VisualBasicCompilation Class

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.

The Compilation object is an immutable representation of a single invocation of the compiler. Although immutable, a Compilation is also on-demand, in that a compilation can be created quickly, but will that compiler parts or all of the code in order to respond to method or properties. Also, a compilation can produce a new compilation with a small change from the current compilation. This is, in many cases, more efficient than creating a new compilation from scratch, as the new compilation can share information from the old compilation.

Built-in operators are commonly created for symbols like `bool int.operator ==(int v1, int v2)` which the language implicitly supports, even if such a symbol is not explicitly defined for that type in either source or metadata. (Inherited from Compilation)
CreateBuiltinOperator(String, ITypeSymbol, ITypeSymbol)	Creates an IMethodSymbol whose MethodKind is BuiltinOperator for a unary operator. Built-in operators are commonly created for symbols like `bool int.operator -(int value)` which the language implicitly supports, even if such a symbol is not explicitly defined for that type in either source or metadata.

EmitDifference(EmitBaseline, IEnumerable<SemanticEdit>, Func<ISymbol,Boolean>, Stream, Stream, Stream, CancellationToken)	Emit the differences between the compilation and the previous generation for Edit and Continue. The differences are expressed as added and changed symbols, and are emitted as metadata, IL, and PDB deltas. A representation of the current compilation is returned as an EmitBaseline for use in a subsequent Edit and Continue. (Inherited from Compilation)
EmitDifference(EmitBaseline, IEnumerable<SemanticEdit>, Func<ISymbol, Boolean>, Stream, Stream, Stream, ICollection<MethodDefinitionHandle>, CancellationToken)	Obsolete. Emit the differences between the compilation and the previous generation for Edit and Continue. The differences are expressed as added and changed symbols, and are emitted as metadata, IL, and PDB deltas. A representation of the current compilation is returned as an EmitBaseline for use in a subsequent Edit and Continue. (Inherited from Compilation)
EmitDifference(EmitBaseline, IEnumerable<SemanticEdit>, Stream, Stream, Stream, ICollection<MethodDefinitionHandle>, CancellationToken)	Obsolete. Emit the differences between the compilation and the previous generation for Edit and Continue. The differences are expressed as added and changed symbols, and are emitted as metadata, IL, and PDB deltas. A representation of the current compilation is returned as an EmitBaseline for use in a subsequent Edit and Continue. (Inherited from Compilation)
GetAssemblyOrModuleSymbol(MetadataReference)	Gets the IAssemblySymbol or IModuleSymbol for a metadata reference used to create this compilation. (Inherited from Compilation)
GetCompilationNamespace(INamespaceSymbol)	Gets the corresponding compilation namespace for the specified module or assembly namespace. (Inherited from Compilation)
GetDeclarationDiagnostics(CancellationToken)	Get declarations diagnostics for the entire compilation. This includes diagnostics from declarations, BUT NOT the bodies of methods or initializers. The set of declaration diagnostics is cached, so calling this method a second time should be fast.
GetDiagnostics(CancellationToken)	Get all diagnostics for the entire compilation. This includes diagnostics from parsing, declarations, and the bodies of methods. Getting all the diagnostics is potentially a length operations, as it requires parsing and compiling all the code. The set of diagnostics is not caches, so each call to this method will recompile all methods.
GetEntryPoint(CancellationToken)	Returns the Main method that will serves as the entry point of the assembly, if it is executable (and not a script). (Inherited from Compilation)
GetMetadataReference(IAssemblySymbol)	Gets the MetadataReference that corresponds to the assembly symbol. (Inherited from Compilation)
GetMethodBodyDiagnostics(CancellationToken)	Get method body diagnostics for the entire compilation. This includes diagnostics only from the bodies of methods and initializers. These diagnostics are NOT cached, so calling this method a second time repeats significant work.
GetParseDiagnostics(CancellationToken)	Get parse diagnostics for the entire compilation. This includes diagnostics from parsing BUT NOT from declarations and the bodies of methods or initializers. The set of parse diagnostics is cached, so calling this method a second time should be fast.
GetSemanticModel(SyntaxTree, Boolean)	Get a fresh SemanticModel. Note that each invocation gets a fresh SemanticModel, each of which has a cache. Therefore, one effectively clears the cache by discarding the SemanticModel.
GetSpecialType(SpecialType)	Get the symbol for the predefined type from the Cor Library referenced by this compilation. (Inherited from Compilation)
GetSymbolsWithName(Func<String,Boolean>, SymbolFilter, CancellationToken)	Return source declaration symbols whose name meets given predicate.
GetSymbolsWithName(String, SymbolFilter, CancellationToken)
GetTypeByMetadataName(String)	Gets the type within the compilation's assembly and all referenced assemblies (other than those that can only be referenced via an extern alias) using its canonical CLR metadata name. This lookup follows the following order: If the type is found in the compilation's assembly, that type is returned. Next, the core library (the library that defines `System.Object` and has no assembly references) is searched. If the type is found there, that type is returned. Finally, all remaining referenced non-extern assemblies are searched. If one and only one type matching the provided metadata name is found, that single type is returned. Accessibility is ignored for this check. (Inherited from Compilation)
GetTypesByMetadataName(String)	Gets all types with the compilation's assembly and all referenced assemblies that have the given canonical CLR metadata name. Accessibility to the current assembly is ignored when searching for matching type names. (Inherited from Compilation)
GetUnreferencedAssemblyIdentities(Diagnostic)	Given a Diagnostic reporting unreferenced AssemblyIdentitys, returns the actual AssemblyIdentity instances that were not referenced. (Inherited from Compilation)
GetUsedAssemblyReferences(CancellationToken)
GetUsedAssemblyReferences(CancellationToken)	Unique metadata assembly references that are considered to be used by this compilation. For example, if a type declared in a referenced assembly is referenced in source code within this compilation, the reference is considered to be used. Etc. The returned set is a subset of references returned by References API. The result is undefined if the compilation contains errors. The effect of imported namespaces on result of this API depends on whether reporting of unused imports is disabled for the compilation. The reporting of unused imports is disabled if DocumentationMode is set to None. When unused imports reporting is disabled, all referenced assemblies containing any types that belong to imported namespaces are included in the result. I.e. considered used. When unused imports reporting is enabled, imported namespaces do not have effect on the result of this API. Therefore, removing assembly references that aren't in the result, could potentially cause error "CS0246: The type or namespace name could not be found (are you missing a using directive or an assembly reference?)" on an unused namespace import. However, that import would be reported by compiler as unused for the compilation on which this API was invoked. In order to avoid the errors, it is recommended to remove unused assembly references and unused imports at the same time. (Inherited from Compilation)
HasImplicitConversion(ITypeSymbol, ITypeSymbol)	Returns true if there is an implicit (C#) or widening (VB) conversion from `fromType` to `toType`. Returns false if either `fromType` or `toType` is null, or if no such conversion exists. (Inherited from Compilation)
IsSymbolAccessibleWithin(ISymbol, ISymbol, ITypeSymbol)	Checks if `symbol` is accessible from within `within`. An optional qualifier of type `throughType` is used to resolve protected access for instance members. All symbols are required to be from this compilation or some assembly referenced (References) by this compilation. `within` is required to be an INamedTypeSymbol or IAssemblySymbol. (Inherited from Compilation)
