Expands and Reduces subtrees.
Expansion: 1) Makes inferred names explicit (on anonymous types and tuples). 2) Replaces names with fully qualified dotted names. 3) Adds parentheses around expressions 4) Adds explicit casts/conversions where implicit conversions exist 5) Adds escaping to identifiers 6) Rewrites extension method invocations with explicit calls on the class containing the extension method.
Reduction: 1) Shortens dotted names to their minimally qualified form 2) Removes unnecessary parentheses 3) Removes unnecessary casts/conversions 4) Removes unnecessary escaping 5) Rewrites explicit calls to extension methods to use dot notation 6) Removes unnecessary tuple element names and anonymous type member names

Simplifier
Properties
| AddImportsAnnotation |
The annotation Microsoft.CodeAnalysis.CodeActions.CodeAction.CleanupDocumentAsync(Microsoft.CodeAnalysis.Document,Microsoft.CodeAnalysis.CodeCleanup.CodeCleanupOptions,System.Threading.CancellationToken) used to identify sub trees to look for symbol annotations on. It will then add import directives for these symbol annotations. |
| Annotation |
The annotation the reducer uses to identify sub trees to be reduced. The Expand operations add this annotation to nodes so that the Reduce operations later find them. |
| SpecialTypeAnnotation |
This is the annotation used by the simplifier and expander to identify Predefined type and preserving them from over simplification |
Methods
| Expand(SyntaxToken, SemanticModel, Workspace, Func<SyntaxNode,Boolean>, CancellationToken) |
Expand qualifying parts of the specified subtree, annotating the parts using the Annotation annotation. |
| Expand<TNode>(TNode, SemanticModel, Workspace, Func<SyntaxNode,Boolean>, Boolean, CancellationToken) |
Expand qualifying parts of the specified subtree, annotating the parts using the Annotation annotation. |
| ExpandAsync(SyntaxToken, Document, Func<SyntaxNode,Boolean>, CancellationToken) |
Expand qualifying parts of the specified subtree, annotating the parts using the Annotation annotation. |
| ExpandAsync<TNode>(TNode, Document, Func<SyntaxNode,Boolean>, Boolean, CancellationToken) |
Expand qualifying parts of the specified subtree, annotating the parts using the Annotation annotation. |
| ReduceAsync(Document, IEnumerable<TextSpan>, OptionSet, CancellationToken) |
Reduce the sub-trees annotated with Annotation found within the specified spans. The annotated node and all child nodes will be reduced. |
| ReduceAsync(Document, OptionSet, CancellationToken) |
Reduce all sub-trees annotated with Annotation found within the document. The annotated node and all child nodes will be reduced. |
| ReduceAsync(Document, SyntaxAnnotation, OptionSet, CancellationToken) |
Reduce the sub-trees annotated with Annotation found within the subtrees identified with the specified |
| ReduceAsync(Document, TextSpan, OptionSet, CancellationToken) |
Reduce the sub-trees annotated with Annotation found within the specified span. The annotated node and all child nodes will be reduced. |
