Hi i have upgraded my project from tridion 2011 sp1 dd4t 1.24 to tridion 2013sp1 dd4t 1.3. after upgrade my code is working fine with static pages and reed component presentation but it throws null when try to read dynamic component using below code

  public ViewResult Component(int publicationId, int componentId, string viewName)
        {
            TcmUri tcmUri = new TcmUri(publicationId, componentId, 16, 0);
            IComponent component;
            //IComponent c = ComponentFactory.GetComponent("tcm:71-23455-16", "tcm:71-23868-32");
            if (ComponentFactory.TryGetComponent(tcmUri.ToString(), out component))
            {
                return View(viewName, component);
            }
            // optionally throw exception in case component is not found
            return null;
        }

i have checked CT and component is published successfully in broker.

i have also tried getCompontnt mehtod 

IComponent c = ComponentFactory.GetComponent(tcmUri.ToString(), tcmUrict.ToString());

but gives error 

[ComponentNotFoundException: Error in the application.]

OR when i select CT output format - HTML Fragment it gives below mentioned error

Line 51:             if (ComponentFactory.TryGetComponent(tcmUri.ToString(), out component))

Line 52: { Line 53: return View(viewName, component);

You get an XmlException because the content of your DCP cannot be parsed as XML. Most likely this means your DCP is not a DD4T XML model.

I suggest to start with the database and look at the content of that DCP. I believe your CT is not a DD4T CT and such not producing the right XML for a DD4T model.
