Re: [aus-dotnet] Determining ANY Framework presence

[Alex Hoffman]

Check for two registry settings for 1.0 and 1.1 respectively:-

Software\\Microsoft\\.NETFramework\\Policy\\v1.0
Software\\Microsoft\\NET Framework Setup\\NDP\\v1.1.4322

If you want a small unmanaged application which reports these to the
command line (or silently for use in a batch file) - let me know.

Depends what you mean by "writing something in .NET".

You cannot run managed code without a version of .NET being installed.
That said, there is at least one 3rd party product that statically binds
parts of the Framework to an application, allowing no framework to be
present.

On the other hand, you can write an unmanaged application which itself
hosts an instance of the CLR, subject to the existence of an installed
framework.
