Is there a cheat sheet for the .NET library System.ComponentModel.DataAnnotations?
This is the library that is used for marking up ASP.NET MVC 3 Model classes.
For example:
[Required]
[MaxLength(20)]
[Display(Name = "Asset")]
public string AssetNumber { get; set; }
[Required]
public int StatusID { get; set; }
How about the MSDN documentation
