I've just finished switching over our development environment from
Visual Studio 2005 to Visual Studio 2008 (except for a C++ solution that
uses boost, which will take some further effort). These are the things
that I needed to do, and the gotchas I encountered.
- Getting installed - Aside from being a lengthy experience,
installing VS 2008 went pretty smoothly on our machines except for
my own primary development box. The Web Authoring Component
didn't install. There is a long discussion
people with the same problem, apparently caused by having
pre-release versions of Microsoft software. In my case, I had a
prerelease version of Expression Web on my machine, and uninstalling
that allowed the VS 2008 install to complete normally.
- Converting solutions -When you open a VS 2005 solution in VS
2008, the Conversion Wizard shows up automatically. It seemed like
this was going to be an easy part, but none of the unit test
projects converted correctly. This is apparently a bug, and a
byzantine workaround is
on the MSDN Forums. Fortunately, John Carneiro posted a tool that
automatically applies the workaround (in the same forum thread as
- Fixing unit test framework references - Part of our build
process uses MSTest.exe to run our unit tests. When I first tried
this, I got this error message: "The test DLL 'Common.Tests.dll' was
built using Visual Studio 2005, and cannot be run. To resolve this
issue please rebuild the test DLL using the current version of
Visual Studio". Since I had just rebuilt everything with VS 2008,
this was somewhat puzzling. Eventually I figured out that by
"...built using Visual Studio 2005...", the error message was really
trying to say "...built referencing the Visual Studio 2005 version
of the unit test framework...". While the instructions for upgrading
the unit test projects said to fix references to
Microsoft.VisualStudio.QualityTools.UnitTestFramework to reference
version 126.96.36.199 instead of 188.8.131.52, John's tool apparently didn't do
that for me.
- Finding a new strategy for Sgen - I've written about generating
the past, and how I came up with a command line to use as a
post-build step. I discovered, however, that sgen.exe is not in the
same place in the VS 2008 install. This led me to a better solution
anyway of using the Sgen MSBuild
instead, as suggested
- Removing the /Wp64 switch - Some of my projects are C++/CLI, and
had the /Wp64 switch on. This produces a warning now: "Command line
warning D9035 : option 'Wp64' has been deprecated and will be
removed in a future release". I guess the reason for deprecating the
option is that if you want to check for 64 bit compatability issues,
you can just run the 64 bit compiler, according to this
I just turned off the "Detect 64-bit Portability Issues" in
the project C++ options.
There were also some miscellaneous things that are less applicable to
other development teams:
- We have an Ant task that builds Visual Studio solutions by invoking
DEVENV.COM, and that needed to be updated to correlate the version
10 solution file format with the appropriate path to DEVENV.COM.
- We have a test runner application (a thin wrapper over MSTest.exe)
that needed to be updated a little.
- We use TeamCity for continuous builds, and that needed some
attention as well (still working on those details).
