Hi Alexander,
The walk-throughs provide sample applications of various methods for querying
the Virtuoso RDF & SQL stores in .Net using both the ADO.Net Provider and HTTP.
The Entity Framework samples require a SQL/relational mapping and creating a
SQL View of the RDF SPARQL query seems the obvious way of doing this.
Have you looked at the dotnetRDF project which provides an RDF library for .Net
and supports Virtuoso as detailed at:
http://www.dotnetrdf.org/content.asp?pageID=Using%20Virtuoso%20Universal%20Server
This may be more what you are looking for ...
Best Regards
Hugh Williams
