  • Flexible base class library
    Patent number: 8271938
    Abstract: Mechanisms that allow frameworks significant flexibility in varying the library of common base classes in a manner that better suits the domain of applications served by the framework. Instead of providing the base class library, the runtime provides a data contract for the data structure of each base class. The frameworks can then define each base class in a custom way so long as the data contract is honored. Thus, for example, the framework may provide custom framework-specific methods and/or properties as is appropriate for the framework. Another framework might define the base classes in a different way.

  • Handling multiple definition of types
    Patent number: 8201155
    Abstract: User assemblies can be created by a compiler that can handle more than one type definition during execution. Local copies are created for respective authoritative types in a code library, and the local copies are marked with a local type identifier. An authoritative type identifier (e.g., a globally unique identifier (GUID)) is copied from the authoritative type to the local type, and functions and properties associated with the local type are also copied from the authoritative type. Authoritative types are resolved for requested types when a local assembly references a local type from a compiled user assembly. The local type can be identified by a local type identifier, and an authoritative type can be retrieved from the code library that has a same authoritative type identifier as the requested type. A local copy of the retrieved authoritative type can be copied to the local assembly under compilation. The compiler can then emit user assemblies that comprise merely local types.

  • PRE-COMPILING HOSTED MANAGED CODE
    Publication number: 20110307858
    Abstract: A hosted pre-compilation system is described herein that provides a way to enable ahead-of-time compilation for managed code running inside a host. The host triggers ahead-of-time compilation at application runtime, after any configuration settings are available. The host can choose which modules to compile, when to compile them, and where to persist the generated images. Upon detecting a module load, the host can trigger pre-compilation, provide the loader an existing pre-compiled image of the module, or do nothing. The runtime/platform validates the integrity of any host-supplied pre-compiled image and provides application programming interfaces (APIs) to inform the host when an image becomes invalid and fails to load. The platform also provides APIs to let the host trigger compilation of binaries at any time relevant to the host, and to generate the images either synchronously or in a background process.

  • Library Conformity Checker
    Publication number: 20110302564
    Abstract: A library management system may compare contracts between programming libraries to identify unions, intersections, and differences between libraries. The management system may have a contract analyzer that may remove the contract definition from an existing library to form a library contract. The library contract may be managed as a first class item within a programming environment, and may be used as a reference for comparing existing and new versions of the library. The library management system may create reference libraries for programmers to write applications using two or more intersecting libraries, among other uses.

  • Application security model
    Patent number: 8011008
    Abstract: Performing security sensitive operations with an application security model. Security agnostic code is executed. The security agnostic code is identified as not having authorization to perform a security sensitive operation. Executing the security agnostic code includes calling code identified as security safe critical code. In response to the security agnostic code calling the security safe critical code, the security safe critical code is executed. The security safe critical code includes functionality for performing validity checks. Executing the security safe critical code includes performing an validity check for the security agnostic code. When the security agnostic code passes the validity check, code identified as security critical code is called. In response to the security safe critical code calling the security critical code, the security critical code is executed. The security critical code is authorized to perform the security sensitive operation.

  • Execution context infrastructure
    Patent number: 7930687
    Abstract: Described herein is an implementation for exposing an “execution context” to a logical execution flow of procedures as it executes. An “execution context” is a set of data and/or sub-procedures that might be useful at some point during a logical execution flow (to manage and control the execution flow and provide additional services to the execution flow) of computer-executable instructions though the often complex, intertwined, and interconnected conglomeration of procedures of software product(s).

  • Using security-related attributes
    Patent number: 7926105
    Abstract: Described is a technology including an evaluation methodology by which a set of privileged code such as a platform's API method may be marked as being security critical and/or safe for being called by untrusted code. The set of code is evaluated to determine whether the code is security critical code, and if so, it is identified as security critical. Such code is further evaluated to determine whether the code is safe with respect to being called by untrusted code, and if so, is marked as safe. To determine whether the code is safe, a determination is made as to whether the first set of code leaks criticality, including by evaluating one or more code paths corresponding to one or more callers of the first set of code, and by evaluating one or more code paths corresponding to one or more callees of the first set of code.

  • System and method providing inlined stub
    Patent number: 7680762
    Abstract: A system and method is provided to facilitate communications between object systems. A caller is provided having optimized in-lined functionality when initiating a remote function call between managed and unmanaged object systems, for example. The in-lined functionality includes utilizing direct calls and returns within a calling function. In this manner, pushing additional arguments onto an execution stack because of an external stub reference is mitigated. In addition, one or more code loops can be analyzed to enable stack markers to be “hoisted” and thus pushed a single time instead of each time the calling function executes. Other aspects of the optimized caller provide garbage collection and thread management, security attribute checking on outgoing calls, calling convention considerations, wherein arguments and return values are organized according to the convention utilized by the remote object system, and in-lined marshalling to provide enhanced performance over external stub code references.

  • Transparent and sub-classable proxies
    Patent number: 7647597
    Abstract: A system and method for interacting with an object is provided. The system includes a method call interceptor that intercepts a method call made on an object and that routes the method call to a proxy. The method call interceptor is accessible to application code. The system also includes an application code generic proxy that after overriding a base class invocation method can receive intercepted method calls, can invoke methods on the object that the proxy images, can receive results from the object that the proxy images and can pass results to the entity that generated the intercepted method call.

  • UNIFIED METADATA FOR EXTERNAL COMPONENTS
    Publication number: 20090319554
    Abstract: A system and method for facilitating execution of multiple assemblies in a framework, in which the assemblies use a component external to the framework, is provided. A runtime manager may retrieve metadata from each of the assemblies, and selectively insert the metadata into a unified types object, so that metadata corresponding to equivalent type definitions is shared. When each assembly is executed, the combined metadata may be used to invoke or otherwise interact with the external component.

  • Managed code type equivalence
    Publication number: 20090319991
    Abstract: The determination of whether two managed code types are of equivalent types on the basis of a comparison between type identifiers of the managed types. The type identifiers may be independent of an assembly in which the managed types are created, a namespace of the corresponding managed type, or a name of the corresponding managed type. Accordingly, the type equivalence determination may be made to be quite flexible, thereby potentially resulting in better type equivalence determinations in of managed types.
