The Microsoft .NET Framework is a development and execution environment that allows different programming languages & libraries to work together seamlessly to create Windows-based applications that are easier to build, manage, deploy, and integrate with other networked systems.
The Microsoft .NET Framework Software Development Kit (SDK) includes everything developers need to write, build, test, and deploy .NET Framework applications, documentation, samples, and command-line tools and compilers.
HOWTO
Each .NET Framework version has a separate HOWTO section. Please read it first before filing bugs or test reports!
/home/yourlogin/.wine is not owned by you / (Permission denied)
Never run wine as root (su, sudo)! Wine doesn't require to be run as root!
You will screw your WINEPREFIX and possibly other things up. If you have run Wine as root you need to:
$ sudo rm -rf ~/.wine
and then run winecfg to set Wine folder structure back up. If you used winetricks script as root you might also need to:
$ sudo rm -rf ~/.cache/winetricks/
Again: Just run wine as regular user and all should be fine.
