You are using an older version of SolrNet. This error is a known issue with older versions of SolrNet and Solr 4.X. Please grab an updated version from one of the following:

- [NuGet - Pre-Release v0.4.0-beta2][1]
- [Solr Nightly Builds][2] - (click the Artifacts link to get access to the downloadable zip)
- [GitHub Source][3] - pull the latest source down and compile locally or use a [release][4].

Please note, in addition to Paige Cook's answer, that currently (Jan 2015) NuGet doesn't hold the latest version. Using `Install-Package SolrNet -Pre` you get an assembly with version number `0.4.0.2002`, which is the current number, but there is a more recent version within this version number (tricky!). To fix the problem, use [GitHub][1] or [SolrNightlyBuilds][2] instead.
