Why is my C++ build slower under MSBuild 3.5?

Question

Hi

I am evaluating the upgrade from Visual Studio 2005 to Visual C++ 2008 Express and am specifically looking at the build time from the command line using MSBuild for a solution created with VS2005.

I notice that Visual Studio 2005 uses MSBuild 2.0 while VC2008 uses MSBuild 3.5.

Both invoke .NET 2.0 for my sln. I assume that this is because VS2008 imported the .sln file and forced the TargetFrameworkVersion to 2.0. Am I correct?

I find that the MSBuild 3.5 build time is 36% longer than the MSBuild 2.0 build time and the resulting .exe is 22% larger.

Please can anyone explain why the build time is significantly longer with 3.5?

Best regards

David

Hi Mike,

I did see that thread but, to be honest, I didn't understand the conclusion. I would prefer to avoid precompiled headers. Are they saying that I should rearrange the search paths?
