An exception does not propagate correctly to the calling function in a Windows Forms application project in Visual Studio .NET (836674)

MORE INFORMATION

Steps to reproduce the behavior

1. Start Visual Studio .NET.
2. On the File menu, point to New, and then click Project. The New Project dialog box appears.
3. Under Project Types, click Visual C# Projects. Under Templates, click Windows Application projects. Click OK. By default, a form that is named Form1 is created.
4. Switch to the code view.
5. In the Form1 form, replace the existing code with the following code.

   using System;
   using System.Drawing;
   using System.Collections;
   using System.ComponentModel;
   using System.Windows.Forms;
   using System.Data;
   
   namespace WindowsApplication1
   {
   	/// <summary>
   	/// Summary description for Form1.
   	/// </summary>
   	public class Form1 : System.Windows.Forms.Form
   	{
   		private System.Windows.Forms.Button button1;
   		/// <summary>
   		/// Windows Form Designer requires this variable.
   		/// </summary>
   		private System.ComponentModel.Container components = null;
   
   		public Form1()
   		{
   			//
   			// Windows Form Designer requires this method.
   			//
   			InitializeComponent();
   
   			//
   			// TODO: Add any constructor code after InitializeComponent call.
   			//
   		}
   
   		/// <summary>
   		/// Clean up any resources that are being used.
   		/// </summary>
   		protected override void Dispose( bool disposing )
   		{
   			if( disposing )
   			{
   				if (components != null) 
   				{
   					components.Dispose();
   				}
   			}
   			base.Dispose( disposing );
   		}
   
   		#region Windows Form Designer generated code
   		/// <summary>
   		/// Windows Form Designer requires this method. Do not modify
   		/// the contents of this method by using the code editor.
   		/// </summary>
   		private void InitializeComponent()
   		{
   			this.button1 = new System.Windows.Forms.Button();
   			this.SuspendLayout();
   			// 
   			// button1
   			// 
   			this.button1.Location = new System.Drawing.Point(64, 104);
   			this.button1.Name = "button1";
   			this.button1.Size = new System.Drawing.Size(160, 40);
   			this.button1.TabIndex = 0;
   			this.button1.Text = "button1";
   			this.button1.Click += new System.EventHandler(this.button1_Click);
   			// 
   			// Form1
   			// 
   			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
   			this.ClientSize = new System.Drawing.Size(292, 266);
   			this.Controls.Add(this.button1);
   			this.Name = "Form1";
   			this.Text = "Form1";
   			this.ResumeLayout(false);
   
   		}
   		#endregion
   
   		/// <summary>
   		/// The main entry point for the application.
   		/// </summary>
   		[STAThread]
   		static void Main() 
   		{
   			try
   			{
   				Application.Run(new Form1());
   			}
   			catch(Exception ex)
   			{
   				MessageBox.Show(ex.Message);
   			}
   			}
   
   
   		private void button1_Click(object sender, System.EventArgs e)
   		{
   			try
   			{
   				Form2 frm = new Form2();
   				frm.Show();
   			}
   			catch (System.Exception exc)
   				  {
   				MessageBox.Show("Handling the following exception: \n \n" +   exc.Message);
   				  }
   		}
   	}
   }
   

6. In Solution Explorer, right-click the project, point to Add, and then click Add New Item. The Add New Item dialog box appears.
7. Under Templates, click Windows Form. By default, a form that is named Form2 is created.
8. In the Form2 form, replace the existing code with the following code.

   using System;
   using System.Drawing;
   using System.Collections;
   using System.ComponentModel;
   using System.Windows.Forms;

   	/// </summary>
   	public class Form2 : System.Windows.Forms.Form
   	{
   		/// <summary>

   		/// </summary>
   		private System.ComponentModel.Container components = null;
   
   		public Form2()
   		{
   			//
   			// Windows Form Designer requires this method.
   			//
   			InitializeComponent();
   
   			//
   			// TODO: Add any constructor code after InitializeComponent call.
   			//
   		}
   
   		/// <summary>
   		/// Clean up any resources that are being used.
   		/// </summary>
   		protected override void Dispose( bool disposing )
   		{
   			if( disposing )
   			{
   				if(components != null)
   				{
   					components.Dispose();
   				}
   			}
   			base.Dispose( disposing );
   		}
   
   		#region Windows Form Designer generated code
   		/// <summary>
   		/// Windows Form Designer requires this method. Do not modify
   		/// the contents of this method by using the code editor.

   		private void InitializeComponent()
   		{
   			// 
   			// Form2
   			// 
   			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
   			this.ClientSize = new System.Drawing.Size(292, 266);
   			this.Name = "Form2";
   			this.Text = "Form2";
   			this.Load += new System.EventHandler(this.Form2_Load);
   
   		}
   		#endregion
   
   		private void Form2_Load(object sender, System.EventArgs e)
   		{
   
   				throw new System.Exception("My Exception");
   
   		}
   	}
   }

9. On the Build menu, click Build Solution. Then, press CTRL+F5 to run the application without using the debugger.
