摘要： A compiler supporting a language in which selected semantic objects are represented as data objects. The data objects may be used in multiple ways to expand the capabilities of the programming language. Data objects may be passed to applications and used to create executable instructions for that application. In this way, instructions written in the native language of the compiler may be used to control applications that accept programs in a language inconsistent with the native language of the compiler. The syntax checking and variable binding capabilities of the compiler may be used for those instructions that will be executed by an application separate from the object code generated by the compiler. The semantic objects represented as data objects may be selected based on express operations included in the source code or may be based on implicit type conversion.

摘要： Architecture that extends existing types including constructed and sealed types using extension methods. Extension methods are static methods that can be invoked using instance method syntax. Extension methods are declared by specifying the keyword “this” as a modifier on the first parameter of the methods. Extension methods have all the capabilities of regular static methods. In addition, once imported, extension methods can be invoked using instance method syntax. Also disclosed are rules for importing extension methods, and extension method invocations. Extension methods are imported through using-namespace-directives. In addition to importing the types contained in a namespace, a using-namespace-directive imports all extension methods in all static classes in the namespace. In effect, imported extension methods appear as additional methods on the types that are given by their first parameter and have lower precedence than regular instance methods.

摘要： A program execution engine that facilitates generic type variance verification is provided. The execution engine receives a program executable in the form of intermediate language (IL). The program executable can be based on code that includes expression(s) with generic type(s) which have been identified as requiring variance verification (e.g., covariance and/or contra-variance). The execution engine includes a variance verification component that dynamically determines whether value(s) associated with the generic type(s) identified as requiring variance verification comply with the particular variance verification requirement. The variance verification component can provide error information (e.g., throw an exception), if the specified variance is not safely compliant. Variance verification can be based on static checking which places the burden on a source language compiler to emit the run-time checks in intermediate language (IL), if run-time checked variance is required. Additionally, language(s) that do not support variance can treat generic type(s) as non-variant.

摘要翻译： 提供了促进通用类型方差验证的程序执行引擎。 执行引擎以中间语言（IL）的形式接收可执行的程序。 程序可执行程序可以基于包括已经被识别为需要方差验证（例如协方差和/或反差）的通用类型的表达式的代码。 执行引擎包括方差验证组件，其动态地确定与被识别为需要方差验证的通用类型相关联的值是否符合特定方差验证要求。 方差验证组件可以提供错误信息（例如，抛出异常），如果指定的方差不能安全地符合。 方差验证可以基于静态检查，如果需要运行时检查方差，那么将源语言编译器的负担放在中间语言（IL）中发出运行时检查。 另外，不支持差异的语言可以将通用类型视为非变体。

摘要： An active debugging environment for debugging a virtual application that contains program language code from multiple compiled and/or interpreted programming languages. The active debugging environment is language neutral and host neutral, where the host is a standard content centric script host with language engines for each of the multiple compiled and/or interpreted programming languages represented in the virtual application. The active debugging environment user interface can be of any debug tool interface design. The language neutral and host neutral active debugging environment is facilitated by a process debug manager that catalogs and manages application specific components, and a machine debug manager that catalogs and manages the various applications that comprise a virtual application being run by the script host. The process debug manager and the machine debug manager act as an interface between the language engine specific programming language details and the debug user interface.
