Consider dual-licensing under Apache 2.0?

[lilith]

The MS-PL is incompatible with many free software licenses, as it imposes a unique restriction:

(D) If you distribute any portion of the software in source code form, you may do so only under this license by including a complete copy of this license with your distribution. [...]

Many OSI-approved copyleft licenses require that linking or interacting code must be licensed in a manner that does not further restrict user rights. This conflicts with the MS-PL as it specifically prohibits the right to re-license.

There are many GPL, LGPL, and AGPL-licensed libraries - yet we are forced to choose between using them - and using this library. We are also prevented from using any copyleft license in software which depends on RazorEngine.

Dual-licensing (or-relicensing) under Apache 2 would solve this. As GitHub notifies people who are mentioned, re-licensing would involve pasting the list of contributors into this thread and asking for a release of their copyright. Getting approval can take anywhere from a few days to several months, depending upon contributor awareness.

Thoughts?

I think this is a good idea and currently have a change in my local branch to change to the Apache 2 license as used by ASP.NET.

I'm not sure why I originally added the MS-PL license, it was just a mistake.

Great, thanks! If anyone has contributed code under the Ms-PL, they will need to sign-off on the license change - typically in the form

I hereby release all of my contributions to this project under the terms of the Apache 2 license.
