Developers are increasingly relying on AI agents to both build new software as well as extend capabilities of existing projects that they support. One challenge with AI-based systems, however, is that to produce the right output you need to first establish really good context. If you don't decide what you're building and why you're building it ahea...
In the fast-paced world of AI development, connecting intelligent applications to the tools and data sources they need can be challenging. That's why Model Context Protocol (MCP) is resonating with some many, an open standard that's transforming how developers integrate AI capabilities into their applications. MCP enables you to "connect once, int...
In tech, the ground shifts fast—new frameworks, new patterns, new demands. That’s why our developer tools need to move just as quickly. At Microsoft, we’re building tools that keep pace with how you build—whether you’re debugging locally in VS Code, deploying to Azure, or exploring what’s next with AI.

One of our recent initiatives was to rebuild the .NET Framework build system by leveraging AI to automate the process. Here’s the story of how we successfully achieved this transf...
In this blog post, we will provide some guidelines on how to mitigate prompt injection attacks in Model Context Protocol (MCP) and share the steps Microsoft has taken to address emerging risks such as this one for our customers. MCP is an open protocol spearheaded by Anthropic that defines a standardized interface for connecting Large Language M...
Microsoft is collaborating with Anthropic to create an official C# SDK for the Model Context Protocol (MCP). MCP has seen rapid adoption in the AI community, and this partnership aims to enhance the integration of AI models into C# applications. The SDK is being developed as an open-source project in the modelcontextprotocol GitHub organization,...
