Hi, my name is Li Shao<\/strong>. I am a Software Design Engineer in Test in C++ team. In VS2010, C++ has accomplished the migration of VCBuild to MSBuild based project and Build system. We have received very warm acceptance and overall customer satisfaction is very good. You can take a look of a few of my previous blogs (Native MultiTargeting<\/a>, Conversion<\/a>, Custom Build Rules<\/a>) for some features and issues related to migration to MSBuild based build system for C++. VS2010 VS2010 SP1 release is around the corner. I would like to take this opportunity to let you know a few improvements that we have made in this area based on your feedback.<\/p>\n

 <\/p>\n

Managed Incremental Build<\/h4>\n

When referencing managed assemblies, a full rebuild is only needed when there are significant changes in the referenced assemblies. Significant<\/em> changes include things like assembly version change, function signature, interface changes, etc. This functionality will greatly reduce the build time for managed or managed\/native interop applications, where managed or managed assemblies are referenced.<\/p>\n

We first introduced the managed incremental build feature in VS2008. In VS2010, we were not able to re-implement the managed incremental build feature with the build system moving to MSBuild. We received strong customer requests for this feature. As a result, we re-implemented this feature and it is included in VS2010 SP1.<\/p>\n

\"Enable<\/a><\/p>\n

 <\/p>\n

Custom Dependency File List for Incremental Build<\/h4>\n

One of the customer reported issues is that for VS2010 disregards the \/\/{{NO_DEPENDENCIES}}<\/span> line in the resource.h<\/span> of MFC applications. When there is a resource.h<\/span> change either manually or by adding a resource ID using the resource editor, all the files that include resource.h<\/span> get rebuilt. This has a negative performance impact since resource.h<\/span> can be included by many files. It is also a behavior change from VS2008.<\/p>\n

To fix the problem, in VS2010 SP1, we have implemented a fix so that you can specify the list of header files that they would like to skip when doing incremental build. The property introduced is \u201cNoDependencies<\/span>\u201d. There are four ways that you can take advantage of this feature:<\/p>\n

1. Set as an environment variable<\/p>\n

You can use this approach if the dependencies to resource header files are common across all your projects. For example: set NoDependencies=resource.h;resource2.h<\/span>.<\/p>\n

You can set this in the environment that you launch Devenv or set this in your build environment<\/p>\n

2. Set through property sheet<\/p>\n

You can create a property sheet and set General -> No Dependencies File List<\/span> to the list of files that you would like to exclude from dependency check.<\/p>\n

\"No<\/a><\/p>\n

3. Set as a global property for your project<\/p>\n

You can set the property as the following to the \u201cGlobal<\/span>\u201d property of the project file:<\/p>\n

\n
\n
\n
    \n
  1. <<\/span>PropertyGroup<\/span> Label<\/span>=<\/span>“Globals<\/span>“><\/span><\/li>\n
  2. <<\/span>ProjectGuid<\/span>>{<\/span>3C2EE7D3-A2C9-40A5-91F0-3F988C8D5DF5}<\/<\/span>ProjectGuid<\/span>><\/span><\/li>\n
  3. <<\/span>Keyword<\/span>><\/span>AtlProj<\/<\/span>Keyword<\/span>><\/span><\/li>\n
  4. <<\/span>NoDependencies<\/span>><\/span> resource.h;resource2.h<\/<\/span>NoDependencies<\/span>><\/span><\/li>\n
  5. <\/<\/span>PropertyGroup<\/span>><\/span><\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n

    4. Set as a file level property<\/p>\n

    \n
    \n
    \n
      \n
    1. <<\/span>ClInclude<\/span> Include<\/span>=<\/span>“resource.h<\/span>“><\/span><\/li>\n
    2. <<\/span>NoDependency<\/span>><\/span>true<\/<\/span>NoDependency<\/span>><\/span><\/li>\n
    3. <\/<\/span>ClInclude<\/span>><\/span><\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n

      Note that this feature only works if you would like to skip certain headers from incremental building. It does not work for files other than header files.<\/p>\n

       <\/p>\n

      Signing of Managed Assemblies<\/h4>\n

      In VS2010, there was a bug that signing of the managed assemblies cannot be accomplished when Linker -> Advanced -> Delay Sign<\/span> is set to \u201cYes<\/span>\u201d. We have previously recommended a workaround to address this issue. In general, you would need to use post build steps to sign the assembly. This is a regression in terms of functionality from VS2008 behavior. In VS2010 SP1, we have attempted to fix the problem. However, there were still some issues with the fix. You can take a look of this blog<\/a> posted by my colleague Amit Mohindra on how to fix the problem. Essentially, you need to manually modify Microsoft.Cpp.Win32.targets<\/span>. You can also take a look of this readme (http:\/\/go.microsoft.com\/fwlink\/?LinkId=210711<\/a> \u2013 section 2.4.1.2) if you have application converted with VS2010 prior to SP1 RTM.<\/p>\n

       <\/p>\n

      These are the major changes we have made in SP1 regarding C++ build scenarios. Please let me know if you think there are issues we should have fixed. We will try to address them in future releases.<\/p>\n","protected":false},"excerpt":{"rendered":"
