我正在TFS2013中创建自定义活动,并且我在构建应用程序时遇到以下问题:
An error occurred while initializing a build for build definition \TestApp\TestApp.Main.CI:
Exception Message: Expression of type 'Microsoft.TeamFoundation.Build.Workflow.Activities.BuildSettings' cannot be used for return type 'Microsoft.TeamFoundation.Build.Workflow.Activities.BuildSettings' (type ArgumentException)

你有什么想法？谢谢!
