Unable to override crypto providers in Mono-2.10.8

Question

I am unable to map my crypto provider to a name in the machine.config file. At first glance everything appears in order, am I overlooking something silly? I'm using Mono-2.10.8

<mscorlib>
    <cryptographySettings>
        <cryptoNameMapping>
            <cryptoClasses>
                <cryptoClass monoMD2="Mono.Security.Cryptography.MD2Managed, Mono.Security, Version=2.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756" />
                <cryptoClass AesProvider="MyProvider.MyAes, MswlAes, Culture='neutral', PublicKeyToken=0738eb9f132ed756, Version=1.0.0.0"/>
            </cryptoClasses>
            <nameEntry name="MD2" class="monoMD2" />
            <nameEntry name="AES" class="AesProvider"/>
            <nameEntry name="AES128" class="AesProvider"/>

Answer 1

It's a bug that was fixed (very) recently where new algorithms / oid could be added but not replaced. It will be part of future Mono 2.10.x releases. Otherwise your machine.config looks right to me.
