Windows on M1 Mac & Visual Studio

Hi!

My intel macbook broke and i was thinking to buy the new M1 Macbook. But i found out Boot Camp doesn't work anymore and most virtual machines don't either. Parallels seems to have an option to do this. But it is not clear wether:
1. you can download the installation windows image only from the insider program
2. windows has to be activated once installed otherwise it cannot be used. (on my old macbook I didn't activate windows but I could still use it)
3. every program works on the virtual machine just like a normal virtual machine / laptop.
4. it's actually legal to use win11 on m1 macs with parallels

I need to run Visual Studio to create Windows Forms Applications in C Sharp.. does this work on Parallels with M1 processor Macs?

This is kind of urgent...
Thank you in advance for any helpful answer.
