"Another application has exclusive access to the device" error when you claim multiple devices through POS for .NET 1.14

View products that this article applies to.

Symptoms

When one or more applications that use the Microsoft Point of Service (POS) for .NET 1.14 try to claim more than one device, you receive the following exception:
POSControlException ErrorCode(Timeout) ExtendedErrorCode(0) occurred: Another application has exclusive access to the device and did not relinquish control before timeout milliseconds expired.

↑ Back to the top

Cause

This issue occurs because a .NET assembly calls an incorrect event API. It causes a single event to be created instead of creating multiple differently named events. Therefore, only one POS application can be claimed at a time.
