How do I fix exceptions from HRESULT 0x800AC472?
The only way around that is going to be to make your object model call from a loop. You will need to continue to retry the call until it succeeds–so you’ll set a success bit right after the call and then have an exception handler that catches (and eats) the 0x800AC472 exception which allows the loopback to continue.

How do you handle a sequence that has no elements?

How do you avoid Argumentnullexception?
To prevent the error, instantiate the object. An object returned from a method call is then passed as an argument to a second method, but the value of the original returned object is null . To prevent the error, check for a return value that is null and call the second method only if the return value is not null .

What is an HRESULT error?
What is exception from Hresult?
Each exception is mapped to a distinct HRESULT. When managed code throws an exception, the runtime passes the HRESULT to the COM client. When unmanaged code returns an error, the HRESULT is converted to an exception, which is then thrown by the runtime. For information about HRESULT values and their corresponding .
