Finnaly, i found! The problem is i missed to add some dll's to my project on Mono. The clear way to do that, copy the project that runs in your local Windows to Ubuntu Server.Open a new project in Mono , copy the code and add all the references. Remember that use framework 4.5 and add references of 4.5 version.
References you should have to add:
- System.Web.Cors
- Microsoft.AspNet.Signalr.Core
- Microsoft.Owin
- Microsoft.Owin.Cors
- Microsoft.Owin.Diagnostics
- Microsoft.Owin.Host.HttpListener
- Microsoft.Owin.Hosting
- Microsoft.Owin.Security
- Newtonsfot.Json
- Owin.dll
- Microsoft.Csharp
- System.Core
- System.Data
- System.Data.SetExtensions
- System.Xml
- System.Xml.Linq
