c# - 未调用 DacFx DeploymentPlanExecutor OnExecute

Question

我正在尝试使用 Microsofts DacFx 3.0 编写自定义 DeploymentPlanExecutor，但从未调用 OnExecute 方法。

• 如果我改用相同的 DeploymentPlanModifier，则会按预期调用 OnExecute()。
• 无论我是添加执行器、修改器还是两者，DAC 实际上都已成功部署到数据库中。
• Executor 似乎在部署期间被识别，因为调用了 OnApplyDeploymentConfiguration()

不幸的是，我找不到任何使用 DeploymentPlanExecutor 的示例(只有使用 DeploymentPlanModifier 的示例)并且 DacFx 的文档根本没有帮助。

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

我的 DeploymentPlanExecutor 和 DeploymentPlanExecutor 的代码:

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(必须在不同的程序集中):

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 使用执行器。不过默认情况下会启用修饰符。

dacDeployOptions.RunDeploymentPlanExecutors = true;
