{
}
public partial class UserRole : IdentityUserRole<Guid>
{
}
public partial class UserClaim : IdentityUserClaim<Guid>
{
}
public partial class Role : IdentityRole<Guid>
{
public Role() : base()
{
}
public Role(string roleName)
{
Name = roleName;
}
}
public partial class RoleClaim : IdentityRoleClaim<Guid>
{
}
public partial class UserToken : IdentityUserToken<Guid>
{
}
