Entity Framework code-first - adding a column that already exists in the database

Question

I am using .NET Core 3.1.2 and Entity Framework Core 3.1.2.

Approach is code first, but I have one column in my SQL Server table that already exists (Country), and I don't have it in the entity class.

So I have added a plain string property

public string Country { get; set; }

Now, when I try to save this table (e.g. customer) I get an error:

Invalid column name Customer_Country

I cannot create migration because the column already exists; is there a solution for this?
