License of 3.8

[ksrangarajan]

We are using the component with the current version of 3.4.0 to support our requirements.

Now, we want to migrate our code to v 3.8.0 (using the code (https://github.com/xceedsoftware/wpftoolkit/archive/refs/tags/3.8.0.zip).

We noticed the license is marked as
Microsoft Public License (Ms-PL) as published at https://github.com/xceedsoftware/wpftoolkit/blob/master/license.md

Is it allowed to use version 3.8 with patching our changes for any issues without purchasing the license or use the earlier version of 3.7 (code at https://github.com/xceedsoftware/wpftoolkit/archive/refs/tags/3.7.0.zip)? Like to know whether it invite any legal hassles?

I don't know this forum is the right place to raise such queries. If not, please let me know the appropriate forum or contact to clarify such issues.

Hi,
Yes, you can use v3.8 for free.
Starting at v4.0, the Toolkit it offered under the Xceed Community License agreement(for non-commercial use).
If you have any questions regarding the licensing, I invite you to contact Xceed at [email protected].
Thank you.

Hello jogibear9988,

Yes The OpenSource version of the Toolkit is free to use. That has not changed.
Only the Plus edition can be bought.

Thank you.

Note this more recent comment on another thread which clarifies the licensing of the versions around 3.8:
#1557 (comment)

3.6.0 and before are MS-PL.
3.7.0, 3.8.0 and 3.8.1 were released with the Xceed License.
Then we decided to offer one last version under MS-PL : v3.8.2.
Then, starting at v4.0, all the following versions use the Xceed License (for non-commercial use).

So if you want to use an MS-PL version, use the latest one with that license(v3.8.2) and if you want an up to date version, use the v4.0+ versions (under the Xceed license).
