Analyzers

Modular Pipelines includes Roslyn analyzers that catch pipeline authoring mistakes at compile time. Each rule uses the MP#### ID family, so it can be configured with standard .NET analyzer settings.

See the complete analyzer rule reference for every rule, its category, default severity, and suppression examples.

Configure a rule

Set a rule's severity in .editorconfig:

[*.cs]
dotnet_diagnostic.MP0001.severity = warning

Valid values are default, none, silent, suggestion, warning, and error. Use none to disable a rule.

Suppress a specific occurrence

Use #pragma when a violation is intentional and narrowly scoped:

#pragma warning disable MP0001
// Code that intentionally violates MP0001.
#pragma warning restore MP0001

ID migration

The legacy prose IDs were renamed so .editorconfig settings can use one predictable family:

Legacy ID	Current ID
MissingDependsOnAttribute	MP0001
EnumerableModuleResult	MP0002
LoggerInConstructor	MP0003
ConsoleUse	MP0004
ConflictingDependsOnAttribute	MP0005
AsyncModule	MP0006
AwaitThis	MP0007
StatefulModule	MP0008
MPDEP001	MP0009
MPDEP002	MP0005
MPDEP003	MP0010
MPREG001	MP0013
MPASYNC001	MP0014
MPASYNC002	MP0015
MPASYNC003	MP0016
MPASYNC004	MP0017
MPTYPE001	MP0018
MPDEP004	MP0019

Update existing dotnet_diagnostic.<id>.severity entries and warning suppressions to the current IDs.

V3-to-V4 upgrade code fixes

After upgrading the core and integration packages to V4, use Upgrade to ModularPipelines V4 from your editor's quick actions on compiler errors CS1061, CS0117, or CS1739. These fixes cover:

• Tool access, such as context.Git() becoming context.Tools.Git.
• Methods renamed with an Async suffix.
• Named arguments renamed from token: to cancellationToken:.
• Git commands moved into a command group, discovered from the installed IGitCommands API.
• Legacy ModuleStatus names, including Successful becoming Succeeded and Processing becoming Running.

For example, apply the tool-access fix and then the command fix to migrate:

await context.Git().Commands.Config(options, token: cancellationToken);

into:

using ModularPipelines.Context;

await context.Tools.Git.Commands.Repository.ConfigAsync(options, cancellationToken: cancellationToken);

Fixes bind each proposed replacement against the APIs installed in your project. A replacement is offered only when it resolves without errors to a ModularPipelines member. Ambiguous Git groups and calls whose arguments also need manual changes are left for you to resolve. Import ModularPipelines.Context, where the source generator emits the tool extension properties; an old import such as ModularPipelines.Git.Extensions does not expose them. Extension properties require a C# 14-capable editor/compiler.

Use Fix All for independent occurrences. A chain of old calls can expose a new compiler error after the first fix; apply the next quick action or repeat Fix All until the mechanical changes are complete. Review the resulting code: these fixes do not add await, change option types, register integrations, or handle every V4 breaking change.
