Hello.
Using assembly references instead of package references is not supported. I suggest that you do not even try.

If you want a dev machine that is not connected to Internet, you can still do it with NuGet packages. You just need to collect them, store locally, and configure a NuGet package source(s) that are on the local disk.

If you are using the Setup program of QuickOPC, our NuGet packages are already present on your disk in a directory (NuGetPackages) under where the product is installed. So you just need to add a NuGet Package Source (e.g. in Visual Studio) pointing to that directory. However, the transitively referenced packages that our packages depend on will not be on the disk by default, so you need them as well. Try Google for "collect nuget packages locally for offline use" or so.

Best regards

I would prefer to not use the Nuget package, as the dev machine does not have internet access.   I am using vb.net and want to create a simple read and write of some tags to an OPC Server.  I can't seem to determine with dll i am misisng,  in the code "Dim WithEvent easyUACLient as new EAsyUACLient i get an error  : 'An error occurred creating the form. See Exception.InnerException for details.  The error is: The type initializer for 'OpcLabs.EasyOpc.UA.EasyUAClientCore' threw an exception.'   What dlls are required to run QuickOPC UA Client?
