Issue with NuGet package prerelease version containing "-"

[domaslasauskas]

Paket on Windows omits version after and including second "-" in prerelease version number. This results in issue when trying to update from 3.0.0-alpha-0008 to 3.0.0-alpha-0009 as Paket finds MyPackage.3.0.0-alpha.nupkg in cache and just restores previous version instead of new one.

This is was I get in the log when restoring package:

Downloading MyPackage 3.0.0-alpha-0008 to C:\Users\username\AppData\Local\NuGet\Cache\MyPackage.3.0.0-alpha.nupkg

Paket should maintain whole version when storing downloaded packages in cache.

Having hyphen (actually minus) in pre-release version part is allowed according to SemVer and not forbidden anywhere in NuSpec that I could find. From SemVer:

A pre-release version MAY be denoted by appending a hyphen and a series of dot separated identifiers immediately following the patch version. Identifiers MUST comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-].

Issue seems to be originating here:

Paket/src/Paket.Bootstrapper/NugetDownloadStrategy.cs

Line 87 in 0f590df

var dashSplitted = version.Split('-', '+');

As a workaround one could use paket restore --force.

No that's the bootstrapper. The issue is probably in similar code in
Paket.Core project

Sorry, here is the code from Paket.Core:

Paket/src/Paket.Core/SemVer.fs

Line 132 in 8a6bbb5

let dashSplitted = version.Split([|'-'; '+'|])

should be fixed. could you please retry?

Now it works fine. Cheers!
