## Example Manifest Structure

```xml
<?xml version="1.0" encoding="utf-8" ?>
<manifest>
  <control namespace="SampleNamespace" 
           constructor="SampleControl" 
           version="1.0.0" 
           display-name-key="Sample_Display_Key" 
           description-key="Sample_Desc_Key" 
           control-type="standard">
    
    <!-- Properties -->
    <property name="sampleProperty" 
              display-name-key="Property_Display_Key" 
              description-key="Property_Desc_Key" 
              of-type="SingleLine.Text" 
              usage="bound" 
              required="true" />
    
    <!-- Type Group Example -->
    <type-group name="numbers">
      <type>Whole.None</type>
      <type>Currency</type>
      <type>FP</type>
      <type>Decimal</type>
    </type-group>
    
    <property name="numericProperty"
              display-name-key="Numeric_Display_Key"
              of-type-group="numbers"
              usage="bound" />
    
    <!-- Data Set Example -->
    <data-set name="dataSetProperty" 
              display-name-key="Dataset_Display_Key">
    </data-set>
    
    <!-- Events -->
    <event name="onCustomEvent"
           display-name-key="Event_Display_Key"
           description-key="Event_Desc_Key" />
    
    <!-- Resources -->
    <resources>
      <code path="index.ts" order="1" />
      <css path="css/SampleControl.css" order="1" />
      <img path="img/icon.png" />
      <resx path="strings/SampleControl.1033.resx" version="1.0.0" />
    </resources>
    
    <!-- Feature Usage -->
    <feature-usage>
      <uses-feature name="WebAPI" required="true" />
      <uses-feature name="Device.captureImage" required="false" />
    </feature-usage>
    
    <!-- Platform Library -->
    <platform-library name="React" version="16.8.6" />
    <platform-library name="Fluent" version="8.29.0" />
    
  </control>
</manifest>
```

## Manifest Validation

The manifest schema is validated during the build process:
- Missing required elements will cause build errors
- Invalid attribute values will be flagged
- Use `pac pcf` commands to validate manifest structure

## Best Practices

1. **Semantic Versioning**: Use semantic versioning (major.minor.patch) for component versions
2. **Localization Keys**: Always use resource keys instead of hardcoded strings
3. **Feature Declaration**: Declare all features your component uses
4. **Required vs Optional**: Mark properties and features as required only when truly necessary
5. **Type Groups**: Use type-groups for properties that accept multiple numeric types
6. **Data Types**: Choose the most specific data type that matches your requirements
7. **CSS Scoping**: Scope CSS to avoid conflicts with host applications
8. **Resource Organization**: Keep resources organized in separate folders (css/, img/, strings/)

## Data Type Reference

Common `of-type` values for properties:

- **Text**: SingleLine.Text, Multiple, SingleLine.TextArea, SingleLine.Email, SingleLine.Phone, SingleLine.Url, SingleLine.Ticker
- **Numbers**: Whole.None, Currency, FP, Decimal
- **Date/Time**: DateAndTime.DateAndTime, DateAndTime.DateOnly
- **Boolean**: TwoOptions
- **Lookup**: Lookup.Simple
- **OptionSet**: OptionSet, MultiSelectOptionSet
- **Other**: Enum

## Platform Availability Legend

- ✅ **Model-driven apps**: Fully supported
- ✅ **Canvas apps**: Supported (may have limitations)
- ✅ **Portals**: Supported in Power Pages

Most manifest elements are available across all platforms, but some features (like certain Device APIs or platform actions) may be platform-specific. Always test in your target environment.
