WiX should work with >MAX_PATH paths

.NET doesn't support long file names. Fixing this would require abstracting all the i/o and P/Invoke-ing to Win32 equivalents.

It looks like .NET recently discarded the MAX_PATH constraint.

Yes. Now we just need Windows to fix the MSI APIs MAX_PATH limitations.

Good to know, thanks for the update Rob.

We did everything we could to enable long path support in .NET and Windows in WiX v4.0 for #5314.
