Correct me if I’m wrong – I understand a C#/.NET application’s .csproj project file is effectively its makefile or build file.
A Website project does not have a .csproj file (not to be mixed up with Web Application which does). In the case of a Website project, can I create a makefile equivalent, or does it use a build process/instructions stored elsewhere in the system or app?
.csproj file mainly contains metadata information related your Environment your resource refrence, and MSBuild target to compile the specific project type,
You can Customize your website output by going to project property -> MSBuild Output section.
