How do I create an ASP.NET website to search MLS or IDX listings?
<p>How do I create an ASP.NET website to search <a href="http://en.wikipedia.org/wiki/Multiple_Listing_Service" rel="nofollow">MLS</a> or <a href="http://en.wikipedia.org/wiki/Internet_Data_Exchange" rel="nofollow">IDX</a> listings for a real estate website? I'm assuming there is a C# library to do this?  I'm curious about any pitfalls or unexpected expenses people have ran into in using these services?</p>
