Ni-DAQmx .NET6 Support

[JordanWirth]

For any other developers who find this post, I also built a minimalistic .NET 6.0 C# wrapper around the NI-DAQmx driver.  (The dll is actually named 'nicaiu.dll'.) 

I only needed it to open and close some relays, so that is all I implemented.  Feel free to expand it with the functions you need.  The readme provides some assistance.

I opened a ticket with NI support last week to ask when they plan to have DAQmx support for .NET6 or .NET8, they replied with the following:

DAQmx was expected to include support in the H2 of 2025.
 
This is a possible time frame, but the exact date has not yet been confirmed.
 
Is there anything else I can assist you with?
 
Kind regards,

This sounds great. At the moment must use .NET 4.8.1 application which streams data by gRPC protocol from NI devices to ASP.NET Core web server running on .NET9.

When DAQmx can be directly integrated into new developments, it would be great. Hopefully .NET9 will be supported too.. not just .NET8.

Heyho 🙂 Reviving this post, since we just got .NET10 LTS 😄 I wonder if NI wants to do anything with this? In the mainwhile, I start to dig into LabVIEW gRPC stuff.
(next year we will need to interface/access a legacy LabVIEW app from a .NET10 desktop app,and in long term re-implement everything in .NET/C#)

Just bumping this post again — we also need .NET 8 support.
At the moment, we have been forced to rely on an open-source wrapper (thanks to the creator), which is far from ideal. The only alternative is to wait… but the question is: how long?

Bump. We really need the .net 8 support as well. The open source wrapper is missing lots of functions we need and we don't have resources to write them ourselves. Any reply from NI on this?

Just a hint: Microsoft has done something since .NET 9 to integrate a sort of compatibility layer between .NET (Core) and .NET Framework. Now it is possible to directly reference an old Framework 4.8 DLL (not standard 2.0) that uses NationalInstruments.DAQmx.dll and NationalInstruments.Common.dll. I made a project in .NET 10 and use some counters on X series cards and it works.

I hope this helps but I don't know yet where the limitations are.
And it should not excuse NI for taking such a long time for a clean support (or at least dropping a clear dependable statement).
