Exemplo: Criar um fluxo de trabalho em tempo real no código
Publicado: janeiro de 2017
Aplicável a: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Este código de exemplo aplica-se ao Microsoft Dynamics 365 local. O código-fonte completo do exemplo pode ser encontrado no seguinte local do pacote de Baixe o pacote do SDK do Microsoft Dynamics CRM. do SDK:
SampleCode\CS\Process\Workflows\CreateRealtimeWorkflow.cs
Baixe o pacote do SDK do Microsoft Dynamics CRM.
Requisitos
Você deve ativar o suporte para fluxos de trabalho XAML personalizados no servidor local. Para obter mais informações, consulte Habilitar ou desabilitar fluxos de trabalho do XAML.Para obter mais informações sobre os requisitos necessários à execução do código de exemplo fornecido neste SDK, consulte Usar o código de exemplo e auxiliar.
Demonstra
O exemplo a seguir mostra como criar um fluxo de trabalho em tempo real no código em vez de usar o designer de fluxos de trabalho interativo do aplicativo Web. Este exemplo funciona somente com uma implantação local ou IFD do Microsoft Dynamics 365 porque os fluxos de trabalho XAML personalizados não são suportados no Microsoft Dynamics 365 (online).
