Application Windows Forms, Visual Studio 2012

I have a problem with Visual Studio 2012. I have this message "The designer could not be shown for this file because none of the classes within it can be designed" after the next actions: file - create - project - Application Windows Forms. I do not do nothing else. I have already tried to repair VS, but it couldn't help. Please, tell me what should I do to solve this problem. There is a code below:

Program.cs:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Windows.Forms;

    namespace WindowsFormsApplication9
    {
       static class Program
       {
          /// <summary>
          /// Главная точка входа для приложения.
          /// </summary>
          [STAThread]
          static void Main()
          {
             Application.EnableVisualStyles();
             Application.SetCompatibleTextRenderingDefault(false);
             Application.Run(new Form1());
          }
       }
    }

Form1.cs:

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;

    namespace WindowsFormsApplication9
    {
       public partial class Form1: Form
       {
          public Form1()
          {
             InitializeComponent();
          }
       }
    }

It seems like your Visual Studio installation is corrupt. The first answer to this question may solve your issue.

The solution is, briefly:

  1. Delete a value corresponding to the “Microsoft.VisualStudio.CSharp.Services.Language.Interop” assembly from the HKLM\SOFTWARE\Classes\Installer\Assemblies\Global\. Note the Interop part because there is also Microsoft.VisualStudio.CSharp.Services.Language assembly, which must be in the GAC.
  2. Start VS2012 x86 Native Tools Command Prompt and run gacutil /u Microsoft.VisualStudio.CSharp.Services.Language.Interop

Right click on project and go to Properties, make sure target framework is set to .NET 4.0 and not .NET 4.0 Client Profile or any other framework.
