Parallels Version 20.2.1 (55876). I originally thought this problem is related to VS 2022 and posted this issue on Visual Studio feedback (see https://developercommunity.visualst...or-NET-Framework/10843074?sort=newest&q=arm64). But the staff said they didn't have this problem on their Arm64 machine. Steps to reproduce: Microsoft Visual Studio Community 2022 (ARM 64-bit) - Preview Version 17.13.0 Preview 3.0, Windows 11 Arm64 Create a new Windows Form App (NET Framework 4.8) Cannot start debugger - nothing happens after clicking the "Start" button I also tested all these configurations: Any CPU, ARM64, x86, and x64. Only in x86 the debugger can start.
Also tested on Microsoft Visual Studio Community 2022 (ARM 64-bit) Current Version 17.13.0. Still not working.
[/QUOTE] Thanks for the detailed breakdown! This seems like a compatibility issue with .NET Framework debugging on ARM64 in Visual Studio 2022 Preview. Since only x86 works, it may point to limitations in debugger support for .NET Framework apps on ARM64. You might try running the app under Rosetta (via x86 emulation) or consider using .NET Core/.NET 6+ if feasible for better ARM64 support.
Microsoft engineer confirmed this problem does not occur on native arm64 machine. So this is related to Parallels only.
