Add the [NotMapped] attribute to the property.

>If I add a property to an entity and run 'Generate database from Model' I get a warning that the existing store schema will be overwritten and the generated SQL contains something like this:

-- --------------------------------------------------
>-- Dropping existing tables
>-- --------------------------------------------------
>
>IF OBJECT_ID(N'[dbo].[Customers]', 'U') IS NOT NULL
>    DROP TABLE [dbo].[Customers];
>GO
>-- --------------------------------------------------
>-- Creating all tables
>-- --------------------------------------------------
>
>-- Creating table 'Customers'
>CREATE TABLE [dbo].[Customers] (
>    [Id] int IDENTITY(1,1) NOT NULL,
>    [Name] nvarchar(max)  NOT NULL,
>    [FristName] nvarchar(max)  NOT NULL
>);
>GO

How do you get the generator to change that behaviour ?
