Visual studio 2015, C# STAThread not working

Question

STAThread在VS 2015中被忽略？我有我的主要方法：

[STAThread]
static void Main(string[] args)
{...}

我有一个使用System.Windows.Forms.OpenFileDialog的函数，它给了我以下异常：

｛"在进行OLE调用之前，必须将当前线程设置为单线程单元(STA(模式。请确保Main函数上标记了STAThreadAttribute。只有当调试器附加到进程时才会引发此异常

代码：

try
{
System.Windows.Forms.OpenFileDialog openFileDialog1 = new System.Windows.Forms.OpenFileDialog
{
InitialDirectory = @"C:",
Title = "Browse Text Files",
CheckFileExists = true,
CheckPathExists = true,
DefaultExt = "txt",
Filter = "txt files (*.txt)|*.txt",
FilterIndex = 2,
RestoreDirectory = true,
ReadOnlyChecked = true,
ShowReadOnly = true
};
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
}
}catch(Exception e)
{
}
