Hello,

According to the msdn site .NET version 4 is downward compatable to 2.0. Are there any caveats to that, or the version 4 installation?

I need to compile an application to .NET 4, and copy it to a system with applications that use lower versions.

Thanks much.

You have a misunderstanding here. .NET 4.0 being backward or downward compatpible to .NET 2.0 means you will be able to run programs or use libraries that were created with an older version of .NET from 2.0 upwards on the .NET 4.0 framework.
The other way round can't possibly work. A program or a library that were compiled with .NET 4.0 will never work with older .NET versions.

Sorry! I don't understand what you are trying to say. If your original question wasn't phrased correctly then do so.
"I will still have .NET modules whose .NET versions are smaller than 4.0" OK so far there is nothing wrong with that!
".. my changes will be the only .NET 4 module " Now this is complete gibberish and needs to be formulated in something more closely related to English.

Regards,

Manfred

Did you try to say this:

" ... my changes will be only in the .NET 4 module ... " ?
