[tdav]

Summary

Final PR of the SmAutoMapper 1.1.0 cleanup release. Bumps the package version, adds a CHANGELOG.md, and updates README usage examples to the DI-injected IProjectionProvider pattern introduced in PR #3.

Changes

• Version bump — <Version>1.0.2</Version> → <VersionPrefix>1.1.0</VersionPrefix> in src/SmAutoMapper/SmAutoMapper.csproj
• CHANGELOG.md — new file covering Added / Changed / Deprecated / Removed / Performance for 1.1.0 (summarizes PRs PR #1: CI gate + SourceLink + housekeeping (1.1.0) #1–release/1.1.0 (3/6): AOT + Trimming attributes on public API #5)
• README — 5 code examples migrated from legacy source.ProjectTo<Dto>() to recommended source.ProjectTo<Src, Dto>(projections, ...) (Quick Start, ProjectTo API, nested-collection example, Web API controller, category-tree controller). Adds a callout referencing SMAM0002 and the Migrating guide.

Verification

• dotnet build -c Release: 0 warnings, 0 errors
• dotnet test -c Release --no-build: 82 passed, 1 skipped (pre-existing), 0 failed
• dotnet pack: both SmAutoMapper.1.1.0.nupkg and SmAutoMapper.1.1.0.snupkg produced
• .nuspec inspection: id=SmAutoMapper, version=1.1.0, repository commit hash embedded (SourceLink working)

After merge

• Tag v1.1.0 and create GitHub release
• publish.yml will push .nupkg + .snupkg to NuGet
• Sandbox smoke test: dotnet add package SmAutoMapper --version 1.1.0

Test plan

• nupkg and snupkg both produced by dotnet pack
• Metadata validated (id, version, repo commit, dependencies)
• All tests pass, build is clean with analyzers on
• CI green on this PR before merge
• Post-merge: v1.1.0 tag + GitHub release + NuGet push (performed separately with user authorization)
