Abstract: Just in time compiled code and other data within a runtime environment may be shared between multiple applications by identifying common data objects and allowing two or more applications to access the data objects. While at least one application is accessing the objects, the objects may remain in memory. When all applications have stopped accessing an object, the object may be removed from memory. One embodiment may use a server process to manage various operations to facilitate sharing between various applications, such as identifying objects that may be removed from memory and adding newly created data to a database of sharable data.

Abstract: Through one or more transaction calls, an application domain manager enables a host application to create, initialize, customize, and otherwise manage an isolation construct within the application.

Abstract: Systems and methods for enhanced runtime hosting are described. In one aspect the runtime hosting interface includes a host abstraction interface. The HAI allowing the runtime to configure host execution environment parameters and/or notify the host of a runtime event. In particular, the host abstraction interface (HAI) corresponds to execution environment abstractions supported by a host application. Responsive to an action or event, the runtime invokes an identified HAI or an associated object during execution of runtime managed code.

Abstract: Systems and methods for enhanced runtime hosting are described. In one respect, the runtime identifies any abstraction interface(s) exposed by a host application. The abstraction interface(s) correspond to respective execution environment functionality implemented by the hosting application. During execution of runtime managed code and responsive to an action or event associated with an identified one of the respective execution environment abstractions, the runtime calls a specific interface or object corresponding to a specific one of the abstraction interface(s). This allows the host application to customize/enhance its execution environment, which includes the runtime, as a function of the implemented abstraction(s).

Abstract: A system and method is provided for providing security to components or assemblies employed by application programs during runtime. Assemblies carry version information that can be used to enforce the versioning rules described by the application program. At runtime, version numbers requested by the application programs are compared with those version numbers of the assemblies that are actually found. In addition to comparing version numbers, the present invention offers a stricter form of version checking based on cryptographic hashes. An assembly is provided with module information that contains a list of the files that make up the assembly. Part of the information recorded about each module is a hash of the module's contents at the time the manifest was built. An assembly referencing another assembly computes the hash of the manifest of the referenced assembly. An assembly manifest may include dependency information, which is information about other assemblies that the assembly depends on or references.

Abstract: A system and method is provided for providing security to components or assemblies employed by application programs during runtime. The present invention employs digital signature keys to ensure that an assembly name that is published is unique because the assembly is published with a publisher's public key. This prevents others from publishing an updated version of an assembly that claims to be published from the same publisher. The present invention guarantees name uniqueness and prevents name spoofing because the original publisher is the only one with the private key matching the public key related to a published assembly. Due to the fact that the public keys are stored in each reference, the caller can be assured that the assembly that the caller is binding to at runtime comes from the same publisher that owns the private key.
