Failed to grant minimum permission requests loading NationalInstruments.Common.Native on medium trust ASP.NET hosting

hello word!

I'm installing a web application which use NationalInstruments.UI.WaveFormGraph on a standard IPS windows hosting service.

As the most IPS, also my IPS implements ASP.NET 2.0 in Medium Trust level and does not allow application override.

This level is not enought to load NationalInstruments.Common.Native.dll or some dependent file.

The following is the thrown exception:

Server Error in '/' Application.

Required permissions cannot be acquired.

1) It seems need the Full Trust level <trust level="Full" originUrl="" /> in web.config but this is disallowed by IPS!
Is it true?

2) Someone had published application using National's ASP.NET dll on a standard IPS?

Thank you
