How do you pass a PartitionKey to Execute a StoredProcedure?
<p>I'm trying to execute a stored procedure on a partitioned collection (server side partitioning) from the .net SDK (v1.6.3). </p>

<p><code>await client.ExecuteStoredProcedureAsync&lt;string&gt;(UriFactory.CreateStoredProcedureUri("db0", "collection0", "testsproc0"), storedProcedureParams);</code></p>

<p>I receive the error "PartitionKey value must be supplied for this operation". In fact, I see this error in the Azure Portal when I play around with the Script Explorer. However, I see no way to add a PartitionKey. Is this a limitation with the API and partitioned collections right now, or am I missing something? </p>
