Jeff Rodenburg created a C# API for interoperation with Solr. The API supports:
Adding, updating and deleting documents from a solr index.
Configuration support for multiple solr instances.
Flags for Read/Write modes in support of solr replication.
Search queries that return strongly-typed objects
Support for facets
Update December 30 2007: SolrSharp has a new home @
http://www.codeplex.com/solrsharp. The source code is available through the codeplex repository, as well as a zipped distribution. Please use the discussion forum and other services at
http://www.codeplex.com/solrsharp.
Many thanks to the Solr community for initially giving us a home here on the Solr wiki and to Ryan for hosting the source code under subversion.
