NuGet RestoreAdditionalProjectSources package source mapping exact package ID multiple sources same version source selection official documentation

💡 Result:

NuGet does not support prioritization of package sources during restore [1][2][3]. When multiple sources are configured, NuGet attempts to retrieve packages from all of them in parallel, and the restore process is non-deterministic regarding which source is used if the same package ID and version exist in multiple locations [4][2]. To achieve deterministic restore behavior and control source selection, you must use Package Source Mapping [4][5]. Package Source Mapping allows you to explicitly define which source(s) NuGet should search for specific packages [4][6]. This is the recommended approach to resolve ambiguity when a package ID exists in multiple sources [4][5]. Key rules for Package Source Mapping include: 1. Pattern Precedence: When multiple patterns match a package ID, the most specific (longest) match takes precedence [4][5]. Exact package ID patterns have the highest precedence, while the generic * (wildcard) pattern has the lowest [4][5]. 2. Comprehensive Mapping: Once you define a packageSourceMapping section, you must explicitly map every package used in the solution, including all transitive dependencies [4][6]. 3. Multiple Sources for a Pattern: While you can map the same package ID pattern to multiple sources, it is not recommended because it prevents predictable source selection [4][7]. Regarding RestoreAdditionalProjectSources, this property adds package sources to the restore process just as if they were defined in your NuGet.config file [3]. It does not introduce any priority or selection logic; these added sources are treated equally alongside all other configured sources [2][3]. In summary, reliance on source order or "priority" is not supported and will not reliably resolve conflicts [1][2]. The official and supported solution is to implement Package Source Mapping in your NuGet.config file to enforce specific source usage for specific package IDs [4][5].

Citations:

Restrict Expressif.Syntax to the downloaded package source.

RestoreAdditionalProjectSources does not prioritize the artifact directory. If another feed contains the same package ID and version, NuGet can restore that package instead. Create a temporary NuGet config that maps Expressif.Syntax only to artifacts and maps * to the normal feed for test dependencies. Pass it with --configfile in both restore steps: .github/workflows/ci.yml and .github/workflows/release.yml.
