Hello everyone,

I am using ASP MVC with Entity Framework.

I have created a table "Voiture" which has "Modele","Marque","Construction Date" and "Price" as attributs. When I am trying now to add a new attribut "Color" to this Table, I get always an exception :

<pre>Invalid column name 'Color'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Invalid column name 'Color'. 

And when I take a look at my Table in the Server Explorer, I don't find the attribut Color although I wrote it in my Model class.

What I have tried:

I try to enable the migration using PM .
