what is the reason to this error and how can I fix this ?

Answer 1

I had some similar issue like this.

Try looking inside the packages.config and you should see the Lucene package and the version that is looking for when you compile. Try removing tha package from the Nuget Package Manager, and then, enter the packages.config and check if it's still pointing to some version. If it is the case, remove the reference inside this file, and then install again the version you want to use.

Then come here again and check if it's pointing the right version. I think that you can even change here the version in order to point to the right place.

I hope this helps

Thanks your answer is helpful, and I have fix my issue in following way, I removed all Lucene.Net from my solution and I have downloaded lucene.net from https://nhcontrib.svn.sourceforge.net/svnroot/nhcontrib/trunk/src/NHibernate.Search and added reference manually, Now it is working
