Microsoft Orleans grain design involves following guidelines for interfaces, classes, lifecycle, state, sizing, and grain references to ensure scalable applications. Proper grain sizing and state management directly impact system performance.

Preventing deadlocks in Orleans cross-grain communication involves applying concurrency best practices for the single-threaded execution model and configuring reentrancy options. Proper rules for calling patterns and error propagation also help avoid blocking calls.

Serialization in Microsoft Orleans works by applying rules for record types, type aliases, surrogates, immutability, and version tolerance. These guidelines ensure efficient and backward-compatible data transfer across distributed grains.

Use streams in an Orleans application when you need best practices for event distribution and processing. Streams provide a mechanism for passing data between producers and consumers without requiring direct cross-grain coupling.

Microsoft Orleans supports fan-out and aggregation patterns through defined cross-grain communication rules. These calling patterns allow a grain to distribute requests to multiple grains and aggregate the responses efficiently.
