Fabric Fabric Workload DevGateway/Backend Works Only Once After Restart — Then Stops Responding

[ameen_lumel]

I'm working with the Microsoft Fabric Workload Development Sample repo. I followed the official Fabric WDK quickstart and set up everything: frontend, backend, and DevGateway.

Problem:

• My backend runs successfully on http://localhost:5000 (or https://localhost:5001)

• The first API call works perfectly right after backend start (example: creating a workload item)

• But after the first request, any further request hangs and times out

• The DevGateway logs show it's forwarding correctly, but backend doesn't respond

• Also, PowerShell (running dotnet run) becomes unresponsive after backend starts
