活动和设计师支持

问题描述

我创建了一个抽象的通用基本活动，我从中创建了许多其他活动，我在下面提供了一个简化的代码示例来说明问题：

I created an abstract generic base activity from which I create a number of other activities, I've provided a simplified code sample below to illustrate the problem:

namespace ActivityLibrary
{
	public abstract partial class ActivityBase<T> : SequenceActivity
	{
		public ActivityBase()
		{
			InitializeComponent();
		}
	}
}

从此活动继承的每个活动都没有设计师支持，这有点令人讨厌。为了解决这个问题，我最初设计了从SequenceActivity派生的子活动，然后将基类更改为ActivityBase。但是，设计器支持在XOML + CodeBehind工作流中仍然可以正常工作。

但这不是更糟糕的问题 - 一旦我将基本活动类移动到一个单独的项目而不是继承它的活动，工作流设计师试图包含从基本活动中获得的任何活动，这对我来说是个大问题。

以下是样本派生活动的代码：

Every activity that inherits from this activity does not have designer support, which is mildly annoying. To get around this I initially design the child activities derived from SequenceActivity, then change the base class to ActivityBase. However, designer support still works fine in the XOML+CodeBehind workflows.

But this isn't the worse problem - once I move the base activity class to a separate project than the activities which inherit it, the workflow designer breaks trying to include any of the activities that derive from the base activity, which is a big deal to me.

Here's the code for a sample derived activity:

public partial class ActivityBaseInherited : ActivityBase<object>
    {
        public ActivityBaseInherited()
        {
            InitializeComponent();
        }
    }

// Designer File:
namespace ActivityLibrary
{
    public partial class ActivityBaseInherited
    {
        #region Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        [System.Diagnostics.DebuggerNonUserCode]
        private void InitializeComponent()
        {
            this.CanModifyActivities = true;
            this.getRelocationActivity1 = new ActivityLibrary.GetRelocationActivity();
            //
            // getRelocationActivity1
            //
            this.getRelocationActivity1.Name = "getRelocationActivity1";
            //
            // ActivityBaseInherited
            //
            this.Activities.Add(this.getRelocationActivity1);
            this.Name = "ActivityBaseInherited";
            this.CanModifyActivities = false;

        }

        #endregion

        private GetRelocationActivity getRelocationActivity1;
    }
}

我是否有办法让至少工作流设计师工作，同时仍然将基类分成不同的项目，并且最好得到派生的活动设计师也可以工作吗？

Is there a way I can make at least the workflow designer work while still separating the base class into a different project and preferrably get the derived activity designers to work as well?
