We have library website written in classic ASP that allows to browse and search by multiple (50+) filter criterias (author, publication year, ISSN ... ). There are lots of security holes and we have only one developer who hardly maintain this ASP-site with some minor features for last 3 years. There are two common user groups - administrators (librarians) and students (5000+) who have books on hands and search for them.
We don't want to rewrite site from scratch, just to use standard free CMS (.net based) and migrate library data and user accounts with minimum effort. What CMS will you suggest?
What do you think of SharePoint? It has out-of-the-box Visual Studio 2010 support so it looks promising (but we have no experience with this CMS)
Thank you in advance.
