I currently uses 3.5 sp1 with vst 2008, no plan to go to 2010 for at least
half a year.

However, someone wanted a dump of the crash visual studio 2008 standard and
I was not able to get the info they wanted. They suggest if I have dotnet 4
installed I can use another tool to make easier to get the dump they want

Should I install .net 4 or that will give me a lot of trouble?

3.5 and 4.0 can coexist.

It obviously require a bit of attention to ensure that
stuff that must be build on 3.5 indeed get build on 3.5
and not 4.0

No. Visual Studio 2008 will not build with anything higher than 3.5.

Microsoft has always forced people to upgrade Visual Studio with every major
release of the framework.

so visual studio 2008 would then default to build with 4.0 then?

No.

But you will have a 4.0 compiler, libraries and runtime on the
system.

And if you install 4.0 with VS 2010 then you will have a VS
that default build with 4.0.

Don't startup VS 2010 if installed, don't do any msbuild or
nant command line builds without checking what version is
being used.

Avoid third party stuff that relies on 4.0, because now
it will run on your development box, but not on the 3.5
systems you test and run production on.
