VS2019 LINK Error 无法找到 mscoree.lib

偏执的太偏执、 2022-11-30 15:48 199阅读 0赞

从网上找到一个vs2015的项目，升级到vs2019编译，报错说找不到mscore.lib，在系统里找了一圈，发现确实没有这个文件。上网一搜，几乎都没哪个能清楚说明这个文件到底在哪里。

正确答案：

在.NET framework 的SDK里面，如下图所示，是在.NET Framework 4.6.1 SDK中，不是那个.NET Framework 4.6目标包。实际 上，应该是任何一个framework的SDK包都可以。我试了一下，安装完后立刻就可以编译了。

如果不想安装SDK，就下载这个到项目里直接编译就好了，如下

下面是网上给出的一个参考，这里还设置了环境变量（一般不需要，SDK会自己设置这些参数）

### \[vc141\] LNK1104: cannot open file 'MSCOREE.lib ###

### Summary ###

Cannot build C++/CLI project. Linker returns

LINK : fatal error LNK1104: cannot open file 'MSCOREE.lib'

### Investigation ###

`MSCOREE.lib` on my laptop is located in “C:\\Program Files (x86)\\Windows Kits\\NETFXSDK\\4.8\\Lib\\um\\x64” folder.

In the “Configuration Properties -> VC++ Directories” the value of “Library Directories” is

$(VC_LibraryPath_x64)
    $(WindowsSDK_LibraryPath_x64)
    $(NETFXKitsDir)Lib\um\x64

Which is after parameters are applied equals to

C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Tools\MSVC\14.16.27023\lib\x64
    C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Tools\MSVC\14.16.27023\atlmfc\lib\x64
    C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\VS\lib\x64
    C:\Program Files (x86)\Windows Kits\10\lib\10.0.16299.0\ucrt\x64
    C:\Program Files (x86)\Windows Kits\10\lib\10.0.16299.0\um\x64
    lib\um\x64
    Lib\um\x64

See last two lines at bottom. Those are values of `$(NETFXKitsDir)Lib\um\x64`.

So, for some reason for the toolset “vc141” the value of NETFXKitsDir is not defined. If I create `NETFXKitsDir` environment variable equal to `C:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\`, then I can build the project.

### Environment: ###

*  Visual Studio 2019
 *  Toolset: vc141
 *  Project’s Target Framework Version: 4.7.2
