Are we talking web applicatoins or exe apps ?

For a web applicatoin you configure the individual appliacation in IIS to target a particular version of the framework.

Generally it is also advisable to create multiple application pools in IIS one for each of the versions you will be using.
Web apps for different version of .net should not share the same application pool.

For an exe or other assembly you can check at runtime in your code which version the current assemhbly is running in.

How do I configure the individual appliacation in IIS to target a particular version of the framework?

I am using IIS 5

It should be this :

Right-click on the application directory or virtual directory in the IIS Admin tool and select Properties.
In  the properties dialog select the asp.net tab.
On the asp.net tab set the asp.net version in the version drop-down box.

But I don't have an IIS 5.0 server to check this on.

Also, learn about:   aspnet_regiis.exe
http://msdn2.microsoft.com/en-us/library/k6h9cz8h(vs.80).aspx

This is used in a command window.
Remember to always change directory to the proper directory (for ASP.NET 1.1 or 2.0)

for 1.1 (if installed in default location)
CD C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322

for 2.0 (if installed in default location)
CD C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

aspnet_regiis -lk
will list the applications and versions of ASP.NET they use.

Watch out for some of the options, as they may update ALL sites on your machine, which may not be what you want.
