The present concepts relate to erasing the delay effects caused by latency. A server may model an environment. The server may transmit a series of state information relating to the state of the environment to a client. The client may receive an input provided by a user. In response, the client may transmit the input along with the state information to the server, where the state information corresponds to the state of the environment from the user's perspective at the time the user provided the input. The server may process the input according to the state information received with the input rather than the state of the environment being modeled by the server at the time the input is received by the server. Accordingly, the user may experience that the server is responsive to her inputs as though there were no latency.

Latency erasure

Embodiments are directed to dynamically adapting metadata for use with a native data encoding and to efficiently modifying object model type references. In one scenario, a computer system instantiates a metadata reader over an object model description to access various portions of metadata in the object model description. The metadata reader is configured to read native metadata, where native metadata is metadata represented in an encoding that is expected by the metadata reader. The metadata reader determines that the accessed metadata is encoded in a non-native encoding and then determines which metadata modifications are to be performed to transform the non-native encoding into a native encoding. The computer system then dynamically adapts the metadata of the object model from a non-native encoding to a native encoding according to the determined modifications. As such, the object model is readable by a native runtime.

Efficiently providing multiple metadata representations of the same type

Embodiments are directed to providing a simulation of a type-level construct on an interface instance and to maintaining a token-based event handling system. In one scenario, a computer system instantiates an interface instance that includes an instance object and multiple instance members. The computer system also instantiates a separate typed object which is configured to maintain one or more simulated type-level parameterized constructors. The computer system then associates the instantiated interface instance with the separate typed object. The typed object routes method invocations from the interface instance to various simulated type-level parameterized constructors and static members of the type.

The present invention extends to methods, systems, and computer program products for updating signature algorithms used for signing an assembly with a strong name without changing the identity of the assembly. The present invention enables an assembly that has already been given an identity (via strong name signing with an identity public/private key pair) to be resigned with a different public/private key pair without changing the original identity that was based on the identity public/private key pair. This is accomplished by including a counter signature within the assembly that links the original identity of the assembly to the new signature key pair.

Updating signature algorithms for strong name binding

Various technologies and techniques are disclosed that use code access security for providing runtime accessibility checks. A request is received from a first program to access at least one private member of a second program at runtime. If the first program has a greater than or equal security context than the second program, then the first program is granted access to the at least one private member of the second program. This code access security check can be provided in a framework environment that is responsible for managing programs that are from unknown or untrusted sources.
