However, many times the app only requires a small subset of the framework to function, and other unused libraries could be removed. NET to be installed on the host computer. Self-contained apps include everything needed to run your code, without requiring. NET core 3.0 SDK comes with a tool that can reduce the size of apps by analyzing IL and trimming unused assemblies. or- dotnet publish -r win10-圆4 -p:PublishSingleFile=trueįor more information about single-file publishing, see the single-file bundler design document. To publish a single-file executable, set the PublishSingleFile in your project or on the command line with the dotnet publish command: The application doesn't need to extract itself a second time unless a new version was used. Startup is faster when the application is run again. When the app is first run, the application is extracted to a directory based on the app name and build identifier. The executable is self-extracting and contains all dependencies (including native) that are required to run your app. The dotnet publish command supports packaging your app into a platform-specific single-file executable. You can either configure the appHost at the project level, or toggle the appHost for a specific dotnet command with the -p:UseAppHost parameter:Ĭommand-line parameter dotnet run -p:UseAppHost=trueįor more information about the UseAppHost setting, see MSBuild properties for. An appHost is always created when you publish your app self-contained. Without the appHost, the only way a user can start a framework-dependent app is with the dotnet command.

Your app runs in the context of the appHost when it is run from source code with the dotnet run command, or by starting the Mach-O executable directly. NET Core generates a native Mach-O executable when you build or publish.
For more information, see macOS Catalina Notarization and the impact on. NET Core SDK 3.0 for macOS, the setting to produce a default executable (known as the appHost) is disabled by default. You can launch the application from a command prompt directly, such as myapp.exe on Windows, and.You can double-click on the executable.You can expect the same things with these executables as you would other native executables, such as: Previously, only self-contained deployments would produce an executable.ĭuring dotnet build or dotnet publish, an executable (known as the appHost) is created that matches the environment and platform of the SDK you're using. This behavior is new for applications that use a globally installed version of. NET Core now builds framework-dependent executables by default. If you're using Visual Studio, you need Visual Studio 2019, as Visual Studio 2017 doesn't support. NET Standard 2.1, edit your project file and change the TargetFramework property to netstandard2.1: However, the default dotnet new classlib template generates a project that still targets. Language enhancements were added to support the following API features detailed below: Tutorial: Use pattern matching to build type-driven and data-driven algorithms.Tutorial: Generate and consume async streams using C# 8.0 and.Tutorial: Express your design intent more clearly with nullable and non-nullable reference types.Tutorials related to C# 8.0 language features: For more information about C# 8.0 features, see What's new in C# 8.0.
