VS2019 LINK Error 无法找到 mscoree.lib

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）

Cannot build C++/CLI project. Linker returns

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

MSCOREE.lib on my laptop is located in “C:Program Files (x86)Windows KitsNETFXSDK4.8Libumx64” folder.

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

$(VC_LibraryPath_x64)
$(WindowsSDK_LibraryPath_x64)
$(NETFXKitsDir)Libumx64

Which is after parameters are applied equals to

C:Program Files (x86)Microsoft Visual Studio2019ProfessionalVCToolsMSVC14.16.27023libx64
C:Program Files (x86)Microsoft Visual Studio2019ProfessionalVCToolsMSVC14.16.27023atlmfclibx64
C:Program Files (x86)Microsoft Visual Studio2019ProfessionalVCAuxiliaryVSlibx64
C:Program Files (x86)Windows Kits10lib10.0.16299.0ucrtx64
C:Program Files (x86)Windows Kits10lib10.0.16299.0umx64
libumx64
Libumx64

See last two lines at bottom. Those are values of $(NETFXKitsDir)Libumx64.

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 KitsNETFXSDK4.8, then I can build the project.
