Overview

This action runs the .NET code quality ("CAxxxx") and code style analyzers("IDExxxx") that ship with the .NET SDK.

Inputs

Mandatory Inputs

Name	Description
build-breaking	Boolean value true or false indicating if code analysis violations should break the build.

Optional Inputs

AnalysisLevel values

The following table shows the available AnalysisLevel options.

Value	Meaning
latest	The latest code analyzers that have been released are used. This is the default.
preview	The latest code analyzers are used, even if they are in preview.
5.0	The set of rules that was enabled for the .NET 5.0 release is used, even if newer rules are available.
5	The set of rules that was enabled for the .NET 5.0 release is used, even if newer rules are available.

AnalysisMode values

The following table shows the available AnalysisMode options.

Value	Meaning
minimum	Minimum or highly-recommended set of code analyzers are enabled. This is the default.
none or AllDisabledByDefault	No code analyzers are enabled. This is the most conservative analysis mode.
default	Default set of code analyzers are enabled.
recommended	Recommended set of code analyzers are enabled.
all or AllEnabledByDefault	All code analyzers are enabled. This is the most aggressive analysis mode.

Input Examples

1. Enable all CAxxxx and IDExxxx rules for a single solution at repo root, such that code analysis violations break the build.

   - name: Run .NET Code Analysis
     uses: dotnet/code-analysis@v1
     id: code-analysis
     with:
       solution: MySolution.sln
       build-breaking: true
       all-categories: all
   

2. Enable all 5.0 release CAxxxx security and performance rules, but only the recommended set for other rule categories for MyProject1.csproj and MyProject2.csproj, such that code analysis violations do not break the build.

   - name: Run .NET Code Analysis
     uses: dotnet/code-analysis@v1
     id: code-analysis
     with:
       projects: src\MyProject1.csproj;src\MyProject2.csproj
       build-breaking: false
       security: 5.0-all
       performance: 5.0-all
       all-categories: 5.0-recommended
   

3. Enable highly-recommended IDExxxx code-style rules, and disable all the remaining rules for a single project, such that code analysis violations break the build.

   - name: Run .NET Code Analysis
     uses: dotnet/code-analysis@v1
     id: code-analysis
     with:
       project: src\MyProject1.csproj
       build-breaking: true
       style: minimum
       all-categories: none
   

Outputs

The action produces a JSON format error log file in SARIF format. This file can be uploaded via the github/codeql-action/upload-sarif action.

Usage

See action.yml

Basic

Run .NET code quality and code style analysis that ship with the .NET SDK.

steps:
- uses: actions/checkout@v2

# Run NuGet restore for each project/solution to analyze
- name: Run NuGet restore
  run: dotnet restore <%path_to_project_or_solution%>

# Run code analysis for all projects/solutions, such that code analysis violations break the build.
- name: Run .NET Code Analysis
  uses: dotnet/code-analysis@v1
  id: code-analysis
  with:
    build-breaking: true

Note: The Microsoft Code Analysis CLI is built with dotnet v3.1.201. A version greater than or equal to v3.1.201 of dotnet must be installed on the runner in order to run this action. GitHub hosted runners already have a compatible version of dotnet installed. To ensure a compatible version of dotnet is installed on a self-hosted runner, please configure the actions/setup-dotnet action.

- uses: actions/setup-dotnet@v1
  with:
    dotnet-version: '3.1.x'

Limitations

The .NET code analysis action is currently in beta and runs on the windows-latest queue, as well as Windows self hosted agents. ubuntu-latest support coming soon.
