Occurs when updating the data model.
when updating the model at the WPF with an EF Entity Framework connection to a SQL Server database,
then it may be that the connection is taken over incorrectly as a data context.

Solution:
You have to correct the context by name in the * .Context.cs file of the application
In this case:
public partial class dbContext : DbContext { public dbContext() : base("name=dbContext") { }
|
On:
public partial class dbAppData_Context : DbContext { public dbAppData_Context() : base("name=dbContext") { }
|
After the change
The problem can occur when updating the data model from within the designer
