Visual Studio

• There may be minor issues when connecting to HoloLens using the VS Update 1. But these minor issues were fixed in Update 2, and we recommend that you use Visual Studio Update 2.

• HoloLens devices after you update the latest system, you may not be able to use the Visual Studio profiling Tools and graphical debugging tools. This will affect all devices that have developer mode enabled before updating the system. When you start the VS debugging tool, you may see an error message reminding you to restart your device. However, this is not an egg, and restarting will not work.

  • Workaround: After the device is updated, reset the device. After reconfiguring the developer mode, you may also receive an error message to remind you to restart your device. But this time, the problem will be fixed after restarting the device.
