如何解决类的名称不能自动单数化

Question

Using EF to create the classes I choose the singularize option. Some of the classes were singularize but other doesn't.

This work ok:

products -> product
presentations -> presentation

But this two wasn't:

price_sources -x-> price_source
user_types -x-> user_type

• How can I fix the names of the classes weren't singularized?
• How can I fix the names of the classes with underscore?
• How make sure next update from db does not break the names again?

Answer 1

Manual method:

Right click on empty space in the edmx window and select Model Browser .

In the Model Browser of the edmx file you can rename the generated class names for the Tables under the DBModel --> Entity Types by right clicking on the class names and selecting Rename . This will not break the code on subsequent updating of the models from database. But if you delete and re-add the same table you will have to repeat the above steps.

I do these steps to avoid the CA warning for using underscores in class / property names

Answer 2

The answer is that tables with underscores cannot be automatically pluaralized/singularized in EM.

For more details, see: https://blogs.msdn.microsoft.com/efdesign/2008/12/01/pluralization/

You will have to configure the table name explicitly.

You can also use a custom pluralization service to write your own rules.
