If I understand correctly, you want to use .NET to control what is 
displayed in the map.

First I would make sure that you can not do everything you need using 
mapserver cgi parameter substitution as this might be much simpler.

Assuming that the above will not work, then you are going to have to 
make you mapscript application simulate a WMS service so you can call it 
from OpenLayers.

Now:

data ---> mapserver ----> OpenLayers

In this you would program in JavaScript and change the url for the map 
requests to pass parameters and do parameter substitution in the 
mapfile. This is a standard Web 2.0 approach.

With mapscript:

data ---> your.net -----> OpenLayers

Here you have to simulate a WMS service so you can talk to OpenLayers 
and then read the parameters from OpenLayers to control your .NET code 
and how it interacts with mapserver. Since you have to pass parameters 
to the server anyway, I would start and see if you can do it with the 
existing mapserver code.
