Is there a way to exclude assembly members from obfuscation?
Yes, you can use the special assembly NineRays.ObfuscationAttributes.dll which can be found in SDK\Obfuscation Attributes catalog. All you have to do is to include it into your project and use the attributes from this assembly to mark the members with the NotObfuscate attribute. There is no need to include this assembly to distributed packages since the utilized attributes are for reference only.
