Question

I recently updated Visual Studio 2010 to SP1 and noticed the .NET 4 framework changed from version “4.0.30319.1” to “4.0.30319.225”. I was not able to locate an updated .NET 4 framework installer for “4.0.30319.225”. I could only find an update exe which is used to update a particular machine. When I deploy my application now, it still uses the older pre-SP1 version of the framework.

Is there a new bootstrapper that I should be using? Are there any issues with deploying an application that is developed/tested on “4.0.30319.225” to a target machine which only has “4.0.30319.1” ?

According to a comment on Announcing Visual Studio 2010 Service Pack 1 (check page two of the comments) from Jason Zander:

There have been questions about
updates to the .NET Framework. There
is no full service pack for .NET
Framework 4. However there is an
update which you can download from
here: go.microsoft.com/fwlink. The
outline of fixes (linked from the
download page) is here:
support.microsoft.com/…/2468871.

This update is titled “Microsoft .NET
Framework 4 KB2468871”. You can read
more about what is in the update on
the download page.

As I mentioned in a previous comment,
VS2010 SP1 requires this update and
will automatically install it as part
of setup.

When you build a project using VS2010
SP1, it does not force a dependency on
the update. Whether you need to
deploy the update with your client or
server application depends on your
need for the fixes in the update. You
will need to look through what it
contains to make that call.

I’ve personally seen no issue publishing to a server before running the update manually.

I can’t speak to the bootstrapper question.
