使用 c# 表达式的 XAMLX 工作流 [英] XAMLX Workflow with c# expressions

问题描述

我正在 vs2012/.Net 4.5/WF 4.5 中开发自托管工作流，并且很难弄清楚以下消息

I'm developing a self host workflow in vs2012/.Net 4.5/WF 4.5 and having quite a hard time figuring out the following message

表达式活动类型CSharpValue`1"需要编译才能运行.请确保工作流已编译.

Expression Activity type 'CSharpValue`1' requires compilation in order to run. Please ensure that the workflow has been compiled.

当我调用由服务引用生成的活动时会发生此错误(当您添加 WCF 服务引用时，端点上的每个操作都成为一个活动).

This error happens when i call a activity generated by a service reference (When you add a WCF service reference, each action on the endpoint become a activity).

在 MSDN 中环顾四周，我发现了这些文章:

Looking around in MSDN i've came across these articles:

• http://msdn.microsoft.com/en-us/library/ee358749.aspx
• http://msdn.microsoft.com/en-us/library/29110be7-f4e3-407e-8dbe-78102eb21115#CodeWorkflows

他们说

当工作流服务托管在 IIS 或 WAS 中时，则不需要额外的步骤，但如果 XAML 工作流服务是自托管的，则必须编译 C# 表达式

When a workflow service is hosted in IIS or WAS then no additional steps are required, but if the XAML workflow service is self-hosted, then the C# expressions must be compiled

所以，我终于得到了我的问题:我应该怎么做才能按 F5 并调试我的工作流，让它在 IIS 上运行?并停止这个该死的例外......

So, i finally get to my question: What should I do so i can hit F5 and debug my workflow, having it run on IIS? and stop this god damn exception...

我尝试转到项目配置并设置为使用本地 IIS，如下所示:

I've tried to go to the project config and set to use local IIS as follow:

但由于我仍然收到错误，我认为它不起作用...

but since i still get the error i assume it's not working...

推荐答案

尽管文章中提到了在 IIS/WAS 上运行的内容，但我只在我实施了结构建议时才设法运行工作流......这不是答案问题......它更像是一种解决方法......

Despite what the article said about running on IIS/WAS I only managed to run the workflow when I implemented the fabric sugested... this is not an answer for the question... its more like a workaround...
