为什么它对这个文件不起作用<Import />，当我用复制粘贴三个属性替换语句时它起作用？

../../Setup.Version.proj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
    </PropertyGroup>
</Project>

作品：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>

不起作用：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="../../Setup.Version.proj" />
    <PropertyGroup>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>

这里的变量只是评估为空字符串... :( 我确定导入项目的路径是正确的。

因此，当我从命令行运行 msbuild 时它似乎工作正常，但当我在 Visual Studio 中构建项目时却不行。为什么在世界上？

I've tried to reproduce and everything works:

importme.proj

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <InstallerMajorVersion>7</InstallerMajorVersion>
        <InstallerMinorVersion>7</InstallerMinorVersion>
        <InstallerBuildNumber>7</InstallerBuildNumber>
    </PropertyGroup>
</Project>

main.proj

<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="importme.proj" />
    <PropertyGroup>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>
    </PropertyGroup>
    <Target Name="Build">
        <Message Text="$(OutputName)"/>
    </Target>
</Project>

OUTPUT

UPDATE: You need to reload project for Include'd files to be updated or use workaround.

The reason it didn't work is that Visual Studio had cached the included file, so that any changes I made to it didn't take effect until I reloaded the solution or restarted Visual Studio. This seems to be a limitation of VS 2010. After reloading VS 2010, everything worked as expected.

Import元素仅在该元素下有效Project。但是，代码似乎想要将值导入到<ProjectGroup>元素中。尝试在 Setup.Version.proj 中将值声明为变量并在主 MSBuild 文件中引用它们，例如：

<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="../../Setup.Version.proj" /> <!-- Variables declared in here -->
    <PropertyGroup>
        <InstallerMajorVersion>$(MyInstallerMajorVersion)</InstallerMajorVersion>
        <InstallerMinorVersion>$(MyInstallerMinorVersion)</InstallerMinorVersion>
        <InstallerBuildNumber>$(MyInstallerBuildNumber)</InstallerBuildNumber>
        <OutputName>asdf-$(InstallerMajorVersion).$(InstallerMinorVersion).$(InstallerBuildNumber)</OutputName>
        <OutputType>Package</OutputType>
