.net - LightSwitch beta 1：“CreateRuntimeExtensionAssembliesManifest”任务意外失败

Question

使用 LightSwitch Beta 1，每次我构建我的项目时，我都会在 ServerGenerated 项目中收到此错误：

The "CreateRuntimeExtensionAssembliesManifest" task failed unexpectedly.
System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.LightSwitch.BuildTasks.Extensions.CreateRuntimeExtensionAssembliesManifest.Execute()
at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute()
at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(ITaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask, Boolean& taskResult)

该项目之前正在构建，我使用 ClickOnce 发布。我试图发布一个新版本，它开始这样做。
