I am trying to load the old version of farpoint dll in my project by using below code

```
     System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFile(@"FarPoint.Web.Spread.dll");
    System.Type MyDLLFormType = assembly.GetType("FarPoint.Web.Spread.FpSpread");
    var c = Activator.CreateInstance(MyDLLFormType);

```

The problem is after the instance is created, all the available methods of farpoint are not available 
[ for example - if i create the object directly the methods like saveExcel or savechanges are available with the instance]

```
                FpSpread fpProxyObject = new FpSpread();
                fpProxyObject.SaveExcel();

```
