I'm using DIS on VS2017 to develop an automation script from scratch.

I used the following option to create an Automation Script solution and just added some code.

As soon as I try to publish on my DMA I'm getting the following error:

System.MissingMethodException:
Message="Method not found: 'System.Collections.Generic.IEnumerable`1<System.ValueTuple`2<System.String,System.String>> Skyline.AppInstaller.AppPackageAutomationScriptBuilderHelper.ExtractAssemblies(Byte[], System.Collections.Generic.IEnumerable`1<System.String>)'."
Source="SLDisCompiler"
StackTrace:

This error still shows up when I comment all the code, so should be some setting on DIS that is raising it. Can anyone please advise?
