How to Update the C# dll in LabView

[CODERED]

Hi.,

 i created C# dll with "ADD"  Function. in that dll contains only that function. for that function i am passing two variables.

 "public int Add(int A, int B) "

 

in the Labview, i use the .NET constructor(Drag and drop the node and in the dialog box i browse the .net dll) and Invoke node to access the

 

method it's working fine..

 

Now the Problem, After build the dll i added some more function in the c# dll.

"public int Sub(int A, int B) "

In the labview i can't see the new method in the "Invoke Node". so in the ".NET Constructor" dialog box i browsed the same dll but i got the Message "The version of assembly you requested was automatically  promoted to a newer version by the .net runtime engine"

the newer version of the dll not updating. How to get the newly added function.

 
Please help to fix this problem

Have you tried to browse again your updated dll in the "Select a constructor.." dialog box?

Have you tried to call the new function of your dll in another .NET langage (C# for example)?

I tried in the labview but is't says the message "The version of assembly you requested was automatically  promoted to a newer version by the .net runtime engine"

i tried in the other c# project in the same dll it's working. i tried to decompile the dll and i see the code., the new function is there.

Try to delete the constructor, save the VI, add a new constructor and select your dll again.

It's a workaround proposed here : http://forums.ni.com/ni/board/message?board.id=170&thread.id=229618

Yes. i tried that one. not working..

i closed the whole labview and create the new Vi  that time also the same problem.

Accidentally my system restarted after i created new VI and browse the dll it's working.... so i add again new function to the dll and checked same issue is coming.... i am getting same Message...

i am not able to get what is the mistake!!!!

Do you tried to increase the version number of your assembly (LVCall 1.0.0.1 for example)?

[CODERED]

yes. i tried that one also.

every time building the C# dll i am increasing the Version no... but no luck.....

Anyone ever figure this out?

I've got Labview code that is calling a DLL and that DLL I update frequently.  Very slow and frustrating process.

Hi I has the same problem with my C# DLL.

(I'm lucky I don't have to update it frequently).

If I remember correctly in order to use the new defined functions I had to

1) Remove constructor nodes and save the VI

2) Exit labview

3) Restart Labview and replace a new constructor node.
