Constructor on type 'Microsoft.Win32.SafeHandles.SafeRegistryHandle' not found

Question

After upgrading Fax.NET project to .NET 4 Client Profile i got this Exception:

MissingMethodException:
Constructor on type 'Microsoft.Win32.SafeHandles.SafeRegistryHandle' not found.

Exception occurred on return statement of this function:

private static SafeHandle CreateRegistrySafeHandle(IntPtr handle)
{
    Type type;

    type = typeof(SafeHandle).Assembly.GetType("Microsoft.Win32.SafeHandles.SafeRegistryHandle");

    return (SafeHandle)Activator.CreateInstance(
        type,
        BindingFlags.Instance | BindingFlags.NonPublic,
        null,
        new object[] { handle, true },
        null);
}

What is solution for this exception?

Answer 1

The SafeRegistryHandle Constructor is public ( BindingFlags.Public ) since .NET 4, not internal or private ( BindingFlags.NonPublic ).

If you have access to the source code, you can replace the method with

private static SafeHandle CreateRegistrySafeHandle(IntPtr handle)
{
    return new SafeRegistryHandle(handle, true);
}
