Reading default value from model for decision making

[rhariraman]

I saw the following issue has been fixed as part of EF core 9 version upgrade, hence thought of trying in my project.
#21006

After making the field as non-nullable and providing the default value, it worked while reading a particular document from the Azure Cosmos DB. However I was facing the issue while trying to read the specific attribute to make a decision.

For example,

I have a user model with the attributes like,

id
FirstName
LastName
...

I have decided to add a new attribute called

IsDeleted

I have kept this as non-nullable and provided the default as false in the model. This value isn't present for the existing documents.

With the EF core 9 upgrade, I am trying to read this user and I am able to see the user object is being populated with the value as false instead of null. But when I try to make a decision by checking the value of the attribute like below,

    user = user.IsDeleted == false ? user : null;

Here it fails with the following error. Could you help me how to resolve this?

That's just a compiler error. Review your code to make sure you only declared UserModel.IsDeleted once.
