InvariantStringHelper 1.0.0

CopilotAIWorkflow packages

NuGet packages from CopilotAIWorkflow — agent workflow tooling with mechanical quality gates.

Release 1.2.0 — InvariantStringHelper 1.0.0 is new; CSharpStyleChecker 1.2.0 accepts and recommends it in CSC009 (1.1.0 rejects the helper); breaking on .NET 6+: CSC009 now also rejects FormattableString.Invariant; ExitPointGaps 1.1.1 uses the helper. 1.1.0 shipped CSC009 plus CSC001–CSC008 fixes. Version line restarted at 1.0.0 (not a continuation of the pre-rebrand 2.x line).

CSharpStyleChecker

Roslyn analyzer enforcing C# style as compiler errors (CSC001–CSC009). Add as a development dependency:

<PackageReference Include="CSharpStyleChecker" Version="1.*" />

Analyzers load from analyzers/dotnet/cs (includes bundled ExitPoints.dll). See README.md — CSharpStyleChecker.

Replaces: CSharpStyleValidator (rule IDs CSV* → CSC*).

InvariantStringHelper

Invariant-culture string interpolation for .NET 6 and later that allocates only the result string.

<PackageReference Include="InvariantStringHelper" Version="1.*" />

global using static InvariantStringHelper.InvariantText;

string message = Invariant($"Rejection rate: {rate:P1}, count={count}");

No dependencies. netstandard2.0 is not supported. Together with CSharpStyleChecker use 1.2.0 or later: 1.1.0 reports the call as CSC009. See README.md — InvariantStringHelper.

ExitPointGaps

Local dotnet tool — lists exit-point gaps (exitGaps[]) from Cobertura and Roslyn exit-point collection. Analysis is integrated into the tool assembly (no separate library package).

dotnet new tool-manifest
dotnet tool install ExitPointGaps --version 1.*
dotnet tool run exitpointgaps --repo-root .

Requires .NET SDK 10.0, MTP + TUnit in test projects. Gate: summary.exitGapCount == 0. Multi-project summaries use schema v3 (reportFile indirection). Workflow SSOT: tech-tunit.md. User quickstart: README.md §2.

Replaces: CoverageGap.Tool + CoverageGapAnalysis.

Performance (1.0.0)

• Per-project parallelism by default; cap with --max-parallelism <n>
• Solution pre-build once, then --no-build for repeat runs
• Scoped Cobertura parse, streaming writes, Roslyn Compilation dropped after exit collection
• Benchmark (this repo, Release, --no-build): serial ~22.8s → parallel ~12.0s (~47% faster)

Details: CSharpStyleChecker CHANGELOG, ExitPointGaps CHANGELOG, repo CHANGELOG.md.

Migration

Requirements

Repo clone: Directory.Build.targets auto-applies CSharpStyleChecker (opt out with ApplyCSharpStyleChecker=false). NuGet consumers use PackageReference on each project that should enforce CSC rules; not transitive to downstream libraries.
