找不到支持的蓝牙协议栈

Question

我在VS2017中使用Windows 7和C＃，.net4.6.1。我将蓝牙CSR 4.0加密狗和csr激素蓝牙堆栈用作第三方蓝牙驱动程序。

我按此编写了一个hcitool程序： Looking to write Bluetooth 'hcitool' equivelant in Windows

但是当我尝试运行程序以连接BLE设备时。该行发生错误
    var dev = new BluetoothDeviceInfo（_searchAddress）; 错误是：找不到支持的蓝牙协议堆栈。

我已经仔细检查过，并且我传递的参数正确（信息+设备地址）
