Is there a way stop the "." (period) acting as a word breaker in FullText Indexes?
Having followed the link from the comment by Doug Deden:


  It looks like a multi-step process, but there are some promising ideas here: Customize the Behavior of Word Breakers with a Custom Dictionary and Custom WordBreaker for SQL Server Full-text on Stack Overflow.


I've seen that I will need to create a custom dictionary and add the entry 'ASP.Net'. This will ensure normal word breaks aren't applied to this phrase when crawling and/or searching on the full-text index.
