Building and Testing vstest

Pre-Build: Environment Setup

Before building, verify the .dotnet toolchain matches the current OS. The repo bootstraps its own .NET SDK into .dotnet/.

Detect OS vs .dotnet Mismatch

Run this check before every first build in a session:

# Determine current OS
OS=$(uname -s)   # "Linux", "Darwin" (macOS), or contains "MINGW"/"MSYS" (Windows/Git Bash)

if [ -d ".dotnet" ]; then
  if [ "$OS" = "Linux" ] || [ "$OS" = "Darwin" ]; then
    # On Linux/macOS the dotnet binary must be an ELF/Mach-O executable, not .exe
    if [ -f ".dotnet/dotnet.exe" ] && [ ! -f ".dotnet/dotnet" ]; then
      echo "MISMATCH: .dotnet contains Windows binaries but OS is $OS"
      rm -rf .dotnet .packages artifacts
      echo 
    
  
    
     [ -f  ] && [ ! -f  ]; 
       
       -rf .dotnet .packages artifacts
