DeviceContext.Release sometimes crashes.

[Gavin-Williams]

I have this in my device dispose method..

        DxDeviceContext.ClearState();
        DxDeviceContext.Flush();
        DxDeviceContext.Release();
        DxDeviceContext.Dispose();
        DxDeviceContext = null;

But the call to release will crash if the app is allowed to run through without doing anything - in the case where I haven't created a window for instance.

T: 1 | Application | Shutting down...
D3D11: DeviceChild reference counter underflow.  Release should not be called on objects with zero reference count.
Exception thrown at 0x00007FFEA83E474C (KernelBase.dll) in DemoBasics.exe: 0x0000087D (parameters: 0x0000000000000000, 0x0000003372BFCD30, 0x0000003372BFCD50).
Exception thrown: 'System.Runtime.InteropServices.SEHException' in SharpGen.Runtime.dll
An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in SharpGen.Runtime.dll
External component has thrown an exception.

If I comment out the call to release, the program closes down cleanly.

Am I meant to be doing some check here for existing references before calling Release?

You don't have to call both Release and Dispose, as Dispose calls Release behind the scenes
