we use a .net dll in the project, it works fine in develop environment. after built into application, the application popup a diaglog to select the dll, means it can't load this dll in the data folder automatically. we have searched the forum about loading .net dlls, and tried something, but it doesn't works. https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000PAm6SAG&l=zh-CN https://zone.ni.com/reference/en-XX/help/371361K-01/lvhowto/configuring_clr_version/

LabVIEW

issues on load .net assembly in application

Author

sorry for the confuse.

Putting the sources on the computer?Which sources? Did you write this assembly yourself?

----here, we put the source code of labview project to another computer, not the assembly's source code. so the development environment is totally the same.

Also you claim that all classes in the assembly are static but if that was the case you couldn’t use a constructor node since LabVIEW would have nothing in the assembly that could be instantiated.

----here, means put a construct node of this assembly on the BD in one of the method vi of plc base class.
