    text
    copied!<p>Cannot access a disposed object. Object name: 'System.Net.Sockets.TcpClient'.</p> <p>I don't understand why it happen and how to deal with it. I use Ninject, my application is based on mvcstarter.codeplex.com/ what I do is delete some user or pages from my database and it happen for no reason(that I can find).</p> <p>Any help would be appreciated!</p> <p>Thanks a lot!</p> <p>*Edited Also, after a while it get back to normal and I can fetch my data from Mongo... My unit tests work fine...</p> <p>Here's my code for my session :</p> <pre><code>public class MongoSession : ISession{ private readonly Mongo _server; public MongoSession() { //this looks for a connection string in your Web.config - you can override this if you want _server = Mongo.Create("MongoDB"); } public T Single&lt;T&gt;(System.Linq.Expressions.Expression&lt;Func&lt;T, bool&gt;&gt; expression) where T : class { return _server.GetCollection&lt;T&gt;().AsQueryable().Where(expression).SingleOrDefault(); } public IQueryable&lt;T&gt; All&lt;T&gt;() where T : class { return _server.GetCollection&lt;T&gt;().AsQueryable(); } /*public void Add&lt;T&gt;(T item) where T : class { _provider.DB.GetCollection&lt;T&gt;().Insert(item); }*/ public void Save&lt;T&gt;(IEnumerable&lt;T&gt; items) where T : class { foreach (T item in items) { Save(item); } } public void Save&lt;T&gt;(T item) where T : class { var errors = DataAnnotationsValidationRunner.GetErrors(item); if (errors.Count() &gt; 0) { throw new RulesException(errors); } _server.Database.GetCollection&lt;T&gt;().Save(item); } //this is just some sugar if you need it. /*public T MapReduce&lt;T&gt;(string map, string reduce) { T result = default(T); using (MapReduce mr = _provider.Server.CreateMapReduce()) { MapReduceResponse response = mr.Execute(new MapReduceOptions(typeof(T).Name) { Map = map, Reduce = reduce }); MongoCollection&lt;MapReduceResult&lt;T&gt;&gt; coll = response.GetCollection&lt;MapReduceResult&lt;T&gt;&gt;(); MapReduceResult&lt;T&gt; r = coll.Find().FirstOrDefault(); result = r.Value; } return result; }*/ public void Delete&lt;T&gt;(System.Linq.Expressions.Expression&lt;Func&lt;T, bool&gt;&gt; expression) where T : class { var items = All&lt;T&gt;().Where(expression); foreach (T item in items) { Delete(item); } } public void Delete&lt;T&gt;(T item) where T : class { _server.GetCollection&lt;T&gt;().Delete(item); } public void Drop&lt;T&gt;() where T : class { _server.Database.DropCollection(typeof(T).Name); } /*public void CommitChanges() { //mongo isn't transactional in this way... it's all firehosed }*/ public void Dispose() { _server.Dispose(); } } </code></pre> <p>And the calling code would be something like this, my _session is pass to my Controller in the contrutor using Ninject, with the binding in my global.cs :</p> <pre><code>Bind&lt;ISession&gt;().To&lt;MongoSession&gt;().InSingletonScope(); public virtual ActionResult Liens() { var shortcutLionks = _session.All&lt;ShortcutLinks&gt;().ToList(); ViewData.Model = shortcutLionks.Count &gt; 0 ?
