Skill instructions
MSBuild Evaluation Phases For a comprehensive overview of MSBuild's evaluation and execution model, see Build process overview. 1. Initial properties: environment variables, global properties, reserved properties 2. Imports and property evaluation: process <Import, evaluate <PropertyGroup top-to-bottom 3. Item definition evaluation: <ItemDefinitionGroup metadata defaults 4. Item evaluation: <ItemGroup with Include, Remove, Update, glob expansion 5. UsingTask evaluation: register custom tasks Key insight: evaluation happens BEFORE any targets run. Slow evaluation = slow build start even when nothing needs compiling. Diagnosing Evaluation Performance Primary: binlog MCP (preferred) Use the binlog MCP server (Microsoft.AITools.BinlogMcp, exposed under the binlog MCP namespace) to analyze evaluation performance: 1. Use the evaluations tool to list all evaluations and their durations 2. Use evaluationglobalproperties to check for multiple evaluations with differing global properties 3. Use
