Hello everyone.

I’m sorry for my poor English, but I would like to ask a question about the license.

I have decided to develop a commercial application for the OPC-UA client.

When I checked the library license on Nuget to use Opc.Ua.Client, it was listed as an MIT license.

However, the OPC Foundation License Portal states that it is a dual license of GPLv2.0 and RCL.

I cannot determine whether the license of Opc.Ua.Client is the MIT license or the dual license.

I would like to confirm the following two things.

1. If I am not a corporate member, will the license when using Opc.Ua.Client be the GPLv2.0 license instead of the MIT license?

2. Why is Opc.Ua.Client listed as an MIT license on Nuget?

Thank you in advance.

Are you using the latest NuGet?

This is what the latest says:
https://www.nuget.org/packages…..26/license

You can’t use Opc.Ua.Client without Opc.Ua.Core

Thank you for your answer.
Nuget posted a topic after seeing the following URL:

https://www.nuget.org/packages……Ua.Client

Since Opc.Ua.Client requires Opc.Ua.Core, does that mean it will be dual licensed instead of MIT licensed?
