What are AI SDKs for C#?

AI SDKs (Software Development Kits) are collections of tools, libraries, APIs, and documentation that help developers build, integrate, and deploy artificial intelligence capabilities into applications and systems. These SDKs provide prebuilt components for tasks such as natural language processing, computer vision, speech recognition, generative AI, model inference, and agent orchestration, reducing the complexity of AI development. Many AI SDKs support multiple programming languages, cloud platforms, and frameworks, enabling developers to accelerate experimentation and production deployment. They often include testing tools, authentication, monitoring, and integration support for connecting AI models with enterprise applications, databases, and external services. By simplifying access to AI functionality and infrastructure, AI SDKs help developers build intelligent applications faster, more reliably, and at scale.

    Google GenAI SDK
    The Gemini API libraries provide official, production-ready Google GenAI SDKs for building with the Gemini API in popular programming languages. Google recommends using the Google GenAI SDK when building with Gemini, since these libraries are developed and maintained by Google, used across official documentation and examples, and are generally available for production use. The SDKs are available for Python, JavaScript/TypeScript, Go, Java, and C#, with installation through standard package managers such as pip install google-genai, npm install google/genai, Maven dependencies for google genai, and dotnet add package Google GenAI. They provide access to the latest Gemini API features and are designed to offer the best performance when working with Gemini models. Google strongly recommends migrating from legacy libraries to the new Google GenAI SDK because the legacy libraries are not actively maintained.
