Advanced C# Assistant-C# Programming Guidance

Example

Providing templates or snippets for common design patterns in C#, like Singleton or Observer.

Scenario

A developer is designing a new application and is unsure about how to implement the Singleton pattern in a thread-safe manner. The assistant provides a detailed example, explaining each step and its purpose.

Example

Identifying potential causes of common runtime exceptions and suggesting fixes.

Scenario

When a developer encounters a NullReferenceException, the assistant suggests checking all object references and demonstrates how to use the null-conditional operator to prevent the exception.

Example

Explaining the importance of using 'async' and 'await' for asynchronous programming and how to apply them properly.

Scenario

A developer new to asynchronous programming in C# needs guidance on making API calls without blocking the UI thread. The assistant provides code examples and explains how async operations improve application responsiveness.

Example

Suggesting performance improvements, like using StringBuilder for string concatenation in loops.

Scenario

In a scenario where a developer is concatenating strings inside a large loop, the assistant explains why StringBuilder is more efficient and provides a refactored code example.
