Abstract: A workspace model generates a component of a solution from an immutable object representing the solution at a given point in time. A component may be requested by an extension to an integrated development environment for the extension's use. The workspace model determines a sequence of operations needed to construct the requested component at the time the component is requested using the state of the solution represented through the immutable object. The immutable object allows the extension to access the requested component while the integrated development environment is used to alter the solution.

Abstract: An augmented parser can create an augmented parse tree that captures all the information in the source code as additional elements. Information included in the augmented parse tree can include whitespace, comments, pre-processor directives, line continuation characters, missing text, text errors, and original text. Thus, the augmented parse tree can be used to fully reconstruct the original source code, character for character, including spaces, comments, and incorrect code. The improved parser can store syntactic error information in the original source code in the parse tree. The augmented parse tree can be used to generate or modify source code. The parse tree created by the augmented parser can be used for incremental parsing to create a new augmented parse tree after a change.

Abstract: A system and method for providing a completion list associated with computer program source code and a dynamic expression. A static analysis is performed to find and aggregate one or more candidate types of the expression. The analysis may include one or more of a number of techniques, including analyzing expressions that are assigned to a program variable, following method calls, examining system or other specified assemblies, loading runtime assemblies, or making inferences based on other uses of the variable. A dynamic analysis may be performed and combined with a static analysis. A completion list may be filtered or ordered based on a configured criteria.

Abstract: A system and method for providing a completion list associated with computer program source code and a dynamic expression. A dynamic analysis is performed to find and aggregate one or more candidate types of the expression. During an execution of the target program, a runtime monitor tracks events that may indicate a type of program variables. The analysis may include one or more of a number of static analysis techniques, including analyzing expressions that are assigned to a program variable, following method calls, examining system or other specified assemblies, loading runtime assemblies, or making inferences based on other uses of the variable.
