title: How to reset cache in project Visual Studio(winform)?
body: <p>Very weird things happens in my project Visual Studio.</p>
  
  <p>On the main Form I have three radiobuttons. One of them is selected. It is first radiobutton with property: <code>checked:true</code>. It has name <code>radioButton8</code>.</p>
  
  <p>When I start project I see that selected the second radio button with name <code>radioButton1</code>.</p>
  
  <p>I tried to find this element in project by its namw <code>radioButton1</code> in main Form. But there is not nothing, that can set this in checked state.</p>
  
  <p>What does happend with VS? How to clear project fully and reset cache?</p>
  
  <p>Also sometimes toolbox becomes to empty.</p>
  
  <p>I did searhing in current project and have found only this in <code>Main.Designer</code>:</p>
  
  <pre><code>   // radioButton1
              // 
              this.radioButton1.AutoSize = true;
              this.radioButton1.Location = new System.Drawing.Point(23, 58);
              this.radioButton1.Name = "radioButton1";
              this.radioButton1.Size = new System.Drawing.Size(90, 17);
              this.radioButton1.TabIndex = 4;
              this.radioButton1.TabStop = true;
              this.radioButton1.Text = "Прошли тест";
              this.radioButton1.UseVisualStyleBackColor = true;
              this.radioButton1.Click += new System.EventHandler(this.radioButton1_Click);
              // 
  </code></pre>
