[MovGP0]

by removing the monoandroid lines, the packages get restored and result in the error message

Paket failed with:
        Unknown .NET moniker >= xamarinios

[matthid]

Seems like a mono bug as https://github.com/fsprojects/Paket/blob/master/src/Paket.Core/FrameworkHandling.fs#L335 contains monoandroid

Will take a look later, can you run with -v (verbose)?

[MovGP0]

after removing both, the lines containing monoandroid and the lines with xamarinios, everything worked fine. haven't tried using the --verbose option.

[matthid]

@forki I cannot figure out what optimizeRestrictions is supposed to do (https://github.com/fsprojects/Paket/blob/master/src/Paket.Core/Requirements.fs#L156) but apparently currently it has problems with the atleast operator.

@MovGP0 apparently paket has problems with the atleast (>=) operator. What exactly did you thought paket would do? Using all Platforms supported by monoandroid (which would be quite similar to >= net45)?

[matthid]

(I thought this would be related to my latest patch, but it isn't)

[forki]

fixed in latest paket 5 alpha
