majiayu000 dotnet run app.cs
Run C# files directly without .csproj project files. Requires .NET 10 (SpeedReader uses .NET 10, so this should already be installed).
dotnet run hello.cs
Usage Examples
#!/usr/bin/env dotnet run // shebang (unix)
#:sdk Microsoft.NET.Sdk // sdk (default; also .Web, .Worker)
#:package Humanizer@2.14.1 // nuget package (version required, wildcards ok)
#:property LangVersion=preview // msbuild property
#:project ../src/MyLibrary // project reference
Console.WriteLine("Hello, World!");
dotnet run hello.cs # run
dotnet run hello.cs -- arg1 arg2 # run with args
chmod +x hello.cs && ./hello.cs # run via shebang
cat hello.cs | dotnet run - # run from stdin
dotnet publish hello.cs -c Release # publish
dotnet project convert hello.cs # convert to full project w/ csproj
Shared Configuration
Share settings across multiple single-file apps by placing a Directory.Build.props file in the same or parent directory:
<Project>
<PropertyGroup>
<LangVersion>preview</LangVersion>
<TreatWarningsAsErrors>true</TreatWarningsAsErrors>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
</ItemGroup>
</Project>
All .cs files in that directory tree inherit these settings.
