I am trying to export a class in LabVIEW 2013 to a .NET Assembly. According to this I can just select the members of the class that I want to export and it will generate a .NET class for them. http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/building_a_net_assembly/ I am able to export the individual members of the class, but when I run the code in .NET it starts searching for mydllname.dll/myclassname.lvclass (the file of the class that the exported members belong to) and can't find it. My next step was to add the class to the the Always Included list, but it seems that when I do that some of the members that I have in the Exported VI's list don't show up in the .NET assembly. The class I'm trying to export is inhereted from another class, so I tried adding both classes to the Always Included list and all of the base class members to the Exported VI's list, but I still have members missing in the .NET classes. Thinking it could be something releated to exporting LVOOP classes, I tried ditching the LVOOP class altogether and rewrote the labview code to use generic VI's and a cluser typedef to store the member data. However, it seems like the labview builder doesn't recognize that the control and indicator clusers that I use to pass the member data belong to the same typedef, so it exports a different .NET class for each control and indicator cluster. This creates a problem because I have no way of passing the output of one funtion to the next in .NET since I cannot convert between the two .NET types. Has anyone had problems like this/know how to fix it??? I couldn't find much online about building a .NET interop assembly beyond the basic configuration steps, so any help would be much appreciated! Thanks
