            <title>[CSHARP-677] Driver causes application crash after a random amount of time</title>
                <link>https://jira.mongodb.org/browse/CSHARP-677</link>
                <project id="10041" key="CSHARP">C# Driver</project>
                    <description>&lt;p&gt;The application works fine for a long period of time then suddenly throws an exception (attached), and the app eventually crashes.&lt;/p&gt;

&lt;p&gt;Before crash the exception shows that a document in database has a field (auto property in C#) of an incorrect type. For example recently it was a &lt;br/&gt;
DateTime FirstEventTime &lt;/p&gt;
{get;set;}
&lt;p&gt; with a value of 0. And the exception was &quot;Cannon cast from double to DateTime&quot;. That is, the database becomes inconsistent (no query can be performed on that collection from C#) until an update of that property or a manual document removal. &lt;/p&gt;

&lt;p&gt;The application is multithreaded, without any JavaScript for any DB operation, only the Insert(), Update(). FindOneById() and AsQueryable() methods provided by MongoCollection&amp;lt;T&amp;gt;.&lt;/p&gt;

&lt;p&gt;Attached are a couple of stacktraces (Payment.Nr is a string autoproperty).&lt;/p&gt;</description>

&lt;p&gt;This is apparently caused by a bug in Mono which is fixed in the 3.0 version of the Mono runtime.&lt;/p&gt;</comment>
