Hi Sreekanth, Lucene.Net 3.0.3 is likely not going to work well with .NET 8+, and is untested/unsupported. It only targets .NET Framework 3.5 and 4.0 (which should be compatible with .NET Framework up through 4.8.1 just fine). For use with modern .NET, we recommend using our latest 4.8.0 beta, currently 4.8.0-beta00017. The jump in major/minor version represents the upstream Lucene version we're trying to match.
You might possibly have some limited success using 3.0.3 on modern .NET 8+ on Windows, but I know that in particular you will have problems on Linux (i.e. in containers) or on macOS. I was able to get a minimal example working with 3.0.3 using RAMDirectory on macOS with .NET 10 RC2, though. But once again, that is not supported and we have no intention of merging any 3.x PRs for fixes (3.0.3 came out 13 years ago). We have one final 4.8 beta in the works that we're trying to wrap up now before moving to RC and GA. We need the community's help to get this finished, if you're interested in contributing. Meanwhile, many people have been successfully using the betas in production (with millions of downloads). Be aware that there is currently a performance regression with MMapDirectory, so we recommend using SimpleFS or NIOFS directory in the meantime if you use beta 17. This should be fixed with beta 18.
