Hi Team,

We are using Opc.Ua.Core.dll and Opc.Ua.Client.dll ( Version 1.3.342 )  in our application . Our application is targeted to .NET framework 4.0. We want our application to use the latest version of the OPC foundation DLLS. We know that OPC foundation has released version 1.04.354.23  on Nov 13 2018.

 

We need clarifications on below questions.

1. Looks we need to  upgrade the .NET framework version of our application to 4.6.1 to support the 1.04 version. Am I correct ?

2. Do we have any document which gives the details about the breakage changes from version 1.03 to version 1.04?

3 What are the things should be taken care while doing the migration from version 1.03 to version 1.04  ?

 

Thanks
Antoni

The .NET stack has been ported to .NETStandard and there numerous significant changes including a requirement to use the task based programming model (TPM). This switch may cause significant problems for existing applications. Especially if your developers are not familiar with with TPM.

I am not aware of any guide but you can post your question on the GitHub repo.

Hi Randy Armstrong,

Thanks for the details. Sure I will post the questions in GitHub for any clarifications.

Looks the OPC foundation .NET standard tool kit works fine in .NET Framework 4.6 . So I assume it is enough to migrate my application to .NET Framework 4.6 . Am I correct? Please confirm.

 

Thanks

Antoni

As I mentioned it is not simple a question of porting to 4.6 since you also have to deal with the TPM which can be an issue for older .NET applications. Search for ".NET Task Based Programming" to get more information.
