CSharpSyntaxValidator is a .NET Core CLI tool that validates a C# source for syntax errors and sets its exit code to zero (0) if the C# source is valid and one (1) if invalid.
It is not a linter for C#.
You will need .NET Core SDK 2.2 or later installed.
Install CSharpSyntaxValidator as follows:
dotnet tool install --global CSharpSyntaxValidator
Simply invoke supplying C# source on standard input:
csval < Program.cs && echo OK
If the source is valid, the above will print OK on your terminal.
Alternatively, supply the file name directly:
csval Program.cs && echo OK
For more help on usage, run with the -h option:
csval -h
The .NET Core SDK is the minimum requirement.
