio 2010 Beta 2
T4 installed using VS Extension Manager

INPUT:
1)Generated model
2)Removed sysdiagrams
3)Rurning EntitySprocsb3.tt

OUTPUT
1) EntitySprocsb3.sql only 13 code lines:
“–
– This code was generated by a tool.
–
– Changes to this file may cause incorrect behavior and will be lost if
– the code is regenerated.
–
——————————————————————————–
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
– Creating stored procedures for c:\Development\Web\Proj\Proj.DA\ProjModel.edmx.
”

2) Exception:
Error 1 Running transformation: System.NullReferenceException: Object reference not set to an instance of an object.

Going to install VS 2010 RC. Give you feed back after.

Hi Ronald,

Thanks for the feedback about timestamp and SQL 2008. Did you happen to make the fix for it in the template? If so, I’d love to integrate the fix back into the download. If you contact me via the contact form, then I can repost it.

Just want to quickly comment that I tried running it against SQL Server 2008 and it works beautifully.
The issue that I found is, it generates param for timestamp, which will cause an error.
Also, the workflow seems a little bit convoluted, i.e:
1. create model
2. generate strored proc
3. update model with the new stored proc

Thanks

When you say, it only works with SQL Server 2005, do you mean the template won’t work with SQL Server 2008?

Could anyone provide some answer to my previous post?

Yes, thanks. Another question, i have a many-to-many relationship (customer, customer_address, address) and the generated sp for customer_address has originalCustomerID and originalAddressID fields. How do i map them in EF?

CHAR columns cannot be IDENTITY columns, so the template will not generate them for you. If the server is generating the CHAR column for you, though, the template should select that value so you can send it to EF. Does that help?

Noticed that “select SCOPE_IDENTITY() as [identityColumn]” were not generated for tables where my keys are char based. How should i create the inser sproc for this case?
