Logic bug of An ADO. NET Entity Framework

Contact me these daysADO. NET Entity Framework suddenly found a strange bug.

First, let's look at this directory structure:

I saved the EDM model to a directory named "A", edited the model, and set its namespace to "commondbmodel ":

Open commondbmodel. Designer. CS to view the generatedCode:

 

The above namespace is actually "A", not the "commondbmodel" I set ".

This namespace is apparently consistent with the directory name, so I modified the directory name "commondbmodel ":

Modify and save the model in symbolic form to refresh the generated code and view the generated code:

 

It turns into "commondbmodel ".

That is to say, the namespace previously set in the property panel is invalid at all. It uses the directory name as the namespace name. I think this is not logical.

If you directly put the model under the app_code directory, the namespace attribute will take effect normally.
