Use libdatadog for dotnet by NachoEchevarria · Pull Request #8186 · DataDog/dd-trace-dotnet

NachoEchevarria · 2026-02-10T16:47:57Z

Summary of changes

Migrate native dependency from DataDog/libdatadog to DataDog/libdatadog-dotnet v1.2.29.

Reason for change

libdatadog-dotnet is a .NET-specific fork of libdatadog with a minimal feature preset tailored to the needs of the .NET tracer, resulting in smaller binaries and a more focused build.

Implementation details

Updated build/cmake/FindLibdatadog.cmake: version, download URLs, and SHA256 hashes for all 6 Linux/macOS platform variants
Updated build/vcpkg_local_ports/libdatadog/portfile.cmake: download URL and SHA512 hashes for both Windows variants (x64, x86)
Updated build/vcpkg_local_ports/libdatadog/vcpkg.json: version string to 1.2.29

All download URLs changed from github.com/DataDog/libdatadog to github.com/DataDog/libdatadog-dotnet.

Test coverage

No test changes — this is a dependency version/source update. Existing CI builds and native profiler tests validate the binary compatibility.

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
