ModularPipelines V3 Release Notes
Highlights
ASP.NET Core-Style Builder Pattern

No more callbacks. Direct property access, just like ASP.NET Core minimal APIs.

// Before (V2)
await PipelineHostBuilder.Create()
    .ConfigureAppConfiguration((context, builder) => { ... })
    .ConfigureServices((context, collection) => { ... })
    .ExecutePipelineAsync();

// After (V3)
var builder = Pipeline.CreateBuilder(args);
builder.Configuration.AddJsonFile("appsettings.json");
builder.Services.AddModule<BuildModule>();
await builder.Build().RunAsync();

If you've used ASP.NET Core, this feels instantly familiar.

Fluent Module Configuration

Configure module behavior with a clean, fluent API instead of scattered property overrides.

// Before (V2) - properties scattered across the class
protected internal override TimeSpan Timeout => TimeSpan.FromMinutes(5);
protected override AsyncRetryPolicy<string?> RetryPolicy => ...;
protected internal override Task<SkipDecision> ShouldSkip(...) => ...;

// After (V3) - everything in one place
protected override ModuleConfiguration Configure() => ModuleConfiguration.Create()
    .WithTimeout(TimeSpan.FromMinutes(5))
    .WithRetryCount(3)
    .WithSkipWhen(ctx => ctx.Git().Information.BranchName != "main"
        ? SkipDecision.Skip("Only runs on main")
        : SkipDecision.DoNotSkip)
    .Build();
Type-Safe Result Handling

Module results are now discriminated unions. Pattern matching gives you compile-time safety.

var result = await context.GetModule<BuildModule>();

return result switch
{
    ModuleResult<BuildOutput>.Success { Value: var output } => Deploy(output),
    ModuleResult.Skipped => null,
    ModuleResult.Failure { Exception: var ex } => throw ex,
    _ => null
};

Or use the simpler helpers for quick migrations:

if (result.IsSuccess)
{
    var value = result.ValueOrDefault;
}
New Features
Non-Generic Module Classes

New Module and SyncModule base classes for modules that don't return data.

// Async module - no return value needed
public class DeployModule : Module
{
    protected override async Task ExecuteModuleAsync(
        IModuleContext context, CancellationToken cancellationToken)
    {
        await context.Command.ExecuteCommandLineTool(...);
    }
}

// Sync module - no return value needed
public class LoggingModule : SyncModule
{
    protected override void ExecuteModule(
        IModuleContext context, CancellationToken cancellationToken)
    {
        context.Logger.LogInformation("Done!");
    }
}

Internally these use the None struct, which represents "nothing" and is semantically equivalent to null.

Dynamic Dependencies

Declare dependencies programmatically based on runtime conditions.

protected override void DeclareDependencies(IDependencyDeclaration deps)
{
    deps.DependsOn<RequiredModule>();
    deps.DependsOnOptional<OptionalModule>();
    deps.DependsOnIf<ProductionModule>(Environment.IsProduction);
}
Powerful Dependency Attributes
// Depend on all modules in a category
[DependsOnModulesInCategory("Build")]
public class TestModule : Module<TestResults> { }

// Depend on all modules with a tag
[DependsOnModulesWithTag("database")]
public class MigrationModule : Module<bool> { }
Conditional Execution Attributes
[RunOnLinux]
public class LinuxModule : Module<string> { }

[RunOnWindowsOnly]  // Skips on other platforms
public class WindowsOnlyModule : Module<string> { }

[SkipIf(typeof(IsNotMainBranchCondition))]
public class MainBranchModule : Module<string> { }

[RunIfAll(typeof(IsCI), typeof(IsMainBranch))]
public class CIMainModule : Module<string> { }
Module Tags and Categories

Organize modules for easier management.

[ModuleTag("critical")]
[ModuleTag("deployment")]
[ModuleCategory("Infrastructure")]
public class DeployModule : Module<DeployResult> { }
Pipeline Validation

Catch configuration errors before execution.

var validation = await builder.ValidateAsync();
if (validation.HasErrors)
{
    foreach (var error in validation.Errors)
    {
        Console.WriteLine($"[{error.Category}] {error.Message}");
    }
}
Plugin System

Create reusable pipeline extensions.

public class MyPlugin : IModularPipelinesPlugin
{
    public string Name => "MyPlugin";

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddSingleton<IMyService, MyService>();
    }

    public void ConfigurePipeline(PipelineBuilder builder)
    {
        builder.Services.AddModule<PluginModule>();
    }
}

[assembly: ModularPipelinesPlugin(typeof(MyPlugin))]
Enhanced Lifecycle Hooks

New overridable methods for fine-grained control.

protected override Task OnBeforeExecuteAsync(IModuleContext context, CancellationToken ct) { }
protected override Task OnAfterExecuteAsync(IModuleContext context, ModuleResult<T> result, CancellationToken ct) { }
protected override Task OnSkippedAsync(IModuleContext context, SkipDecision decision, CancellationToken ct) { }
protected override Task OnFailedAsync(IModuleContext context, Exception ex, CancellationToken ct) { }
Breaking Changes
Entry Point
V2 V3
PipelineHostBuilder.Create() Pipeline.CreateBuilder(args)
.ConfigureAppConfiguration(callback) builder.Configuration
.ConfigureServices(callback) builder.Services
.ConfigurePipelineOptions(callback) builder.Options
.AddModule<T>() on builder builder.Services.AddModule<T>()
.ExecutePipelineAsync() .Build().RunAsync()
Module API
V2 V3
IPipelineContext in ExecuteAsync IModuleContext
GetModule<T>() on module context.GetModule<T>()
Timeout property override Configure().WithTimeout()
RetryPolicy property override Configure().WithRetryCount()
ShouldSkip() method Configure().WithSkipWhen()
ShouldIgnoreFailures() method Configure().WithIgnoreFailures()
ModuleRunType.AlwaysRun Configure().WithAlwaysRun()
OnBeforeExecute() Configure().WithBeforeExecute() or OnBeforeExecuteAsync()
OnAfterExecute() Configure().WithAfterExecute() or OnAfterExecuteAsync()
Result Access
V2 V3
result.Value result.ValueOrDefault or pattern match
result.Exception result.ExceptionOrDefault or pattern match
result.ModuleResultType == ModuleResultType.Success result.IsSuccess or pattern match
Command Execution

Execution-related properties moved from tool options to a separate CommandExecutionOptions parameter:

V2 (on tool options) V3 (on CommandExecutionOptions)
WorkingDirectory WorkingDirectory
EnvironmentVariables EnvironmentVariables
ThrowOnNonZeroExitCode ThrowOnNonZeroExitCode 
// V3: Pass execution options as second parameter
await context.DotNet().Build(
    new DotNetBuildOptions { Configuration = "Release" },
    new CommandExecutionOptions { WorkingDirectory = "/app" });
Removed Types
  • PipelineHostBuilder - Use Pipeline.CreateBuilder()
  • ModuleBase / ModuleBase<T> - Use Module<T>
Migration Path
Quick Migration (Minimal Changes)

The ExecutePipelineAsync() extension still exists:

var builder = Pipeline.CreateBuilder(args);
builder.Services.AddModule<MyModule>();
await builder.ExecutePipelineAsync();  // Still works

And ValueOrDefault provides backwards-compatible result access:

var result = await context.GetModule<BuildModule>();
var value = result.ValueOrDefault;  // Similar to old result.Value
Full Migration

For the cleanest code, adopt the new patterns:

  1. Use Pipeline.CreateBuilder(args) with direct property access
  2. Move module configuration to Configure() builder
  3. Change IPipelineContext to IModuleContext
  4. Move GetModule<T>() calls to context
  5. Use pattern matching for result handling

See the Migration Guide for detailed examples.

Upgrade Steps
  1. Update the NuGet package: dotnet add package ModularPipelines --version 3.0.0
  2. Fix compile errors using the migration tables above
  3. (Optional) Refactor to use new fluent APIs
  4. (Optional) Adopt new features like tags, categories, and conditional attributes

This major version update to ModularPipelines v3 introduces significant breaking changes that require code modifications throughout the codebase. The current changes only update package versions without adapting the consuming code.

Critical breaking changes that must be addressed:

  1. Entry Point Changes (build/Program.cs):

    • PipelineHostBuilder.Create() must be changed to Pipeline.CreateBuilder(args)
    • .ConfigureAppConfiguration(callback) must be changed to direct builder.Configuration property access
    • .ConfigureServices(callback) must be changed to direct builder.Services property access
    • .ExecutePipelineAsync() must be changed to .Build().RunAsync()

  2. Module API Changes (all module files):

    • IPipelineContext must be changed to IModuleContext
    • GetModule<T>() called on the module must be changed to context.GetModule<T>()
    • Module result access pattern result.Value must be changed to result.ValueOrDefault or pattern matching

  3. Lifecycle Hook Changes:

    • OnAfterExecute(IPipelineContext context) signature has changed in v3

Without these changes, the build will fail with compilation errors. Please refer to the ModularPipelines v3 migration guide for detailed instructions on updating the code.
