Hi!
I'm a noob to the EntityFramework and checking out features for our development to change the current database access with EntityFramework and Linq to Entities capabilities.
Now I'm confronting a last "KO" criteria:
I have the following situation:
- We are creating a plattform solution with a default database schema. For this I created a ssdl, csdl and msl file. Additionally I generated the Entities.cs class out of the csdl file. I can now access the data with EF and Linq to Entities - all is fine
- In case of a specific plattform implementation (customer specific solution) we sometimes need to extend the data in the following way:
* Guess we have a collection of classes in the plattform (described in csdl, msl and ssdl), e.g. the class PlattformA
* In the solution we need to extend the class PlattformA to have more fields => SolutionA extends PlattformA
* We use the table-per-hierarchy mechanism => the table PLATTFORM_A and the table SOLUTION_A are realized in the same table in the DB, only one field more for SOLUTION_A
Problem:
I have access to the ssdl, msl and csdl files of the plattform. I need additional entries in the csdl, ssdl and msl file for this inheritance but I don't want to extend the plattform files. Therefore I will create three new files, each of them will extend the plattform files.
Questions:
# How will I create a connection string for this set of 6 files?
# Is this possible? I read that it is possible to use more casdl files for one ssdl and vice versa. Therefore I guess a combination must be possible too.
For help in this I would be very grateful...
Cheers
Vic
