Why I am getting "LNK1104: cannot open file 'MSCOREE.lib'" error when building a C++/CLI program?

Visual C++ supports the C++/CLI (Common Language Infrastructure) programming language, which has additional types and operators to target the .NET programming model. It is done by using the CLR (Common Language Runtime) from the .NET Framework.

This tutorial shows you how to use a text editor to create a basic C++/CLI program, then compile and link it on the command line.

1. Enter the C++/CLI program, HelloCLI.cpp with a text editor:

// HelloCLI.cpp
// Copyright (c) FYIcenter.com

int main() {  
    System::Console::WriteLine("Hello World! - From C++/CLI.");  
} 

2. Run "All Programs > Visual Studio 2017 > Visual Studio Tools > Developer Command Prompt for VS 2017". You see the Visual Studio Command Prompt window.

3. Compile and link the C++/CLI program, HelloCLI.cpp, with the "/clr" (Common Language Runtime) option:

C:\fyicenter>cl /clr HelloCLI.cpp
Microsoft (R) C/C++ Optimizing Compiler Version 19.10.25019
for Microsoft (R) .NET Framework version 4.06.1055.0
Copyright (C) Microsoft Corporation.  All rights reserved.

HelloCLI.cpp
Microsoft (R) Incremental Linker Version 14.10.25019.0
Copyright (C) Microsoft Corporation.  All rights reserved.

/out:HelloCLI.exe
HelloCLI.obj
LINK : fatal error LNK1104: cannot open file 'MSCOREE.lib'

You are getting this error, because the C++/CLI Support component is missing Visual Studio. See the next tutorial on how to install it.
