Cannot start debugger for NET Framework App on Visual Studio 2022 Arm64

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:

1. Microsoft Visual Studio Community 2022 (ARM 64-bit) - Preview Version 17.13.0 Preview 3.0, Windows 11 Arm64
2. Create a new Windows Form App (NET Framework 4.8)
3. Cannot start debugger - nothing happens after clicking the "Start" button
4. 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.

 

Is there any one who has similar issues?

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.

 

Dear Parallels Support Team,

I am planning to use Visual Studio 2022 via Parallels on a MacBook with the following specifications:

• Apple M4 chip
  
  
• 6-core CPU
  
  
• 40-core GPU
  
  
• 128 GB unified memory
  
  
• 1 TB SSD storage
  

I develop Windows desktop applications using .NET Framework 4.6 and need to work with multiple existing projects. In the past, I used an Intel-based MacBook with Parallels without any major issues.

Before purchasing the new M4-based MacBook, I would like to confirm:

1. Can I expect comparable performance to a native Windows PC for development tasks?
   
   
2. Are there any known compatibility or performance issues when using Visual Studio 2022 and .NET Framework 4.6 with Parallels on Apple Silicon, especially M4?
   
   
3. Is there full support for Windows desktop development workflows in this setup?
   

I would appreciate your feedback or any recommendations regarding this configuration.

Best regards,
