Class TransformerContext

Context passed to a source transformer when Execute(TransformerContext) is called. The implementation can modify the compilation using the methods AddSyntaxTrees(SyntaxTree[]), ReplaceSyntaxTree(SyntaxTree, SyntaxTree) or AddResources(ManagedResource[]). It can report a diagnostic using ReportDiagnostic(Diagnostic) or suppress diagnostics using RegisterDiagnosticFilter(SuppressionDescriptor, Action<DiagnosticFilteringRequest>).
