Troubleshooting

"dotnet: command not found" → Install .NET SDK 8.0 from https://dotnet.microsoft.com/download/dotnet/8.0

"OfficeAutomator.Core.csproj not found" → Ensure you're in the OfficeAutomator.Core directory

"Tests not discovered" → Verify all *Tests.cs files are present (should be 11)

"Restore failed" → Clear NuGet cache: dotnet nuget locals all --clear

See TESTING_SETUP.md for more troubleshooting.
