Context

Use this when changing the Web Forms to Blazor CLI markup pipeline anywhere near GridView column transforms, template context handling, data-binding expression rewrites, or asp-prefix stripping. TemplateField preservation is a cross-transform behavior, so regressions can appear even when each individual transform still looks correct in isolation.

Patterns

Treat TemplateField preservation as an ordered pipeline contract:
- DisplayExpressionTransform
- AspPrefixTransform
- DataBindingAttributeTransform
- AttributeStripTransform
- GridViewColumnItemTypeTransform
- TemplateContextTransform
Keep regression coverage at two levels:
1. Transform-only markup assertions through TestHelpers.CreateDefaultPipeline().
2. Full-file migration assertions through MigrationPipeline.ExecuteAsync().
Cover these GridView shapes explicitly:
- TemplateField with inner TextBox
- TemplateField with inner CheckBox
- TemplateField with inline display expression only
- Mixed BoundField + TemplateField siblings
- GridView with only TemplateField columns
Assert both preservation and non-regression:
- Expected <TemplateField ...> count remains stable
- Inner controls survive as BWFC components (<TextBox>, <CheckBox>)
- ItemTemplate Context="Item" is present
- No unexpected fallback <BoundField> appears for template-only columns

Examples

tests/BlazorWebFormsComponents.Cli.Tests/TransformUnit/GridViewColumnItemTypeTransformTests.cs
tests/BlazorWebFormsComponents.Cli.Tests/PipelineIntegrationTests.cs

Anti-Patterns

Testing only GridViewColumnItemTypeTransform in isolation after changing template-related transforms.
Verifying only the first GridView column and assuming later TemplateField siblings survived.
Accepting output that preserves the TemplateField shell but drops nested controls or display expressions.
Changing transform order in Program.cs without mirroring the same coverage through tests/BlazorWebFormsComponents.Cli.Tests/TestHelpers.cs.
