Gapotchenko.FX.Versioning.Semantic 2026.7.2

Overview

The module provides semantic versioning functionality that follows the Semantic Versioning 2.0.0 specification.

SemanticVersion

SemanticVersion record from Gapotchenko.FX.Versioning.Semantic module represents a semantic version with support for major, minor, patch, prerelease, and build metadata components.

Creating a Semantic Version

You can create a SemanticVersion in several ways:

using Gapotchenko.FX.Versioning;

// Using constructor with major, minor, and patch
var version1 = new SemanticVersion(1, 2, 3);

// With prerelease and build metadata
var version2 = new SemanticVersion(1, 2, 3, "alpha.1", "20240101");

// From a version string
var version3 = new SemanticVersion("1.2.3-alpha.1+20240101");

// Using Parse method
var version4 = SemanticVersion.Parse("2.0.0-beta.2");

Parsing

The Parse method converts a string representation of a semantic version to a SemanticVersion object:

using Gapotchenko.FX.Versioning;

var version = SemanticVersion.Parse("1.2.3-alpha.1+20240101");
Console.WriteLine($"Major: {version.Major}, Minor: {version.Minor}, Patch: {version.Patch}");
Console.WriteLine($"Prerelease: {version.Prerelease}, Build: {version.Build}");

For scenarios where the input might be invalid, use TryParse:

if (SemanticVersion.TryParse("1.2.3", out var version))
 Console.WriteLine($"Parsed version: {version}");
else
 Console.WriteLine("Invalid version string");

Version Components

A SemanticVersion exposes the following properties:

• Major: The major version number
• Minor: The minor version number
• Patch: The patch version number
• Prerelease: The prerelease identifier (e.g., "alpha.1", "beta.2", "rc.1")
• Build: The build metadata (e.g., "20240101", "abc123")

using Gapotchenko.FX.Versioning;

var version = new SemanticVersion(1, 2, 3, "alpha.1", "20240101");

Console.WriteLine(version.Major); // 1
Console.WriteLine(version.Minor); // 2
Console.WriteLine(version.Patch); // 3
Console.WriteLine(version.Prerelease); // "alpha.1"
Console.WriteLine(version.Build); // "20240101"

Comparison

SemanticVersion implements IComparable<SemanticVersion> and supports standard comparison operators:

using Gapotchenko.FX.Versioning;

var v1 = new SemanticVersion(1, 2, 3);
var v2 = new SemanticVersion(1, 2, 4);
var v3 = new SemanticVersion(1, 2, 3, "alpha.1");

Console.WriteLine(v1 < v2); // True
Console.WriteLine(v1 > v3); // True (release version is greater than prerelease)
Console.WriteLine(v1 == v2); // False

Prerelease versions are considered less than release versions:

var release = new SemanticVersion(1, 0, 0);
var prerelease = new SemanticVersion(1, 0, 0, "alpha.1");

Console.WriteLine(release > prerelease); // True

Conversion to System.Version

SemanticVersion can be implicitly converted to System.Version:

using Gapotchenko.FX.Versioning;
using System;

var semanticVersion = new SemanticVersion(1, 2, 3, "alpha.1", "20240101");
Version version = semanticVersion; // Implicit conversion

Console.WriteLine(version); // "1.2.3"

Note that the conversion is lossy because System.Version does not support prerelease or build metadata.

Conversion from System.Version

You can create a SemanticVersion from a System.Version:

using Gapotchenko.FX.Versioning;
using System;

var version = new Version(1, 2, 3);
var semanticVersion = new SemanticVersion(version);

Console.WriteLine(semanticVersion); // "1.2.3"

Deconstruction

SemanticVersion supports deconstruction for easy extraction of version components:

using Gapotchenko.FX.Versioning;

var version = new SemanticVersion(1, 2, 3);

// Deconstruct to major and minor
var (major, minor) = version;

// Deconstruct to major, minor, and patch
var (major2, minor2, patch) = version;

String Formatting

SemanticVersion provides a ToString() method that returns the standard semantic version string format:

using Gapotchenko.FX.Versioning;

var version = new SemanticVersion(1, 2, 3, "alpha.1", "20240101");
Console.WriteLine(version.ToString()); // "1.2.3-alpha.1+20240101"

Type Converter

SemanticVersion includes a TypeConverter that enables seamless integration with various .NET components:

using Gapotchenko.FX.Versioning;
using System.ComponentModel;

var converter = TypeDescriptor.GetConverter(typeof(SemanticVersion));
var version = (SemanticVersion)converter.ConvertFrom("1.2.3");
