Pull Request Overview
This PR refactors the .NET trimming documentation to improve clarity and comprehension. The refactoring introduces a new conceptual guide explaining fundamental trim analysis concepts, reorganizes the table of contents into a logical structure (Overview, Concepts, How-to guides, Reference), and rewrites the fixing-warnings guide to provide practical, step-by-step workflows for addressing trim warnings.
Key changes:
- New conceptual documentation explaining how trim analysis works and why patterns produce warnings.
- Enhanced explanations using analogies (comparing
DynamicallyAccessedMembersto generic type constraints) to help developers understand trim contracts. - Restructured navigation with clear categorization of content types.

- Table cells should use complete sentences with proper punctuation per the guidelines. These cells are fragments. Consider rephrasing to imperative sentences, such as 'Use for
Activator.CreateInstance()orGetConstructor().' with periods at the end.

Use imperative mood for instructions. Change 'Understanding trim analysis' to 'Understand trim analysis' to match the guideline that headings should avoid gerunds and use imperative form where appropriate.

[nitpick] The heading 'Fix trim warnings' is inconsistent with line 326 'Understanding trim analysis'. For consistency in the Concepts section, consider using either 'Understand...' or 'Understanding...' for all conceptual topics, and reserve imperative mood ('Fix', 'Prepare') for How-to guides.
| 1. **Try to eliminate reflection** - This is always the best option if possible | ||
| 2. **Use DynamicallyAccessedMembers** - If types are known, make the code trim-compatible | ||
| 3. **Use RequiresUnreferencedCode** - If truly dynamic, document the incompatibility | ||
| 4. **Suppress warnings as last resort** - Only if you're certain the code is safe |

Change imperative 'Try to eliminate' to simple present 'Eliminate reflection'. Per the guidelines, 'Start statements with verbs when possible' and use imperative mood for instructions. Apply to all list items: 'Eliminate reflection', 'Use DynamicallyAccessedMembers', 'Use RequiresUnreferencedCode', 'Suppress warnings as last resort'.
| 1. You've manually ensured all required code is preserved (via `DynamicDependency` or other mechanisms) | ||
| 2. The code path is never executed in trimmed scenarios | ||
| 3. You've thoroughly tested the trimmed application |

Add periods to list items. Per the guidelines, 'End list items with periods if more than three words - THIS IS NON-NEGOTIABLE'. All three items are more than three words and need periods at the end.
| This approach: | ||
| - Makes it clear which specific call is suppressed | ||
| - Prevents accidentally suppressing other warnings if the code changes | ||
| - Keeps the justification close to the suppressed call |

| Ensure you've annotated the entire call chain from the reflection usage back to the source of the `Type`: | ||
|
|
||
| 1. Find where reflection is used (like `GetMethods()`) | ||
| 2. Annotate that method's parameter | ||
| 3. Follow the `Type` value backward through all method calls | ||
| 4. Annotate each parameter, field, or generic type parameter in the chain |

Add periods to list items. Per the guidelines, 'End list items with periods if more than three words - THIS IS NON-NEGOTIABLE'. All four items are more than three words and need periods at the end.
| 1. Start with your own code - fix warnings in code you control first | ||
| 2. Use `TrimmerSingleWarn` to see individual warnings from packages | ||
| 3. Consider if trimming is appropriate for your application | ||
| 4. Check [Known trimming incompatibilities](incompatibilities.md) for framework-level issues |

| Use the narrowest type possible to minimize app size. |

Use imperative mood for instructions. Change 'Use the narrowest type possible to minimize app size' to 'Use the narrowest type possible to minimize app size.' (the period is already there, but the sentence structure should be imperative without 'the' article per guidelines on starting with verbs).
