c++ /CLI库将.netcore作为VS 2017 c++应用程序的依赖项

Question

我正在尝试从c++应用程序调用。net core函数。

为此，我有一个c++/CLI库，它将。net core库作为依赖项，然后从该库调用。net core函数。我把这个c++/CLI库作为一个c++应用程序的依赖项，然后运行这个c++应用程序。

c++/CLI library ->TestCPPCLI

。Netcore库->TestNetcoreDll

VS 2017 c++应用程序->Testcpp

当我尝试运行c++应用程序时，我得到错误Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'TestNetcoreDll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

在编译TestCPPCLI时，我得到这个链接器警告1>LINK : warning LNK4199: /DELAYLOAD:TestNetcoreDll.dll ignored; no imports found from CVMQClient.dll

在VS2017 c++应用程序中，我们可以依赖于针对。net core的c++/CLI库吗?

如何在vcxproj的c++/CLI应用程序中包含。net core库?

</ClCompile>

<Link>
<DelayLoadDLLs>TestNetcoreDll.dll;%(DelayLoadDLLs)</DelayLoadDLLs>
</Link>
</ItemDefinitionGroup>

在vcxproj中，我在AdditionalLibraryDirectories和AdditionalIncludeDirectories中也包含了库和头文件位置

不，你不能链接dll，你需要添加它作为引用。

<ItemGroup>
<Reference Include="TestNetcoreDll">
<HintPath>TestNetcoreDll.dll</HintPath>
</Reference>
</ItemGroup>
<!--ClCompile>
<ForcedUsingFiles>TestNetcoreDll.dll</ForcedUsingFiles>
</ClCompile>
<Link>
<DelayLoadDLLs>TestNetcoreDll.dll;%(DelayLoadDLLs)</DelayLoadDLLs>
</Link-->
