so when it will work well?
Unfortunately, we don't have an ETA on when it can be fixed. This is mainly because ASP.NET is a Windows language and we run purely Linux servers. We use something called mod_mono to emulate the ASP.NET environment, but this doesn't always work very well with our configuration.
If you're looking to create ASP.NET webpages, you might be better off with a web host running Windows servers.
