Thank you for letting me know. In fact, I do not expect much (if any) issues supporting .NET 5, when it goes strictly about the runtime behavior of the OPC parts.

What might be going to be a challenge will be the "newly written" .NET 5 parts (that were not in .NET Core 2.x-3.x) - I mean the Windows Forms and WPF, and their designer support in Visual Studio. We have features in QuickOPC (such as Live Binding) that rely on this and that we would like to continue having in .NET 5, but from what I know so far things are not that smooth in this respect.

Best regards

I'm looking forward to the update, but I understand that it can take a while.
At the moment I have a running .Net 5 test application; no problems until now.

Hello,
that's good, thank you for update.

Officially, however, .NET 5 is not supported though - we have not even made any tests.

.NET 5 support will probably come during 2021, but I do not have more precise date for you.

Best regards

It seems that there was a typo in my embedded managed resource test.
The license info is recognized in a .Net 5 application when i use the ResourceLicensingManagement.Instance.RegisterManagedResource method!

Best regards,

Thanks for your reply.
Are there any expectations when .Net 5 will be supported?

Best regards,

Hello.

1. QuickOPC (up to the current version, 2020.3) is not supported on .NET 5. opclabs.doc-that.com/files/onlinedocs/QuickOpc/2020.3/User%2...me.html#dotNET%20Runtimes.html
2. License Manager only shows the licenses stored in the registry, but they are not being read if you target .NET Standard: opclabs.doc-that.com/files/onlinedocs/QuickOpc/2020.3/User%2.../webframe.html#Licensing3.html

Best regards

Hi support,

I created a Net5.0 application using the latest OpcLabs Nuget libraries. Although I have a valid license (according to the license manager), my application doesn't recognize the license.
I also tried tried the Managed Resource License Store option, but that also failed.
See the attached screen shots.
(No issues with .Net Framework 4.8 )

Windows 10
VS2019 16.8.3
QuickOpc 5.59.492

Hope you can help me..

Best regards,
Goos van Beek.
