I would suggest not using pluralization right now. Doing so makes any future code generation quite painful. I am feeling this pain now.

If you want to pluralize something, do it by convention. For example use “CompanyList” instead of “Companies”. The English language makes pluralization/singularization a bear.

I wish Microsoft made this easier for those who need to be able to determine singular and plural forms of a given type.

Maybe they do, and I just haven’t found it.

Tony,

I pulled documentation out of the T4 Toolbox build after discovering that Visual Studio 2010 uses a completely different help system. It was hard enough to build it for 2008 with Sandcastle, I simply didn’t have time to deal with two help systems.

In the article you mentioned the “T4 Toolbox documentation”

Where can i get this so i can add it to my VS2008 documentation?

Thanks

The project item template in T4 Toolbox assumes you have SQL Server 2005 or 2008 Express Edition installed. Standard, Enterprise or Developer editions of SQL Server don’t support the ability to attach databases in the connection string.

When I try to add an Entity Framework DB to my sln, it says “Connection to SQL Server files require SQL Server Express 2005″ and won’t let me proceed. But I have SQL Server 2008 Pro! Argh!

Hello Oleg, i tried to create the source code using your sample download and got struck due to an issue on the default constructor MyTest.vb

Public Sub New()
MyBase.New(”name = MyTestEntities”, “MyTestEntities”)
MyBase.ContextOptions.LazyLoadingEnabled = true
OnContextCreated()
End Sub

I am getting an error like this
“Format of the initialization string does not conform to specification starting at index 123.”

The .VB file cannot able to access the configuration file.Can you advice what went wrong ?

Regards
Dhinesh Kumar

Jeff, I think two things are still missing in EF 4.0 that we have in LINQ to SQL - automated import of stored procedures and support for enums in entity classes and LINQ. In my mind, these two limitations make L2S superior to EF from the standpoint of implementing a cost effective data access layer in .NET 4.0

Great stuff Oleg. So - is it fair to say, from a Data Driven Design point of view, we have the maintenance simplicity we enjoyed with LINQ to SQL while using a Microsoft supported framework?

I’m hoping that approaches like this, along with the improvements in EF in .Net 4.0, will facilitate reasonable use of EF in medium and large scale projects.
