Framework Equivalent in MSSQL?

Introduction:
I want to put database based asp.net web site on a windows server.
For the asp.net files there is a free framework that will run the asp.net
files on the server.
The Question:
Is there any free PROGRAM that can run the .mdf and .ldf files on the
server?
And what is the name of that program?
