Is it necessary to use tomcat for configuring Solr with asp.net. by this link [link]https://www.codeproject.com/Tips/480091/Using-Solr-for-Search-with-NET-Csharp i configured and it works!! but it uses solr 1.4 version and i want to update my solr version. And [link]https://cwiki.apache.org/confluence/display/solr/Running+Solr+on+Tomcat it says that you cannot configure the tomcat with version 5 or latest from it. so how to configure asp.net with solr latest version ?
Latest Solr runs as standalone black box. Do not look at ancient tutorials for Tomcat information, they are not useful anymore. And it is a separate issue from connecting to it via .NET client.
For the client part, the source-code version of SolrNet is more up to date. And it should work with latest Solr, with the main issue being that the URL for Solr now must include collection name, so http://localhost:8983/solr/collectionname . Check for parameters to set core or collection or similar.
There is also Solr Express you may want to have a look at.
