I think I have discovered a performance issue with resource generation on large builds – it is VB specific.
Long story short: For each resource file in a project, the entire reference structure of your project is traversed and every referenced project is traversed, repeat recursively.
Basically: The Resource class, in the CompileResx method, creates a ResGenTask then iterates through each reference and adds dependent assemblies to the ResGenTask:
Resource.cs (line 357)
foreach (ReferenceBase reference in Project.References) {
StringCollection assemblyReferences = reference.GetAssemblyReferences(
solutionConfiguration);
foreach (string assemblyFile in assemblyReferences) {
rt.Assemblies.Includes.Add(assemblyFile);
}
}
ProjectReferenceBase.GetAssemblyReferences() calls ProjectBase.GetAssemblyReferences() – but only for VB projects:
ProjectReferenceBase.cs (line 146)
// check if parent is a VB.NET project
if (typeof(VBProject).IsAssignableFrom(Parent.GetType())) {
assemblyReferences = Project.GetAssemblyReferences(solutionConfiguration);
} else {
assemblyReferences = new StringCollection();
}
ProjectBase.GetAssemblyReferences() loops through each reference and calls ProjectReferenceBase.GetAssemblyReferences()
ProjectBase.cs (line 335)
foreach (ReferenceBase reference in References) {
StringCollection references = reference.GetAssemblyReferences(solutionConfiguration);
...
Here is a sample stack trace:
