Does any namespace changes EF to 4.1 from 4.0, could not find AttributeConfigurationConvention<T1, T2, T3>

I implemented AttributeConfigurationConvention for decimal 开发者_JAVA百科precision attribute for EF 4.0. It was worked well for our apps but install 4.1 I got compile time Error ;

'System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.DecimalPropertyConfiguration' is inaccessible due to its protection level

Does any namespace change or EF 4.1 doesn't need this implementation?

Thanks in advance.

I don't think that EF 4.0 had this class at all. Perhaps you mean EF CTP5? Anyway, for EF 4.1 DecimalPropertyConfiguration is in namespace

System.Data.Entity.ModelConfiguration.Configuration

It's possible that the namespace changed indeed from CTP5 to EF 4.1.

question could be close... I found Rowan Miller (MSFT) comments on microsoft social forums, he said that; "EF 4.1 does not include support for custom conventions. CTP5 included an early preview of conventions but the feature was not ready to be included in the supported go-live releases. ~Rowan"
