var launcher = new CMLauncher(new MinecraftPath());

// CMLauncher class create DefaultVersionLoader instance automatically
// MVersionCollection versions = launcher.VersionLoader.GetVersionMetadatasAsync();
MVersionCollection versions = await launcher.GetAllVersionsAsync(); // shortcut

// show all versions
foreach (MVersionMetadata ver in versions)
{
    Console.WriteLine(ver.Type + " : " ver.Name);
}

// Get latest release version name:
Console.WriteLine(versions.LatestReleaseVersion.Name);

// Get latest snapshot version name:

MVersion realVersion = versions.GetVersion("1.15.2");
