ConcurrentQueue and Parallel activity

Learn Academy Feedback

Hello, i have a xaml, and it’s works not as I expect.
I have a ConcurrentQueue with ten elements,
and parallel activity with two loops inside.
First problem: Only the first loop is always executed.
Second problem: To get the value from the queue I use myConcurrentQueue.TryDequeue(someString1)
I expect the value from the queue to be assigned to someString1, but it just delete value from the queue and doesn’t assign value to my variable.

Where are my mistakes?
Thank you.
