为什么在任何.csproj文件中找不到<Target Name =“Build”>？

Question

Just curious - whenever I see xml of .csproj , it starts with DefaultTargets="Build" and hence I assume that <Target Name="Build"> should be present; However, I have never found this default target in any .csproj file.

Does VS inject this target before compilation or does msbuild built it by default. What happens internally?

Answer 1

Near the bottom of the file you'll see this; <Import Project="$(MSBuildToolsPath)\\Microsoft.CSharp.targets" /> which imports the standard targets, "Build" is one of these. The import generates the "Build" target in a dynamic fashion based on the other data available in the your project file.

Answer 2

A csproj typically has this:

  <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />

which according to MSDN also imports Microsoft.Common.targets which is where that target is defined.

Answer 3

项目文件中有一个或多个<Import ...>导入应该具有该目标的其他文件...
