Detect the Visual Studio version inside a VSPackage

Question

How can I check/detect which Visual Studio version is running under my VSPackage?

I cannot get from the registry because the computer could have several versions installed, so I guess there is an API that is able to get it.

Anybody knows how to get it from a managed Visual Studio package using C#?

Finally I wrote a class to detect the Visual Studio version. Tested and working:

public static class VSVersion
{
    static readonly object mLock = new object();
    static Version mVsVersion;
    static Version mOsVersion;

    public static Version FullVersion
    {
        get
        {
            lock (mLock)
            {
                if (mVsVersion == null)
                {
                    string path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "msenv.dll");

                    if (File.Exists(path))
                    {
                        FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(path);

                        string verName = fvi.ProductVersion;

                        for (int i = 0; i < verName.Length; i++)
                        {
                            if (!char.IsDigit(verName, i) && verName[i] != '.')
                            {
                                verName = verName.Substring(0, i);
                                break;
                            }
                        }
                        mVsVersion = new Version(verName);
                    }
                    else
                        mVsVersion = new Version(0, 0); // Not running inside Visual Studio!
                }
            }

            return mVsVersion;
        }
    }

    public static Version OSVersion
    {
        get { return mOsVersion ?? (mOsVersion = Environment.OSVersion.Version); }
    }

    public static bool VS2012OrLater
    {
        get { return FullVersion >= new Version(11, 0); }
    }

    public static bool VS2010OrLater
    {
        get { return FullVersion >= new Version(10, 0); }
    }

    public static bool VS2008OrOlder
    {
        get { return FullVersion < new Version(9, 0); }
    }

    public static bool VS2005
    {
        get { return FullVersion.Major == 8; }
    }

    public static bool VS2008
    {
        get { return FullVersion.Major == 9; }
    }

    public static bool VS2010
    {
        get { return FullVersion.Major == 10; }
    }

    public static bool VS2012
    {
        get { return FullVersion.Major == 11; }
    }
}
