MSFSVariableService broken?

Recommended Posts

First of all thanks for this nice FSUIPC c# client. Normally it works without any problem.

I'm programming an interface for a home cockpit. So I often need to scan LVARs or changes of them. I thought that the MSFSVariableService is exactly what I am looking for. After copying most of the code from the Example Code (V1.4) it didn't work (LVAR list empty even if .Init(), .Start(), .Reload() was called). Therefore I executed the example code .exe. Seems to be the exact same problem:

(after clicking on "Log LVars")

[INFO]: **** Starting FSUIPC7 WASM Interface (WAPI) version 0.9.0 (WASM version 0.9.0)
[INFO]: Connected to MSFS
[INFO]: We have 000 lvars:

All comboboxes and textfields are empty.


Tested with FlyByWire A320Neo.

FSUIPC -> Add-ons -> WASM -> List Lvars

works as expected.

You seem to be using an old version of the WASM/WAPI - latest version is:


   133609   [INFO]: **** Starting FSUIPC7 WASM Interface (WAPI) version 1.0.3 (WASM version 1.0.2) using connection -1

In later version of the WASM/WAPI, you don't need to reload as lvars are automatically pushed to clients when discovered.

Presumably there is a later version of Pauls';s ,Net client dll that can be used (probably using WAPI 1.0.2), so you should update. And update your WASM version (and FSUIPC) to the latest version before anything else.

You are absolutely right. I thought updating FSUIPC is sufficient and completely forgot, that your DLL was also updated...

My WASM module was on version 1.0.2 (manifest.json) but with the old FSUIPC_WAPID.dll it logged 0.9.0 🤷‍♂️.

After switching to the new DLL it worked instantly and logged 1.0.2.


Thanks a lot for your quick help
