Specifies the path for the output directory.
If not specified, it defaults to [project_file_folder]./bin/[configuration]/[framework]/publish/ for a runtime-dependent executable and cross-platform binaries. It defaults to [project_file_folder]/bin/[configuration]/[framework]/[runtime]/publish/ for a self-contained executable.
In a web project, if the output folder is in the project folder, successive dotnet publish commands result in nested output folders. For example, if the project folder is myproject, and the publish output folder is myproject/publish, and you run dotnet publish twice, the second run puts content files such as .config and .json files in myproject/publish/publish. To avoid nesting publish folders, specify a publish folder that is not directly under the project folder, or exclude the publish folder from the project.
Some behaviour depends on the SDK version:
