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.

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.

Methods and systems are provided for expressing one or more associations between source language declarations and implementations in a language neutral fashion. A determination is made as to whether a source language association rule related to a declaration is different from a default association rule for a target runtime. If so, an override association is expressed between the declaration and the implementation, and if not, a default association is expressed. Methods and systems are also provided for interpreting an association between a declaration and an implementation in a runtime system, wherein a determination is made as to whether the association comprises an override association. If so, the association is interpreted according to an override association rule for the runtime system, and if not, the association is interpreted according to a default association rule.

Performing validation of a derived virtual method includes receiving program code where the derived virtual method is derived from a virtual method of the program language used to generate the program code, compiling the program code to an intermediate language expression, generating metadata descriptive of the compiled program code, validating the use of the derived virtual method by accessing the metadata, and permitting the use of the derived virtual method if the metadata grants override permissions concerning the virtual method of the programming language. The metadata indicating access and override permissions may be generated while compiling the program code in the common language infrastructure. Alternately, the flag may use pre-existing values indicative of the access and override permissions concerning the virtual method of the programming language.
