サンプル: コードでリアルタイム ワークフローを作成する

 

公開日: 2017年1月

対象: Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online

このサンプル コードは設置型の Microsoft Dynamics 365 に適用されます。 サンプルの完全なソース コードは、SDK Microsoft Dynamics CRM SDK パッケージをダウンロードします。 ダウンロード パッケージの次の場所にあります。

SampleCode\CS\Process\Workflows\CreateRealtimeWorkflow.cs

Microsoft Dynamics CRM SDK パッケージをダウンロードします。

要件

設置型サーバーのカスタム XAML ワークフローのサポートを有効にする必要があります。 詳細については、「XAML ワークフローの有効化または無効化」を参照してください。この SDK で提供するサンプル コードを実行するために必要な要件については、「サンプルとヘルパー コードの使用」を参照してください。

使用例

次のサンプルは、Web アプリケーションの対話型ワークフロー デザイナーを使用する代わりに、コードでリアルタイム ワークフローを作成する方法を示します。 このサンプルは、カスタム XAML ワークフローが Microsoft Dynamics 365 (オンライン)でサポートされていないため Microsoft Dynamics 365 の設置型または IFD (インターネットに接続する展開) でのみ機能します。
