In past projects with versions of EF5 and EF4, the IsRequired() fluent API method would thrown a DbEntityValidationException if the property was null or an empty string.

Entity: public class Application : BaseEntity { public string Name { get; set; } // navigation properties public IList<Role> Roles { get; set; } } Configuration: internal class ApplicationMapping : EntityTypeConfiguration<Application> { public ApplicationMapping() { // table name this.ToTable("Applications"); //

public class Foo { public int Id { get; set; } public int UserId { get; set; } } This appears to be the way to do this asynchronously: DatabaseContext db = new DatabaseContext(); Foo foo = await db.Foos.FindAsync(fooid); How does one asynchronously get all of the Foos for a specific user based on UserId's value?

[ Node name (if any) = Extent1,Column name = HasErrors ]"} ) I double checked the mapping
