Looks like there is a load issue when using DLLs from both .net 4.0 and the SIS OSIsoft adapters. You get a runtime error.


The solution is to add the folloing to your app.config file:


<startup useLegacyV2RuntimeActivationPolicy="true">


Not sure all the details of why, but there is a pretty good explanation here:


Hope OSIsoft solves this issue soon, so we do not need this workaround, as it may interfare with other things.
