For any file you distribute that contains code from the software (in source code or binary format), you must provide recipients the source code to that file along with a copy of this license
Does that mean I have to provide the source code even if I only use the unmodified (original) DLL in binary format? Note that this unmodified DLL contains code from the software, although it was not compiled by me.
What does provide mean? Shall I provide 11 MB of source code as part of my application (install the source on hard disk) or can I provide it as an extra download as well?
Sometimes the reciprocal license is incorrectly interpreted to also
apply to bundles, packages, and custom actions built using the WiX
toolset. The Outercurve Foundation has previously provided this
statement below to clarify which now the .NET Foundation reaffirms:
The WiX toolset (WiX) is licensed under the Microsoft Reciprocal
License (MS-RL). The MS-RL governs the distribution of the software
licensed under it, as well as derivative works, and incorporates the
definition of a derivative work provided in U.S. copyright law.
OuterCurve Foundation (and the .NET Foundation) does not view the
installer packages generated by WiX as falling within the definition
of a derivative work, merely because they are produced using WiX.
Thus, the installer packages generated by WiX will normally fall
outside the scope of the MS-RL, and any of your source code, binaries,
libraries, routines or other software components that are incorporated
in installer packages generated by WiX can be governed by other
