VS2019 C#与VS2017 C++项目：如何生成无需C++ Redistributable的.exe？

Hey there, let's solve this DLL missing issue without having to add a full installer—here's how to configure both your projects to cut that redist dependency:

For Your VS2017 Community C++ Executable #

This is where the majority of your redist dependency comes from, so we'll focus here first:

• Static-link the C++ Runtime Library
  Open your C++ project properties, then navigate to:
  Configuration Properties > C/C++ > Code Generation > Runtime Library
  For Release builds, select Multi-threaded (/MT); for Debug builds, select Multi-threaded Debug (/MTd). This embeds the necessary C++ runtime components directly into your .exe, so it won't rely on the separate redistributable package.

• Check for Other Dependencies
  Use a tool like Dependency Walker or Visual Studio's built-in dumpbin command to verify no other external DLLs are required:

  dumpbin /dependents YourCppExe.exe
  

  Ignore system DLLs (like kernel32.dll or user32.dll—these come with Windows), but if you're using any third-party libraries, make sure those are also statically linked or include their DLLs alongside your executable.

• Adjust MFC/ATL Settings (if applicable)
  If your C++ project uses MFC or ATL, go to Configuration Properties > General > Use of MFC and select Use MFC in a Static Library to avoid additional runtime dependencies.

For Your VS2019 Community C# UI Project #

While C# typically has lighter dependencies, you can ensure smooth deployment too:

• Use Self-Contained Deployment (for .NET Core/.NET 5+)
  If you're targeting .NET Core, .NET 5, or later:

  1. Right-click your C# project > Publish
  2. Choose Folder as the target
  3. In publish settings, set Deployment Mode to Self-contained
  4. Pick the appropriate Target Runtime (e.g., win-x64 for 64-bit Windows)
     This packages the entire .NET runtime with your app, so target machines don't need pre-installed .NET.

• Include the C++ Executable in Your Deployment
  Make sure to copy your compiled C++ .exe (and any remaining necessary DLLs, if any) into your C# project's output directory, or add them as "Content" files in the C# project so they get included during publish.

Final Verification #

Test your deployed app on a clean machine (one without Visual Studio or the C++ 2015 Redist installed) to confirm no DLL errors pop up. If you still run into issues, recheck your C++ project's runtime library setting—this is the most common fix for redist dependency problems.
