Problem in calling C# DLL in LabVIEW

[五月雪]

I have a problem in calling C# DLL in LabVIEW. The demo in C# can running correctly, can detect the connection of instrument, but it doesn't work in LabVIEW, I don't know what I missed. 

BTW, function StartAsync() was replaced by StartForManufacture() in LabVIEW.

What doesn't work?

Nothing will work for us, we don't have the device...

I'd register the event before connecting, if you register after the event might be missed.

I've tried register the event before connecting, it didn't work either.

My purpose of LabVIEW program is to check the status of the connection between PC and device. 

The function "StartAsync()" is an asynchronous function in the C# project. I don't know if LabVIEW can call an asynchronous function directly, I've tried, and it didn't work anyway.

There's very little we can do without the device and\or a lot more details.

I'd put on retain wire values, run once and see where errors start (highlight execution would work too). And then tell us, because without the device we probably can't run the code like you do.
