You need to adjust the signature to specify the explicit namespace of the Message class:

void WriteSoapMessage(MessageBinding messageBinding, 
    ThreeDSeekUtils.Message message, bool soap12)

or

void WriteSoapMessage(MessageBinding messageBinding, 
    System.Web.Services.Description.Message message, bool soap12)

Whichever is appropriate. Another option is to alias your namespaces in the using block at the top of the class:

using ThreeD = ThreeDSeekUtils;
using ServicesDesc = System.Web.Services.Description;

Then you could use the aliases in shorter form:

void WriteSoapMessage(MessageBinding messageBinding, 
    ThreeD.Message message, bool soap12)

or

void WriteSoapMessage(MessageBinding messageBinding, 
    ServicesDesc.Message message, bool soap12)
