A Semantic Version Library for .Net

This library implements the SemVersion class, which complies with v2.0.0 of the spec from semver.org.

API docs for the most recent release are available online at semver-nuget.org.

Installation

With the NuGet console:

Install-Package semver

Parsing

var version = SemVersion.Parse("1.1.0-rc.1+e471d15", SemVersionStyles.Strict);

Constructing

var v1 = new SemVersion(1, 0);
var vNextRc = SemVersion.ParsedFrom(1, 1, 0, "rc.1");

Comparing

if (version.ComparePrecedenceTo(vNextRc) == 0)
    Console.WriteLine($"{version} has the same precedence as {vNextRc}");

if (version.CompareSortOrderTo(vNextRc) > 0)
    Console.WriteLine($"{version} sorts after {vNextRc}");

Outputs:

1.1.0-rc.1+e471d15 has the same precedence as 1.1.0-rc.1
1.1.0-rc.1+e471d15 sorts after 1.1.0-rc.1

Manipulating

Console.WriteLine($"Current: {version}");
if (version.IsPrerelease)
{
    Console.WriteLine($"Prerelease: {version.Prerelease}");
    Console.WriteLine($"Next release version is: {version.WithoutPrereleaseOrMetadata()}");
}
