Pull Request Overview
This PR updates the DTB evaluation to leverage ProjectGraph, refactoring how evaluation results are created and used throughout dotnet‐watch and its test suites.
- Updates test and production code to use MSBuildFileSetFactory.EvaluationResult instead of a custom EvaluationResult type.
- Adjusts file watching and project graph loading logic to use the project path from the current context.
- Revises test expectations and build arguments to align with the new evaluation approach.

Remove usage of
MSBuildFileSetFactory
andDotNetWatch.targets
for design-time build performed by dotnet-watch Hot Reload.Replace the logic using
ProjectGraph
evaluation. Avoids launching additionaldotnet build
just to perform design-time builds.The next step would be to switch the implementation to use Roslyn MSBuild host APIs to avoid duplicating DTB logic (both at runtime and implementation details).
Keeps the original implementation around for
dotnet-watch --no-hot-reload
for now.Implements #40214
Fixes #49542
Fixes #49115
