   Do you have any details on the exceptions?
   Maybe attach a fiddler session to see what the API response is?

   I get this:

   The remote server returned an error: (401) Unauthorized.

   You can reproduce the error by using the WindowsForms sample changing the target framework to .NET 4.5

   From the dropbox's documentation (https://www.dropbox.com/developers/core/docs):
   401 Bad or expired token. This can happen if the user or Dropbox revoked or expired an access token. To fix, you should re-authenticate the user.

   Sounds like you haven't authenticated. Do the other API calls work like GetMetadata?

   Is your API key full dropbox or app folder permissions? If its app folder are you seeing the sandbox flag?

   Please try this, using a .NET 4.5 project

       private void brwLogin_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
       {
           if (e.Url.Host.Contains("google"))
           {
               //Callback url reached, user has completed authorization
   
              //Access the App folder
               _client.UseSandbox = true;
   
               //Now convert the request token into an access token
               _client.GetAccessTokenAsync((userLogin) =>
                   {
                       //Save the Token and Secret we get here to save future logins
                       _userLogin = userLogin;
   
                       GetContents();
                   },
                   (error) =>
                   {
                       //Some sort of error
                       MessageBox.Show(error.Message);
                   });
           }
       }
   
       private void GetContents()
       {
           _client.GetMetaDataAsync("/", (response) =>
           {
               byte[] data = _client.GetFile("note.txt");
               File.WriteAllBytes(@"C:\note.txt", data);
               data = null;
           },
           (error) =>
           {
               Console.WriteLine(error.Message);
           });
   
       }
   

   It works on .NET 4.0, but it doesn't work on .NET 4.5

   Thank you
