Getting symbol value through ADS throws exception

[drvic10k]

When I am getting the value using observables, I get this exception

I am using version 6.0.207, so the reference of TwinCAT.Ads 6.0.190 is strange

System.TypeLoadException HResult=0x80131522 Message=Method 'get_ErrorStrategy' in type 'TwinCAT.Ads.SumCommand.SumCommandWrapper1' from assembly 'TwinCAT.Ads, Version=6.0.190.0, Culture=neutral, PublicKeyToken=180016cd49e5e8c3' does not have an implementation.

This seems to be the same issue on your local system as #44. The Package dependencies from Version 6.0.207 look ok. Duplicate.
