Microsoft released the final version of Entity Framework (EF) 4.2. Although this update only contains one error correction, it is interesting that it applies Microsoft's semantic version control and they try to put EF and.. NET Framework, but they said the process was not as smooth as they expected.
This error fix is related to an issue in EF 4.1 update 1. According to the blog of the ADO. Net group, "Use third-party generic EF to provideProgramDevelopers who implement the provider factory will be affected, such as wrappingproviderfactory. "Although this is the only update in EF 4.2, Microsoft still sticks to their semantic Version Control Plan:
Obviously, a single error correction is generally insufficient to form a minor version, but we want to take this opportunity to apply semantic version control instead of calling this version "Ef 4.1 Update 2 ".
Microsoft has separated EF and. NET Framework from version 4.0. EF 4.1 adds the dbcontext API andCodeSupport for advanced functions. These features can be updated independently in future EF versions, while other features depend on the main components of. NET Framework. These features include enumeration support, spatial data types, automatically compiled LINQ queries, Table value functions, and multi-result stored procedures. According to Microsoft, these features will be updated in. NET Framework 4.5.
The blog of the ADO. Net group says they still intend to provide EF independently of the. NET Framework, but this process may take longer than expected:
When we say that we still want to take those classes out of the Framework in the future, we mean that we want the entire EF to be independent, but we still have some technical problems not solved, these problems have not been investigated in depth, so we do not think they will result in the short term.
EF 4.2 can be downloaded from nuget.
