Set decimal(16, 3) for a column in Code First Approach in EF4.3 [duplicate]

Answer 1

You can also set the precision of decimals using the code-first model mapping approach like this:

public class MyEntityMapping : EntityTypeConfiguration
{
    public MyEntityMapping()
    {
        HasKey(x => x.Id);
        Property(x => x.Id).IsRequired();
        // .HasPrecision(precision, scale)
        // 'precision' = total number of digits stored,
        // regardless of where the decimal point falls 
        // 'scale' = number of decimal places stored
        Property(x => x.DecimalItem).IsRequired().HasPrecision(16, 6);
    }
}
