Alert windows xp

when I open sambapos v4 on XP I get this warning

The calling thread must be STA, because many UI components require this.

I forgot … I’m utilizzanjdo a virtual machine with virtualbox xp

reinstall .net

@spanky unfortunately we decided stop supporting XP for SambaPOS4. That prevents us from using .net framework 4.5 features because 4.5 does not work on XP.

thats too bad because i think lots of machines still working with XP like mine, i have IBM surepos500 that originally came with “XP embeded” and i donk know yet if i can upgrade to later windows versions

On April 8, 2014, support and updates for Windows XP will no longer be available from Microsoft.

but still, is sambapos can live a bit longer with net 4.0 instead of 4.5?

Yes this is a tough decision and I’ll be happy to support XP as well but now or 3 months later we have to drop XP support. For win8 mobile apps, new threading features or to be able to use upcoming features we’ll need to use new frameworks. There are problems that needs to be debugged on XP but I can’t even install current visual studio on XP :(

The problem with XP is that there has been no new .NET updates for XP for the last 2 years. There has only been security updates.

Right now SambaPOS is at a major milestone. For SambaPOS to move forward .NET 4.0 dependency has to be dropped.

i read in this link that it does support XP

But it’s .NET Framework 4.5 that is not supported in WinXP.
The issue isn’t VS.
