Amostra: Criar um fluxo de trabalho no código
Publicado: novembro de 2016
Aplicável a: Dynamics CRM 2015
Este código de exemplo é para o Atualização do Microsoft Dynamics CRM 2015 e Microsoft Dynamics CRM Online 2015.Baixe o pacote do SDK do Microsoft Dynamics CRM. Pode ser encontrado no seguinte local no pacote de download:
SampleCode\CS\Process\Workflows\CreateAWorkflow.cs
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 assíncrono de forma programática no código em vez de usar um editor de fluxo de trabalho ou fornecedor. Este exemplo funciona somente com uma implantação local do Microsoft Dynamics CRM 2015, já que os fluxos de trabalho do XML personalizados não têm suporte no Microsoft Dynamics CRM Online.
