    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.

    摘要翻译： 使用扩展方法扩展现有类型，包括构造和密封类型的体系结构。 扩展方法是可以使用实例方法语法调用的静态方法。 扩展方法通过在方法的第一个参数上指定关键字“this”作为修饰符来声明。 扩展方法具有常规静态方法的所有功能。 另外，一旦导入，可以使用实例方法语法来调用扩展方法。 还公开了导入扩展方法和扩展方法调用的规则。 扩展方法通过using-namespace-directives导入。 除了导入命名空间中包含的类型之外，using-namespace-directive会在命名空间中的所有静态类中导入所有扩展方法。 实际上，导入的扩展方法在其第一个参数给出的类型上显示为附加方法，并且具有比常规实例方法更低的优先级。

    摘要： The utilization of data services (such as web services) may involve the invocation of services, which may reduce performance and overburden the server. In some scenarios, the invocation may be specified in a language that does not support batch invocation, but it may not be feasible to re-code the invocations in a language that supports batching. Instead, the service invocations may be automatically translated into a batch logic specified in a batch-capable language and sent to the service as a batch. For example, a local proxy may receive a language-integrated query having two or more service invocations, compile the query into an expression tree including the two or more invocations, and send the expression tree to the service host to achieve the batch processing of the service invocations.

    摘要翻译： 数据服务（如Web服务）的使用可能涉及服务的调用，这可能会降低服务器的性能和负担。 在某些情况下，可以使用不支持批量调用的语言来指定调用，但以支持批处理的语言重新编码调用可能不可行。 相反，服务调用可以自动转换为以批处理语言指定的批处理逻辑，并作为批处理发送到服务。 例如，本地代理可以接收具有两个或多个服务调用的语言集成查询，将查询编译成包括两个或更多个调用的表达式树，并将表达式树发送到服务主机以实现批处理 服务调用。

    摘要： Queries against data sources (such as language-integrated queries to be applied against relational databases) may be prepared for processing by a query processing pipeline. This pipeline performs services including transforming the query into a form more easily applied by the data source, e.g., into SQL, by matching query terms with query operators configured to handle various query operations. Many query processing pipelines include single-item query operators that perform individual operations (e.g., an updating query operator that specifies an updating of individual records of a table.) An integrated query pipeline may be devised that includes both single-item query operators and multiple-item query operators that specify operations on sets of data items. An integrated query processing pipeline may analyze the query to determine whether a single-item or multiple-item operation is specified in order to select an appropriate query operator, which may improve the efficiency and performance of the data source querying.

    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： 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.
