visual-studio - 自定义工作项控件在 Visual Studio 2015 TFS 2013 中不起作用

Question

我有一个简单的自定义工作项控件，可以在 VS 2013 中完美运行。我最近在我的 Windows 10 机器上安装了 VS 2015，该控件抛出如下错误:

TF400939: The custom control type 'TimSheetsControl.WITimeSheetControl' does not implement the IWorkItemControl interface or is compiled for a different version of Visual Studio.

这令人沮丧，因为控件确实实现了 IWorkItemControl 接口(interface)。编译成一个版本的 Visual Studio 似乎也不是问题，至少据我所知是这样。

我试图创建一个非常简单的控件(只是屏幕上的一个 ComboBox)来进行一些测试，但我得到了完全相同的错误。

我想我有几个问题:

1. 我是否应该再在 Visual Studio 中执行此类自定义控件？或者我应该创建 Web 控件来替换曾经在 Visual Studio 中完成的操作。
2. 是不是我做错了什么导致失败？

我创建的非常简单的控制代码如下，如果该信息有用，我很乐意回答有关我的环境的问题。

感谢您的时间和关注。

用户控件背后的代码(WITimeSheetControl):

namespace TimSheetsControl
{
    public partial class WITimeSheetControl : UserControl, IWorkItemControl
    {
        private object WorkItemDataSource;
        protected IServiceProvider ServiceProvider = null;
        public WITimeSheetControl()
        {
            InitializeComponent();
        }

        public StringDictionary Properties{get; set;}

        public bool ReadOnly { get; set; }

        public object WorkItemDatasource
        {
            get
            {
                return WorkItemDataSource;
            }

            set
            {
                WorkItemDataSource = value;
            }
        }

        public string WorkItemFieldName { get; set; }

        public event EventHandler AfterUpdateDatasource;
        public event EventHandler BeforeUpdateDatasource;

        public void Clear()
        {

        }

        public void FlushToDatasource()
        {
        }

        public void InvalidateDatasource()
        {
            if (string.IsNullOrEmpty(WorkItemFieldName))
            {
                throw new ArgumentNullException("The fieldname property for the WITimeSheetControl is not set.");
            }

            cmbPosition.SelectedIndex = -1;
        }

        public void SetSite(IServiceProvider serviceProvider)
        {
            ServiceProvider = serviceProvider;
        }
    }
 }

用户控件设计器代码:

namespace TimSheetsControl
{
    partial class WITimeSheetControl
    {
        /// <summary> 
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary> 
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Component Designer generated code

        /// <summary> 
        /// Required method for Designer support - do not modify 
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.cmbPosition = new System.Windows.Forms.ComboBox();
            this.SuspendLayout();
            // 
            // cmbPosition
            // 
            this.cmbPosition.DropDownWidth = 145;
            this.cmbPosition.FormattingEnabled = true;
            this.cmbPosition.Items.AddRange(new object[] {
            "Business Analyst",
            "Programmer"});
            this.cmbPosition.Location = new System.Drawing.Point(139, 23);
            this.cmbPosition.MaximumSize = new System.Drawing.Size(165, 0);
            this.cmbPosition.Name = "cmbPosition";
            this.cmbPosition.Size = new System.Drawing.Size(151, 21);
            this.cmbPosition.TabIndex = 0;
            // 
            // WITimeSheetControl
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.Controls.Add(this.cmbPosition);
            this.Name = "WITimeSheetControl";
            this.Size = new System.Drawing.Size(1219, 565);
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.ComboBox cmbPosition;
    }
}

您需要编译一个以 TFS 2015 二进制文件为目标的自定义控件版本，以便您的控件在 VS 2015 中加载。
