toady (Aug 20,2024) I updated my Visual Studio 2022 both stable and preview versions 17.11.0 and 17.12.0 Preview 1 respectively by running the Visual Studio Installer and choosing both to be updated. After the update, I created a new Blazor Web app with .NET 9 latest preview in my VS 2022 Preview and without making any modifications at all to the project, I simply clicked the debug button. I could see the IDE building the solution and starting the debug process, my Chrome browser started up but with a blank page and simply hangs there for ever. I had to stop the process, close Visual studio and restarted it. When I run the same project without debugging, it runs fine. I also tried with my Visual Studio 2022 Community Version 17.11.0 (stable). Though it was slow to start the Blazor app in debug mode, it did eventually started. It does not have a problem running it in non-debug mode either. What gives? Any idea anyone? This never happened to me before.
I am running Windows 11 with all updates. My machine has 64gb RAM, 2TB NVMe storage and a Ryzen 7 processor.
