From a coverage perspective, deterministic builds create some challenges because coverage tools usually need access to complete source file metadata (ie. local path) during instrumentation and report generation. These files are reported inside the `.pdb` files, where debugging information is stored.

In local (non-CI) builds, metadata emitted to pdbs are not "deterministic", which means that source files are reported with their full paths. For example, when we build the same project on different machines we'll have different paths emitted inside pdbs, hence, builds are "non deterministic".

As explained above, to improve the level of security of generated artifacts (for instance, DLLs inside the NuGet package), we need to apply some signature (signing with certificate) and validate before usage to avoid possible security issues like tampering.

Finally, thanks to deterministic CI builds (with the `ContinuousIntegrationBuild` property set to `true`) plus signature we can validate artifacts and be sure that the binary was built from specific sources (because there is no hard-coded variable metadata, like paths from different build machines).

You can merge also running `dotnet test` and merge with single command from a solution file, but you need to ensure that tests will run sequentially(`-m:1`). This slow down testing but avoid invalid coverage result.

N.B. You need to specify `json` format plus another format(the final one), because Coverlet can only merge proprietary format. At the end you can delete temporary `coverage.json` file.

You can also merge the coverage result and generate another valid format to export the content than opencover, like cobertura.
