An unhandled exception of type ‘System.InvalidOperationException’ occurred in Microsoft.SPOT.TinyCore.dll

I attached a picture which shows the error

The most common mistake is not having the latest firmware. Please make sure you have the latest SDK, see release notes. After installation, make sure you’ve loaded the latest firmware on the device. The firmware is updated though the integrated updater software found under the start menu. If that fails, or if your device doesn’t have such software, you can always run the update manually.

Hmm, quickreply needs an update. Look instead for latest documents and firmware stuff.

Furthermore. In case it does not help. Always provide details of your setup.
