用VS2010创建了一个最简单的窗口程序(.net 4.0)，但是只有包含了Microsoft.DirectX.Direct3D的代码，程序运行到那里就假死，调试时连函数都不能跟进去。
解决方法是修改app.config文件添加如下节点配置
<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>
