Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Allows asking semantic questions about a tree of syntax nodes in a Compilation. Typically, an instance is obtained by a call to GetSemanticModel(SyntaxTree, SemanticModelOptions).

Remarks
An instance of SemanticModel caches local symbols and semantic information. Thus, it is much more efficient to use a single instance of SemanticModel when asking multiple questions about a syntax tree, because information from the first question may be reused. This also means that holding onto an instance of SemanticModel for a long time may keep a significant amount of memory from being garbage collected.
When an answer is a named symbol that is reachable by traversing from the root of the symbol table, (that is, from an AssemblySymbol of the Compilation), that symbol will be returned (i.e. the returned value will be reference-equal to one reachable from the root of the symbol table). Symbols representing entities without names (e.g. array-of-int) may or may not exhibit reference equality. However, some named symbols (such as local variables) are not reachable from the root. These symbols are visible as answers to semantic questions. When the same SemanticModel object is used, the answers exhibit reference-equality.
