Please update the examples for .NET SDK

### Describe your suggestion

I installed the required package, and seemed API changes a lot compared with the version used in .NET samples. Could you update samples with current API version? And could you also add samples for command job query and cancel? Thanks!

### Additional details

_No response_

Start by locating the existing .NET SDK samples and checking which API version they use against the current Azure Machine Learning SDK. Review the existing job examples first; done means the samples use the current API and include command job query and cancellation examples.
