Migrations de machine wireup.

Question

J'ai essayé de câbler un de mes projets pour utiliser Machine.Migrations pour les migrations de base de données. Cependant, je n'ai pas été capable de faire cela. J'ai eu des erreurs bizarres. J'ai essayé d'utiliser la tâche MSBuild mais j'obtiens l'erreur suivante.

Target MigrationMachine: 
    D:\repositories\core\playground\minhajuddin\MachineMigrationsTest\lib\Machine.Migrations.targets(20,5): error MSB4062: The "Machine.Migrations.MigratorTask" task could not be loaded from the assembly D:\repositories\core\playground\minhajuddin\MachineMigrationsTest\lib\Machine.Migrations.dll. Could not load file or assembly 'file:///D:\repositories\core\playground\minhajuddin\MachineMigrationsTest\lib\Machine.Migrations.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, and that the assembly and all its dependencies are available. 
Done building target "MigrationMachine" in project "MachineMigrationsTest.csproj" -- FAILED. 

Lorsque j'essaie d'utiliser migrate.exe. Je reçois l'erreur suivante:

code dans 001_create_emp_table.cs

namespace MachineMigrationsTest { 
    public class CreateEmpTable : SimpleMigration { 
     public override void Up() { 
      Schema.AddTable("Emp", 
       new Column[] 
        { 
         new Column("Id",ColumnType.Long,0,true,false) 
        }); 
     } 

     public override void Down() { 
      Schema.DropTable("Emp"); 
     } 
    } 


} 

S'il vous plaît aidez-moi.

Merci, Khaja Minhajuddin.

Essayez de nommer votre classe le même que votre fichier, sauf pour la version: create_emp_table

Edit: Aussi, essayez de supprimer l'espace de noms. Je pense que les MMigrations peuvent exiger que les choses ne soient pas dans un espace de noms.
