I'm not sure if this is actually a bug or whether Virtuoso is producing invalid SPARQL JSON, the <a href="http://www.w3.org/TR/sparql11-results-json/">specification</a> shows all the data encoding RDF terms as being enclosed in JSON strings.</p>
<p>
However the specification does not say anything explicit about whether using native JSON terms like dates, integers, booleans etc is acceptable. I will investigate further and get back to you on this</p></td>

Hi Rob,</p>
<p>
Indeed maybe Virtuoso does not conform to the specification. I have tested dotNetRDF with 4store as well, and, when doing so, I didn't encounter this issue. So I wasn't sure whether I should report a bug or a suggested improvement. All I have noticed is that the query works without any problems if this little json token peculiarity of Virtuoso is "excused" :)</p>
<p>
Best regards,</p>
<p>
Dimitri</p></td>

I'm not so sure this is a Virtuoso problem on further investigation, it may actually be a Json.Net perculiarity instead</p>
<p>
Raw dates are not allowed in JSON and would be encoded in strings (thus meeting the SPARQL JSON spec) so it looks like it may be the case that Json.Net is simply being smart and identifying certain strings as belonging to certain types. I will write up a few test cases to confirm this and then put in place appropriate fixes.</p></td>

Many thanks! In any case my little hack has solved my problem for now. But I hope that the info helps and, also, it will be cooler when we can just use the library directly from Nuget :)</p></td>

Per my previous comment this was a Json.Net perculiarity with it auto-identifying the valid string wrapped date as a special token type causing issues for the parser. This has been fixed in default</p>
<p>
</p>
<p>
For future reference code is in Mercurial and available at BitBucket - http://bitbucket.org/dotnetrdf/dotnetrdf so you can always fork and send us a pull request if you have a patch for an issue. </p></td>
