Analyzer package

Example: Microsoft.CodeAnalysis.FxCopAnalyzers

Package Version

Example: v2.9.4 (Latest)

Diagnostic ID

Example: CA1716

Repro steps

  1. Enlist into https://github.com/w5wc/Thetis/tree/master/Project%20Files/Source
  2. Add an editorconfig file to both C# projects in the solution with entry dotnet_code_quality.CA2213.interprocedural_analysis_kind = ContextSensitive to turn on complete interprocedural analysis for the project

Expected behavior

Analyzes solution with reasonable performance characteristics

Actual behavior

Runs into OOM - see https://developercommunity.visualstudio.com/content/problem/672009/live-analysis-eats-up-memory-resulting-in-vs-crash.html?childToView=681646#comment-681646
