Opc ua stack + Visual Studio 2003 - .net 4.5|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

If you program in .NET you need to migrate VS as quickly as you can. MS does not support new framework versions in old VS versions.

I have been on projects where the C++ code is built with a much older version of VS than the C# code for this reason.

  

Thanks for the advice, but unfortunately that does not help me.

My development environment is set. I’m stuck with VS2003 and .net 4.5 for an older version of our software.

We have development virtual machines for all historical environments that our code was developed in so I need a sdk for .net 4.5 and vs 2003.

I want to introduce an OPC ua implementation in an older version of our software. I can’t find a compatible opc ua foundation sdk at the moment. I belivee there have been sdks for vs 2003 in the past. I can’t find any downloads for this.

Thanks for taking the time to answer. I’ll give up on getting vs 2003 support. I knew it was a long shot, just hoping there was an older sdk that I could use. The older development environment is there mainly for the C++ language requirements. There is a large legacy codebase that is sensitive to updates to the C language changes.

Getting a sdk that can target .net 4.5 is also something that would be useful. I believe the current one targets .net 4.6.1 or netstandard 2.0. Is there a previous version that targets 4.5? or the net standard equivalent? I know it is old technology, but this project will be installed on old and fixed evnironments and only .net 4.5 is available. Any existing sdk I can use will save me a lot of work. I’m not expecting mircales, just checking my options before proceeding. Apologies for the strange requests!

You do not need to build the C# code with the same VS version as the C code. I have worked on projects with multiple VS versions.

Unified Automation offers 4.5.2 support with VS2015 projects. .NET standard is .NET 4.6.1 or later.

You can’t get .NET4.5.0 support because .NET 4.5.0 has known unpatched security vulnerabilities. The OPC-F has deliberately removed all older versions .NET code specifically because of the security issues. Other vendors will have the same position.

  

Thanks for the information that clears up my questions. That’s really useful thanks.
