DacFx DeploymentPlanExecutor OnExecute 未调用

我正在尝试编写一个自定义程序DeploymentPlanExecutor使用 Microsoft 的 DacFx 3.0 但OnExecute-方法从未被调用。

• 如果我使用相同的DeploymentPlanModifier反而，OnExecute()被按预期调用。
• 无论我添加执行器、修改器还是两者，DAC 实际上都已成功部署到数据库。
• 执行者似乎在部署过程中被识别，因为OnApplyDeploymentConfiguration()叫做

不幸的是我找不到任何使用的例子DeploymentPlanExecutor（仅示例DeploymentPlanModifier）并且 DacFx 的文档根本没有帮助。

我的问题是，为什么OnExecute() in the DeploymentPlanExecutor没有被调用，我该如何解决这个问题？

我的代码DeploymentPlanExecutor and DeploymentPlanExecutor:

using System.Collections.Generic;
using Microsoft.SqlServer.Dac.Deployment;

namespace DacTest
{
    // The executor that does not work as expected
    [ExportDeploymentPlanExecutor(ContributorId, "1.0.0.0")] 
    public class Executor : DeploymentPlanExecutor
    {
        public const string ContributorId = "DacTest.Executor";

        protected override void OnApplyDeploymentConfiguration(DeploymentContributorContext context, ICollection<DeploymentContributorConfigurationStream> configurationStreams)
        {
            // Called
        }

        protected override void OnEstablishDeploymentConfiguration(DeploymentContributorConfigurationSetup setup)
        {
            // Not called
        }

        protected override void OnExecute(DeploymentPlanContributorContext context)
        {
            // Not called!
        }
    }

   // The modifier that does work as expected
   [ExportDeploymentPlanModifier(ContributorId, "1.0.0.0")] 
    public class Modifier : DeploymentPlanModifier
    {
        public const string ContributorId = "DacTest.Modifier";

        protected override void OnApplyDeploymentConfiguration(DeploymentContributorContext context, ICollection<DeploymentContributorConfigurationStream> configurationStreams)
        {
            // Called
        }

        protected override void OnEstablishDeploymentConfiguration(DeploymentContributorConfigurationSetup setup)
        {
            // Not called
        }

        protected override void OnExecute(DeploymentPlanContributorContext context)
        {
            // Called!
        }
    }
}

调用部署的代码（必须位于不同的程序集中）：

using (DacPackage dacpac = DacPackage.Load(@"C:\Temp\dac.dacpac"))
{
    DacDeployOptions dacDeployOptions = new DacDeployOptions();
    dacDeployOptions.AdditionalDeploymentContributors = Executor.ContributorId; // + ";" + Modifier.ContributorId;

    DacServices dacServices = new DacServices(connectionString);
    dacServices.Deploy(dacpac, databaseName, true, dacDeployOptions);
}

问题是，您必须明确告诉 DacFx 使用 Executors。不过默认情况下会启用修饰符。

dacDeployOptions.RunDeploymentPlanExecutors = true;
