I have a DLL and VB.NET source code from NIST called REFPROP that work under .NET Framework 3.5. At the same time, I have an application I need to build that uses third party controls from National Instruments that only work under .NET Framework 4.0.
The main application (framework 4.0) contains all of the UI and other functions I need with the exception of calls to the NIST REFPROP to get refrigerant properties.
I am trying to find a way to use the main program (using framework 4.0) to call a second program (the NIST REFPROP using framework 3.5) to get the answers I need.
Typically, you pass a temperature and pressure and refrigerant type to the RefProp routine with a function call for the answer you want and the function result provides the answer.
I am at a loss as to what to do here. Any suggestions?
