ASP.NET Core directory structure
By Luke Latham
The publish directory contains the app's deployable assets produced by the dotnet publish command. The directory contains:
- Application files
- Configuration files
- Static assets
- A runtime (self-contained deployment only)
|App Type||Directory Structure|
†Indicates a directory
The publish directory represents the content root path, also called the application base path, of the deployment. Whatever name is given to the publish directory of the deployed app on the server, its location serves as the server's physical path to the hosted app.
The wwwroot directory, if present, only contains static assets.
A Logs directory can be created for the deployment using one of the following two approaches:
Add the following
<Target>element to the project file:
<Target Name="CreateLogsFolder" AfterTargets="Publish"> <MakeDir Directories="$(PublishDir)Logs" Condition="!Exists('$(PublishDir)Logs')" /> <WriteLinesToFile File="$(PublishDir)Logs\.log" Lines="Generated file" Overwrite="True" Condition="!Exists('$(PublishDir)Logs\.log')" /> </Target>
<MakeDir>element creates an empty Logs folder in the published output. The element uses the
PublishDirproperty to determine the target location for creating the folder. Several deployment methods, such as Web Deploy, skip empty folders during deployment. The
<WriteLinesToFile>element generates a file in the Logs folder, which guarantees deployment of the folder to the server. Folder creation using this approach fails if the worker process doesn't have write access to the target folder.
Physically create the Logs directory on the server in the deployment.
The deployment directory requires Read/Execute permissions. The Logs directory requires Read/Write permissions. Additional directories where files are written require Read/Write permissions.
ASP.NET Core Module stdout logging doesn't require a Logs folder in the deployment. The module is capable of creating any folders in the
stdoutLogFile path when the log file is created. Creating a Logs folder is useful for ASP.NET Core Module enhanced debug logging. Folders in the path provided to the
<handlerSetting> value aren't created by the module automatically and should pre-exist in the deployment to allow the module to write the debug log.
