Microsoft .NET

[Lawson]

Is it necessary to have Microsoft .NET framwork 1.1, 2.0, and 3.0? It seems
a little redundant to me. Can the older versions be removed safely without
any performance issues? Just wondering.

No it doesn't work that way.

If you have an application that uses/needs .NET 1.1 then 2.0 and 3.0 are not
to be considered supersets of 1.x
So if you where to delete 1.1 then there is a good chance the application
will fail.

Each version of .NET is usually installed along with the application that
requires it, so if you have all three versions then chances are that
somewhere along the way you installed at a minimum 3 applications, with each
of those 3 applications requiring it's own version of .NET

No. Some programs requiring the .net framework require specific
versions. It's best to keep them all. Besides, they use a tiny amount
of disk space.

Not only must you keep the versions you mentioned, for the reasons given
above, you seem to be missing .NET Framework 3.5 - so go get it.
