APSL-2.0 in System.Native

[cz-dev-ge]

Hi everyone,
I just noticed that in System.Native there is a folder ios containing some files which are licensed under APSL-2.0.

I have two questions here:

• are those files built into the Windows targeting NuGets/DLLs?
• will I get into trouble linking to them from a closed source project?

As far as I know Apple relicensed some of their APSL-2.0 licensed stuff to Apache-2.0 later.

Best regards

No. Intuitively, these files are only get included when targeting iOS-like platforms.

• will I get into trouble linking to them from a closed source project?

The files are copy-pastes from Apple source. You'd better ask Apple for the licensing.

If you need legal advice about compatibility of software licenses with your closed source project, you need to ask your lawyers.

I asked because in the root README it says ".NET (including the runtime repo) is licensed under the MIT license." and as APSL is a reciprocal license I wondered if this does not effect other parts of the repo.

To clarify: Can I build and distribute closed source software based on .NET without the APSL-2.0 affecting my own code. Especially when targeting iOS?

Best regards.

PS: The code file looks like it has been BSD-3-Clause originally. It might be possible to replace it with the original version without the APSL-2.0 license.
