DB context code gen item generates incorrect code

Hi :) I'm working with entity

I've asked VS to generate a DB context code gen item but get errors:

is there somewhere I need to go to to get upto date templates?

protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }

Error 1 The type or namespace name 'DbModelBuilder' could not be found (are you missing a using directive or an assembly reference?)

any ideas?

Re: DB context code gen item generates incorrect code

Which version of EF are you using.

Re: DB context code gen item generates incorrect code

I have this on my pc:

C:\Program Files (x86)\Microsoft ADO.NET Entity Framework 4.1 RC

protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }

First I think you should remove "throw new UnintentionalCodeFirstException();" this statement because when it's executed to this statementerror will be thrown out

And then

The type or namespace name 'DbModelBuilder' could not be found (are you missing a using directive or an assembly reference?)

Please make sure that you've imported the EF dll and refer the namespaceIn fact I strongly you using NuGetthis is a very nice tool that helps you to get EF dll and refer it easily and automatically

Now you can see this and follow the stepshttp://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx

Re: DB context code gen item generates incorrect code

cheers decker :)

I installed ef 4.1 using new the package manager before, and I see in the references folder

system.data.entity

And I have the errors still.

why should I delete that code that throws the error since it was generated by entity?

Your throw new Exceptionis fully automatically generated by EFSorry if soplz keep itPSI don't remember I have ever seen it beforeHaha

QuantumInformation
system.data.entity

This is the namespaceand is there an EntityFramework.dll there

Re: DB context code gen item generates incorrect code

yes,

Assembly System.Data.Entity
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Data.Entity.dll
