How to publish only required dependencies?

Question

If I create a "Hello World" .NET Core C# Console application in Visual Studio 2017 and run

dotnet publish -c Release -r win10-x64 --self-contained

The resulting publish folder has 215 files in it, totals 62MB and includes the whole of .NET, which the application doesn't use. For example, it has System.Security.Cryptography.OpenSsl.dll.

This is part of the "Microsoft.NETCore.App" dependency which I seem to have no way to edit manually. How can I trim that down to what the application is actually using?

Answer 1

根据deployment documentation：

  

与FDD不同，自包含部署（SCD）不依赖于目标系统上共享组件的存在。所有组件包括.NET Core库和.NET Core运行时都包含在应用程序中

     

（强调我的）

如果您不想将整个.NET Core运行时与应用程序一起部署，那么您应该使用Framework-dependent Deployment（FDD）而不是Self-contained Deployment（SCD）。

dotnet publish -c Release

将来，CoreRT runtime - 在编写时仍在开发中 - 旨在允许创建特定于运行时的单个预编译本机可执行文件，而不需要任何其他文件。

还有第三个选项：“ https://logging.apache.org/log4j/2.x/manual/configuration.html”

您需要使用--self-contained false，例如：

dotnet publish <xyz.csproj> -c Release -r win-x64 --self-contained false

“发布”文件夹仍然包含一些Microsoft。*。dll。但是方式更少。就我而言，以前的发布是文件夹大小为84MB，现在只有12MB​​！
