QUESTION
my goal is to write a small OPC-UA-Client in Delphi and i want to use the original OPC-UA-Stack without any 3rd-party-SDK.
I am already able to compile the Ansi-C-Stack but the output are .obj and .lib files.
Is there a way to compile the stack to a DLL? I already tried do use link.exe to create a DLL from the Obj-Files but I get a lot of "unresolved external symbol" error messages, some of them i was able to resolve, but not all.
I also tried to use the obj. files directly in delphi, but then i have a lot of manual translation work.
...ANSWER
Answered 2018-Jun-25 at 08:19Yes, you can compile it as a DLL with Visual Studio. In the project Properties, change the Configuration Type to .dll and also add the define '_UA_STACK_BUILD_DLL'.
QUESTION
I have been in process of developing an application in C#.NET which can communicate to PLC through OPC server. I have searched for C#.NET based OPC client libraries for it and found below ones. As I have never used any of these libraries I don’t know which can be a first choice. Price do not matter much here. If you guys have used any of them or any other, please advise me.

...ANSWER
Answered 2017-Mar-13 at 19:14take a look a the OPC Fondation Github. There two stacks for .Net OPC UA client developments. One for regular .Net and a new one for .Net Standard. Both are not totally compliant. You can also take a look at OpenOpcUa.org this the most advance Open Source project for OPC UA and the Only one certified by the OPC Foundation CTT. But it's C/C++
I hope it helps Regards Michel
