database - EntityFramework5 Code-First Migration -

i running entityframework5 code-first , enabled migration package manager console. after enabled migration configuration.cs file added migrations folder, not initialcreate.cs.

i change class from

public class product {     public product()     {         this.creationdate = datetime.now;     }      [key, databasegenerated(databasegeneratedoption.identity)]     public guid productid { get; set; }      public datetime creationdate { get; set; }      public string image { get; set; }      public string imagethubmnail { get; set; }      [foreignkey("category")]     public guid categoryid { get; set; }     public virtual category category { get; set; }      [foreignkey("company")]     public guid companyid { get; set; }      public virtual company company { get; set; } } 

to

 public class product {     public product()     {         this.creationdate = datetime.now;     }      [key, databasegenerated(databasegeneratedoption.identity)]     public guid productid { get; set; }      public datetime creationdate { get; set; }      public string name { get; set; }      public string image { get; set; }      public string imagethubmnail { get; set; }      [foreignkey("category")]     public guid categoryid { get; set; }     public virtual category category { get; set; }      [foreignkey("company")]     public guid companyid { get; set; }     public virtual company company { get; set; } } 

how can fix it?

note:

1.i new in migration database.

2.business objects files , dbcontext class different class libraries.

add initial migration manually using add-migration "initial" in package manager console. if still doesn't create migration file, manually delete database , migrations folder , enable-migrations followed add-migration "initial" should work.
