resolve-project-references

Guide for interpreting ResolveProjectReferences time in MSBuild performance summaries. Activate when ResolveProjectReferences appears as the most expensive target and developers are trying to optimize it directly. Explains that the reported time includes wait time for dependent project builds and is misleading. Guides users to focus on task self-time instead. Do not activate for general build performance -- use build-perf-diagnostics instead.

Misleading ResolveProjectReferences Time

Prevent misguided optimization of ResolveProjectReferences by explaining that its reported time is wall-clock wait time, not CPU work.

When to Use

  • ResolveProjectReferences appears as the most expensive target in the Target Performance Summary
  • A developer is trying to optimize ResolveProjectReferences directly
  • Build performance analysis shows a single target consuming 50-80% of total build time

When Not to Use

  • General build performance optimization (use build-perf-diagnostics instead)
  • The bottleneck is clearly a different target (e.g., Csc, ResolveAssemblyReference)
  • The user has not yet captured a binlog or performance summary

Inputs

InputRequiredDescription
Build log or binlogYesA diagnostic build log or binlog containing the Target Performance Summary

Workflow

Step 1: Confirm the misleading symptom

Verify that ResolveProjectReferences appears as the top target in the Target Performance Summary. This is the misleading metric.

Step 2: Explain why it is misleading

The reported time includes waiting for dependent projects to build while the MSBuild node is yielded (see dotnet/msbuild#3135). During this wait, the node may be doing useful work on other projects. The target itself does very little work.

Step 3: Redirect to task self-time

Use the Task Performance Summary to identify the real bottleneck.

Primary: binlog MCP (preferred)

Use the binlog MCP server expensive_tasks tool to get task self-time rankings directly from the binlog.

Fallback: text-log replay (when MCP is unavailable)

dotnet msbuild build.binlog -noconlog -fl "-flp:v=diag;logfile=full.log;performancesummary"
grep "Task Performance Summary" -A 50 full.log

Focus on self-time of actual tasks:

  • Csc: see build-perf-diagnostics skill (Section 2: Roslyn Analyzers)
  • ResolveAssemblyReference: see build-perf-diagnostics skill (Section 1: RAR)
  • Copy: see build-perf-diagnostics skill (Section 4: File I/O)
  • Serialization bottlenecks: see build-parallelism skill

Validation

  • Task Performance Summary was used instead of Target Performance Summary
  • ResolveProjectReferences was not set as the optimization target
  • A concrete task (e.g., Csc, Copy, ResolveAssemblyReference) was identified as the true bottleneck

Use a repo-root `.editorconfig` to configure free .NET analyzer and style rules. Use when a .NET repo needs rule severity, code-style options, section layout, or analyzer ownership made explicit. USE FOR: the repo needs a root .editorconfig; analyzer severity and style ownership are unclear; the team wants one source of truth for rule configuration. DO NOT USE FOR: choosing analyzers with no config change; formatting-only execution with no config ownership question. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

Symbolicate the .NET runtime frames in an Android tombstone file. Extracts BuildIds and PC offsets from the native backtrace, downloads debug symbols from the Microsoft symbol server, and runs llvm-symbolizer to produce function names with source file and line numbers. USE FOR triaging a .NET MAUI or Mono Android app crash from a tombstone, resolving native backtrace frames in libmonosgen-2.0.so or libcoreclr.so to .NET runtime source code, or investigating SIGABRT, SIGSEGV, or other native signals originating from the .NET runtime on Android. DO NOT USE FOR pure Java/Kotlin crashes, managed .NET exceptions that are already captured in logcat, or iOS crash logs. INVOKES Symbolicate-Tombstone.ps1 script, llvm-symbolizer, Microsoft symbol server.

Symbolicate .NET runtime frames in Apple platform .ips crash logs (iOS, tvOS, Mac Catalyst, macOS). Extracts UUIDs and addresses from the native backtrace, locates dSYM debug symbols, and runs atos to produce function names with source file and line numbers. Automatically downloads .dwarf symbols from the Microsoft symbol server using Mach-O UUIDs. USE FOR triaging a .NET MAUI or Mono app crash from an .ips file on any Apple platform, resolving native backtrace frames in libcoreclr or libmonosgen-2.0 to .NET runtime source code, retrieving .ips crash logs from a connected iOS device or iPhone, or investigating EXC_CRASH, EXC_BAD_ACCESS, SIGABRT, or SIGSEGV originating from the .NET runtime. DO NOT USE FOR pure Swift/Objective-C crashes with no .NET components, or Android tombstone files. INVOKES Symbolicate-Crash.ps1 script, atos, dwarfdump, idevicecrashreport.

Design or review .NET solution architecture across modular monoliths, clean architecture, vertical slices, microservices, DDD, CQRS, and cloud-native boundaries without over-engineering. USE FOR: .NET architecture choices; layer and domain boundary review; service decomposition; clean architecture, vertical slice, DDD, CQRS, and modular monolith decisions. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.
