VS2010 編譯的Direct3D程序不能運行解決方法

用VS2010創建了一個最簡單的窗口程序(.net 4.0)，但是隻有包含了Microsoft.DirectX.Direct3D的代碼，程序運行到那裏就假死，調試時連函數都不能跟進去。

解決方法是修改app.config文件添加如下節點配置

  <configSections>
    <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="OpenAWindow.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
    </sectionGroup>
  </configSections>
  <userSettings>
    <OpenAWindow.Properties.Settings>
      <setting name="formState" serializeAs="String">
        <value>Maximized</value>
      </setting>
    </OpenAWindow.Properties.Settings>
  </userSettings>
