[solrevdev]

What changed

• src/solrevdev.seedfolder.csproj: targets net10.0, plus net11.0 when the SDK is 11.0 or later (was net8.0;net9.0;net10.0). RollForward stays Major. Version bumped 1.6.2 to 1.7.0. Package description and release notes now name .NET 10 and .NET 11 only.
• global.json (new): { "sdk": { "version": "10.0.100", "rollForward": "latestMajor", "allowPrerelease": false } }.
• .github/workflows/ci.yml: setup-dotnet installs 10.0.x and 11.0.x explicitly. Integration tests run once per target framework.
• .github/workflows/ci.yml: a new check package targets step runs right after dotnet pack. It fails the run if the nupkg lacks tools/net10.0/ or tools/net11.0/. It runs before the NuGet login, publish and tag steps.
• tests/integration-test.sh and tests/integration-test.ps1: take the target framework as an argument (default net10.0). They hardcoded net8.0, so CI would have failed after this change.
• AGENTS.md, .github/copilot-instructions.md, README.md, .vscode/launch.json: name net10.0 and net11.0 only and describe the SDK policy. README "Run tests" now points at the integration scripts, since there is no dotnet test project.

Why

On 11 Nov 2026 John decided the project follows supported .NET versions only: tools and tests target net10.0;net11.0, and nothing targets 8 or 9. .NET 8 and .NET 9 left support on 10 Nov 2026.

SDK policy

.NET 10 is the LTS and the baseline.

• global.json pins SDK 10.0.100 with rollForward: latestMajor, so the newest installed release SDK is used.
• Only SDK 11: builds and works (latestMajor picks 11).
• SDK 10 and 11: uses 11 and builds both targets.
• Only SDK 10: builds and works, net10.0 only.

Conditional target

<!-- The published package needs both targets; CI installs both SDKs so it ships both, and SDK 10 alone builds net10.0 only. -->
<TargetFrameworks>net10.0</TargetFrameworks>
<TargetFrameworks Condition="$([MSBuild]::VersionGreaterThanOrEquals('$(NETCoreSdkVersion)', '11.0'))">net10.0;net11.0</TargetFrameworks>

CI installs both SDKs, so latestMajor selects SDK 11 there and the published package always holds tools/net10.0 and tools/net11.0.

Package target check

The targets in the package depend on the SDK that built it. This step stops a release that would ship without one:

set -euo pipefail
# The targets depend on the SDK that built them; fail rather than
# ship a package missing one.
version=$(sed -n 's:.*<Version>\(.*\)</Version>.*:\1:p' src/solrevdev.seedfolder.csproj)
# Name the exact file: a glob would also match the symbols package,
# and unzip reads any extra argument as a member filter.
LISTING=$(unzip -l "src/nupkg/solrevdev.seedfolder.${version}.nupkg")
for tfm in net10.0 net11.0; do
  grep -q "tools/$tfm/any/solrevdev.seedfolder.dll" <<<"$LISTING" \
    || { echo "Package is missing tools/$tfm" >&2; exit 1; }
done

Step order: build, integration tests (net10.0), integration tests (net11.0), pack, check package targets, verify versioned package, NuGet login, publish. tag-release runs only after publish succeeds.

I extracted the step script from ci.yml and ran it locally against CI-style packs:

• SDK 11.0.100, fresh build and pack: the package holds tools/net10.0/any/solrevdev.seedfolder.dll and tools/net11.0/any/solrevdev.seedfolder.dll. The check passed with exit 0.
• Scratch worktree pinned to SDK 10.0.404 with rollForward: disable: the package holds only tools/net10.0/any/solrevdev.seedfolder.dll. The check failed with exit 1 and printed Package is missing tools/net11.0. The worktree was removed afterwards.

Install compatibility

Dropping net8.0 and net9.0 means a machine with only the .NET 8 or .NET 9 runtime can no longer install new releases. Those users must install .NET 10 or later, or stay on 1.6.2. This is why the first commit is marked feat!. The version bump is minor per John's call.

Merging may publish to NuGet

CI publishes to NuGet on push to master and then tags v1.7.0. Merging this PR will likely release 1.7.0, so merging is John's call. This PR has not been merged.

Verification

Local macOS machine with SDKs 10.0.404 and 11.0.100 and runtimes 10.0.15 and 11.0.0. No global tool, SDK or runtime was changed.

(a) Normal run: SDK 11 via latestMajor

$ dotnet --version
11.0.100

$ dotnet build solrevdev.seedfolder.sln -c Release
  solrevdev.seedfolder -> .../src/bin/Release/net10.0/solrevdev.seedfolder.dll
  solrevdev.seedfolder -> .../src/bin/Release/net11.0/solrevdev.seedfolder.dll
    0 Warning(s)
    0 Error(s)

Script	net10.0	net11.0
tests/integration-test.sh <tfm>	pass, 18 checks, 0 failures	pass, 18 checks, 0 failures
tests/integration-test.ps1 -Framework <tfm>	pass, 17 checks, 0 failures	pass, 17 checks, 0 failures

$ dotnet pack solrevdev.seedfolder.sln -c Release -o <scratch>/a/nupkg
  Successfully created package '<scratch>/a/nupkg/solrevdev.seedfolder.1.7.0.nupkg'.

$ unzip -l solrevdev.seedfolder.1.7.0.nupkg   (tools/ folders)
tools/net10.0
tools/net11.0

(b) SDK 10 only

A scratch git worktree with global.json set to {"sdk":{"version":"10.0.404","rollForward":"disable"}}. That pin was not committed, and the worktree was removed afterwards.

$ dotnet --version
10.0.404

$ dotnet build solrevdev.seedfolder.sln -c Release
  solrevdev.seedfolder -> .../src/bin/Release/net10.0/solrevdev.seedfolder.dll
    0 Warning(s)
    0 Error(s)

Only net10.0 was built. Forcing -f net11.0 fails with NETSDK1045 as expected, which shows the condition is what keeps SDK 10 builds working.

Script	net10.0
tests/integration-test.sh net10.0	pass, 18 checks, 0 failures
tests/integration-test.ps1 -Framework net10.0	pass, 17 checks, 0 failures

$ unzip -l solrevdev.seedfolder.1.7.0.nupkg   (tools/ folders)
tools/net10.0

$ dotnet tool install --tool-path <scratch>/b/tools --add-source <scratch>/b/nupkg solrevdev.seedfolder --version 1.7.0
