Hi Naresh,
LinqToRdf can work with any triple store that is able to handle SPARQL
queries. As such if you have a triple store using MySQL, then
LinqToRdf will work with it.
SEMWEB.NET supports MySQL directly, so
your best bet would be to read the documentation on that project and
use it to create an
ASP.NET host (as described in detail in the docs
over there). BTW: If you have LinqToRdf then you will have everything
you need to follow the steps described in the semweb docs.
