Answer 1

The most basic analysis is !analyze -v, which already helps in your case. Make sure your symbols are correct first. So the following 3 commands are enough to find out the exception:

0:000> .symfix
0:000> .reload
0:000> !analyze -v
[...]
CLR_EXCEPTION
    Tid    [0x0]
    Frame  [0x00]

    String [System.ArgumentNullException]
    Failure Bucketing
    Data Bucketing

BUGCHECK_STR:  CLR_EXCEPTION_System.ArgumentNullException    
DEFAULT_BUCKET_ID:  CLR_EXCEPTION_System.ArgumentNullException
[...]

For .NET, there's also an extension called sos which can help:

0:000> .loadby sos clr
0:000> !pe
Exception object: 00000000045ff3b8
Exception type:   System.ArgumentNullException
Message:          Value cannot be null.
InnerException:   <none>

You probably also need the call stack:

0:000> !clrstack
The version of SOS does not match the version of CLR you are debugging.  Please
