Previously, I had a website that was leveraging a third party dll that wrapped
http api calls to their service. This worked in an earlier version of mono,
and now I am getting null reference exceptions when trying to access these
services. The trace below seems to indicate the error - a call to KillBuffer
is occuring, and then the Close method is called. KillBuffer sets writeBuffer
to null, and at the end of the Close method (around line 658), there is a check
as such:
if (length != -1 &amp;&amp; length &gt; writeBuffer.Length)
In this case, writeBuffer would be null, and believe this is the offending
line. Here is the trace:
