Ive been getting an error, I have an error with the entity framework. I have a SQL Server 2005 SP2.

When the ProviderManifestToken = “2008” I get this error. 

The version of SQL Server in use does not support datatype 'datetime2'.

Ive done the change shown here and when chagned to “2005” I get 

Schema specified is not valid. Errors: 
DatabaseAccess.Schema.Model1.ssdl(2,123) : error 0169: All SSDL artifacts must
target the same provider. The ProviderManifestToken '2008' is different 
from '2005' that was encountered earlier.

I dont understand

My Database version is Microsoft SQL Server Standard Edition (64-bit) 9.00.3042.00

Ive tried deleting the schema and re adding it to no avail. Restarting etc

Ive alse made all my date time fields nullable

    I have seen this before and it is to do with the datetime being Nullable. I think if you break into the code you will see that the value of the date time when you create a new instance of the class is a default(DateTime) and not null and it is this value that is causing the error.

    If possible, can you try nulling the DateTime value before saving changes on the context?

    I will try to put together a sample demonstrating when and how this occurs.

    Found a brief explanation here:
