title: mvc 4 MultiSelect list & EF many to many
body: <p>I have these entities (there is many to many connection between them): </p>
  
  <pre><code>public class Post
  {     
      public Guid PostId { get; set; }     
      public string Name { get; set; }       
      public virtual ICollection&lt;Tag&gt; Tags { get; set; }
  }
  
    public class Tag
  {
      public int TagId { get; set; }
      public string Name { get; set; }
      public virtual ICollection&lt;Post&gt; Posts { get; set; }
  }
  </code></pre>
  
  <p>I'd like user,  when he creates Post, to choose data from MultiSelectList and MultiSelectList to pass that data to Post.Tags. How can I do that ?</p>
