Unfortunately not.

I am afraid that this is where we have to leave it now. We cannot go further unless .NET Standard 2.1 is supported.

Unfortunately, UWP does not support .NET Standard 2.1 just yet (docs.microsoft.com/en-us/dotnet/standard/net-standard).

Does OPC Labs have a version of this nuget package (5.63.0-rev2) that would still accept .NET Standard 2.0?

Hello.

I have looked a bit deeper into this issue. It is related to the classes that provide support for usage from COM tools and languages, on top of our normal .NET objects. Currently, this is actually only functional in the .NET Framework targeting, not .NET Standard.

So, I have made a first step and changed the "offending" parts in the .NET Standard build of QuickOPC (i.e. refrained from the use of IDispatch), in the current QuickOPC version in development (5.63). But, since we now require .NET Standard 2.1, I got other build problems when trying to build your solution with the updated QuickOPC. It looks like a newer UWP targeting is also necesasary (or that it is not possible to have UWP with .NET Standard 2.1)? We do not do UWP here and it is beyond our expertise.

If you want to try it yourself, you can use the prerelease build on www.nuget.org. The one I have just described is 5.63.0-rev2. If you can upgrade the project to .NET Standard 2.1 but still get issues with QuickOPC, I can take it from there then.

Best regards

Thank you for the quick response. I think we'd be open to upgrading the library if it is compatible with our solution and license, so any help is much appreciated. I just sent a sample solution to This email address is being protected from spambots. You need JavaScript enabled to view it..

Hello.

I do not think that we ever tested with or considered .NET Native as a target, so this is not much of a surprise.
I can have a look of it if you send me a small project that reproduces the problem.

It should be noted, however, that we only make updates or fixes to the currently released last version. So, unless there is some possible workaround, there will be no solution with version 5.59.

Best regards

Release Build Configuration won't compile was created by sjdockendorf08
I have a project built in .NET Standard 2.0 that includes the nuget package OpcLabs.QuickOpc library (5.59.1055). I am able to run the solution in debug mode successfully. However, when I switch it to a release build configuration set to compile with the .NET Native tool chain, I get the error below. We are required to get a working release mode build for our production install of this solution.
