Replacing "try catch (Response)" with "as Response"

It all started when I got first chance exception and I have catching all exception enabled so I decided to replace:
```csharp
private static Response CastResultToResponse(dynamic result)
{
    try
    {
        return (Response)result;
    }
    catch
    {
        return null;
    }
}
```
with
```csharp
private static Response CastResultToResponse(dynamic result)
{
    return result as Response;
}
```
But then I got caught in element of optimizing... Removing methods and stuff...
