Using Parallels for Cross-Platform App Development & Testing - Best Tools, Tips?

Hi everyone,

I'm currently working on an app development project that needs to run smoothly across both Windows and macOS. To streamline testing and development, I've been using Parallels Desktop to run virtual environments on my Mac.

I wanted to ask the community:
Is Parallels your go-to for cross-platform app testing?
I've been testing both native and web apps--curious if anyone here has optimized their workflow with Parallels for speed and efficiency.
What tools do you recommend running inside the VM?
For example, I'm using Visual Studio on Windows and Xcode on macOS. Any tips on syncing codebases between guest and host OS?
How do you handle performance testing inside a VM?
Do you notice any major differences vs. real devices or dual-boot setups?

Also, if anyone here is into mobile app development or AI-based app development, I'd love to connect and hear how you're handling multi-OS testing, emulators, or automation within Parallels.
Looking forward to your insights!
