Durable Task Roslyn Analyzer (C# only)

dotnet add package Microsoft.DurableTask.Analyzers

How it works

The analyzer runs automatically in Visual Studio, Visual Studio Code (with the C# Dev Kit extension), and during dotnet build on the command line. It inspects your orchestrator code and reports diagnostics as warnings or errors in your IDE's error list and in build output.

No special IDE configuration is required. The analyzer activates as soon as the NuGet package is present in your project.

Analyzer rules

The following table lists the analyzer rules that ship with the Durable Task Roslyn Analyzer. Each rule targets a specific code constraint violation or common mistake.

For more information, see the analyzer release notes on GitHub.

Suppress analyzer warnings

You can suppress analyzer diagnostics at the project, file, or line level.

Suppress with .editorconfig

Add an entry to your .editorconfig file to change the severity of a rule or disable it entirely:

[*.cs]
dotnet_diagnostic.DURABLE0001.severity = none

Valid severity values are error, warning, suggestion, silent, and none.

Suppress inline with #pragma

Use #pragma warning disable to suppress a specific warning in a section of code:

#pragma warning disable DURABLE0001
var now = DateTime.UtcNow;
#pragma warning restore DURABLE0001

Suppress at the project level

Add a <NoWarn> entry to your .csproj file to suppress a rule for the entire project:

<PropertyGroup>
  <NoWarn>$(NoWarn);DURABLE0001</NoWarn>
</PropertyGroup>
