I'm trying to compile the following c# code for a simple WPF GPIB console using VISA. It's essentially taken from "Visa and GPIB App development using C# or VB.net" walkthrough. I have VISA 5.11 installed and I'm referencing the current versions of the .common and .VisaNS files in the VS2010 project, which are 9.1.40.159 and 9.1.40.156, respectively. I get the following errors on the mbSession declaration line at compile-time:
error CS0012: The type 'NationalInstruments.ISynchronizeCallbacks' is defined in an assembly that is not referenced. You must add a reference to assembly 'NationalInstruments.Common, Version=9.0.40.362, Culture=neutral, PublicKeyToken=dc6ad606294fc298'.
error CS0012: The type 'NationalInstruments.ISupportSynchronizationContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'NationalInstruments.Common, Version=9.0.40.362, Culture=neutral, PublicKeyToken=dc6ad606294fc298'.
I'm hesitant to download and include this older version that it's asking for as I want to try to avoid any additional compatibility issues further down the road. Any suggestions?
