Após migração de Framework cliente WCF recebe contract mismatch error

Question

Bom dia

Migramos uma aplicação WCF  do .NET Framework 3.5 para o 4.6.2. Não mexemos em nenhum método exposto para os clientes. Porém os clientes passaram a receber erro de contract mismatch. Ao examinar os wsdl descriptions, notei diversas diferenças. Na versão antiga são gerados 2 arquivos wsdl ao criar uma referência no cliente, enquanto na nova versão gera apenas 1. Alguns namespaces mudaram (foram para o default tempuri.org). Segue abaixo assinaturas :

Gostaria de saber se existe alguma maneira de manter a assinatura compatível, para evitar a atualização dos clientes, que são muitos.

Obrigado
