copied!<p><strong><em>UPDATE</strong> This answer has been updated for SignalR version 1.0</em></p> <p>This is how to build a SignalR <code>IDependencyResolver</code> for Simple Injector:</p> <pre class="lang-cs prettyprint-override"><code>public sealed class SimpleInjectorResolver : Microsoft.AspNet.SignalR.IDependencyResolver { private Container container; private IServiceProvider provider; private DefaultDependencyResolver defaultResolver; public SimpleInjectorResolver(Container container) { this.container = container; this.provider = container; this.defaultResolver = new DefaultDependencyResolver(); } [DebuggerStepThrough] public object GetService(Type serviceType) { // Force the creation of hub implementation to go // through Simple Injector without failing silently. if (!serviceType.IsAbstract && typeof(IHub).IsAssignableFrom(serviceType)) { return this.container.GetInstance(serviceType); } return this.provider.GetService(serviceType) ?? this.defaultResolver.GetService(serviceType); } [DebuggerStepThrough] public IEnumerable<object> GetServices(Type serviceType) { return this.container.GetAllInstances(serviceType); } public void Register(Type serviceType, IEnumerable<Func<object>> activators) { throw new NotSupportedException(); } public void Register(Type serviceType, Func<object> activator) { throw new NotSupportedException(); } public void Dispose() { this.defaultResolver.Dispose(); } } </code></pre> <p>Unfortunately, there is an issue with the design of the <code>DefaultDependencyResolver</code>. That's why the implementation above does not inherit from it, but wraps it. I created an issue about this on the SignalR site. You can read about it <a href="https://github.com/SignalR/SignalR/issues/400" rel="nofollow">here</a>. Although the designer agreed with me, unfortunately the issue hasn't been fixed in version 1.0.</p> <p>I hope this helps.</p>
