Entity Framework contains T4 templates that can generate C# classes for database entities. However, these T4 templates don’t generate separated interfaces for the generated classes. This makes it difficult (if not impossible) to apply IoC and unit testing
Entity Interface Generator
This project contains customized T4 templates which can generate interfaces and attributes for the DbContext class and entity classes.
What are the benefits?
- Enable IoC and
Unit Tests by generating separated interfaces for entities.
The interfaces could be generated in a separated and independent assembly to be redistributed without the need of the actual data access assembly. This cannot be done with EF 6.0 because of 2 exceptions which have been addressed in version
18.104.22.168 and 22.214.171.124.
If you must have separated assemblies, please download versions prior to 126.96.36.199 and use EF 5.0. The breaking changes are introduced only in EF 6.0.
- Generic unit test to smoke test the generated model by getting top 1 of every table.
