…jects (#5994) This allows additional properties to be gathered from project references via the project reference protocol. This is in order to support generating an error when a self-contained Executable references a non-SelfContained Executable, or vice versa, as described in dotnet/sdk#15117. The referenced project can declare what additional properties should be gathered with AdditionalTargetFrameworkInfoProperty items: <ItemGroup> <AdditionalTargetFrameworkInfoProperty Include="SelfContained"/> <AdditionalTargetFrameworkInfoProperty Include="_IsExecutable"/> </ItemGroup> These items will then be included in the AdditionalPropertiesFromProject metadata on the _MSBuildProjectReferenceExistent items. This value will have PropertyName=PropertyValue combinations joined by semicolons, and those sets of properties for the different TargetFramework values will be joined by double semicolons. For example, a project multitargeted to two TargetFrameworks may have the following for the AdditionalPropertiesFromProject metadata: SelfContained=true;_IsExecutable=true;;SelfContained=false;_IsExecutable=true Finding the right set of properties from the referenced project will required looking up the index of the NearestTargetFramework in the TargetFrameworks, and using that index to select the set of properties in the AdditionalPropertiesFromProject metadata. For example: string nearestTargetFramework = project.GetMetadata("NearestTargetFramework"); int targetFrameworkIndex = project.GetMetadata("TargetFrameworks").Split(';').ToList().IndexOf(nearestTargetFramework); string projectAdditionalPropertiesMetadata = project.GetMetadata("AdditionalPropertiesFromProject").Split(new[] { ";;" }, StringSplitOptions.None)[targetFrameworkIndex]; Dictionary<string, string> projectAdditionalProperties = new(StringComparer.OrdinalIgnoreCase); foreach (var propAndValue in projectAdditionalPropertiesMetadata.Split(';')) { var split = propAndValue.Split('='); projectAdditionalProperties[split[0]] = split[1]; } This is implemented in dotnet/sdk#15134.
