EF creates labels that can't be broken

Application Scenarios:

When developing with EF's datebase fitst pattern, entities have T4 files that are generated from the database and are regenerated every time they are saved, and if we add validation tags to the entity classes that have T4 generated, then the save is lost.

Solution:

　　

1[Metadatatype (typeof(Openguilogvalidate))]//let Openguilog share openguilogvalidate metadata information2      Public Partial classOpenguilog3     {4     }5 6      Public classopenguilogvalidate7     {8[Stringlength (5, errormessage ="")]9 [Required]Ten          Public stringName {Get;Set; } One  A}
