Hi Dojo,

After upgrading our DMAs from version 10.4.0-15151 to 10.5.0-16515, an Automation script that was previously working started failing with System.MissingMethodException: Method not found.

The script has the following main using statements:

using Skyline.DataMiner.Automation;
using Skyline.DataMiner.CommunityLibrary.Netinsight.Nimbra;
using Skyline.DataMiner.Core.DataMinerSystem.Automation;
using Skyline.DataMiner.Core.DataMinerSystem.Common;
using Skyline.DataMiner.DeveloperCommunityLibrary.InteractiveAutomationToolkit;

DLLs referenced in the script under the Advanced tab:

C:\Skyline DataMiner\ProtocolScripts\DllImport\newtonsoft.json\13.0.3\lib\net45\Newtonsoft.Json.dll
C:\Skyline DataMiner\ProtocolScripts\DllImport\skyline.dataminer.core.dataminersystem.common\1.1.0.5\lib\net462\Skyline.DataMiner.Core.DataMinerSystem.Common.dll
C:\Skyline DataMiner\ProtocolScripts\DllImport\skyline.dataminer.core.dataminersystem.automation\1.1.0.3\lib\net462\Skyline.DataMiner.Core.DataMinerSystem.Automation.dll
C:\Skyline DataMiner\ProtocolScripts\DllImport\slc.clib.iastoolkit\1.0.7.2\lib\net462\SLC.CLib.IASToolkit.dll
C:\Skyline DataMiner\ProtocolScripts\DllImport\slc.clib.netinsight.nimbra\1.0.0.6\lib\net462\SLC.CLib.Netinsight.Nimbra.dll

The script "Validate" in Cube shows “No errors”, but when I execute it I get the following error:

System.MissingMethodException: Method not found:
'Skyline.DataMiner.Core.DataMinerSystem.Common.IDms
Skyline.DataMiner.Core.DataMinerSystem.Automation.EngineExtensions.GetDms
(Skyline.DataMiner.Automation.Engine)'
at Script.Run(Engine engine)

In the code I am using, for example:

public void Run(Engine engine)
{
IDms dms = engine.GetDms();
...
}

On 10.4.0 this worked without any issues. The error only started appearing after the upgrade to 10.5.0-16515.

I would like to know if you can provide any guidance on what else I should check, or what the correct setup of DLL references/usage should be for this scenario in 10.5.

Thanks!
