I try to get into Microsoft Azure. For that i just set up the demo application described under

<https://azure.microsoft.com/de-de/documentation/articles/iot-hub-csharp-csharp-getstarted/>

now i want to try out stream analytics, for that i configured an input, listening to the IoT Hub and an Output writing to a DB.

Whenever i start the Stream Analytics Job i got an error like that:

```
Stream Analytics job has validation errors: Unable to load type Microsoft.Streaming.StreamingExceptions.Exceptions.Job.ObjectModelValidationException required for deserialization.

```

Why is that? What did i miss here?
