Question

I have a simple custom work item control that works flawlessly in VS 2013. I recently installed VS 2015 on my Windows 10 box and the control throws an error like so:

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

This is frustrating because the control does implement IWorkItemControl Interface. Also compiling to a version of Visual Studio doesn't seem to be a thing, at least as far as I understand it.

I tried to create a very simple control (just a ComboBox on a screen) to do some testing and I got exactly the same error.

I guess I have a couple questions:

Should I be doing this type of custom control in Visual Studio anymore? Or should I be creating web controls to replace what was once done in Visual Studio.
Is there something I'm doing terribly wrong which is causing this to fail?

The very simple control code I created is below, I'm happy to answer questions about my environment if that information is useful.

Thanks for your time and attention.

UserControl Code Behind (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;
        }
    }
 }

UserControl Designer Code:

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;
    }
}

您需要编译一个针对TFS 2015二进制文件的自定义控件版本，以便在VS 2015中加载控件。
