⚡️ .NET API under 1 million requests per minute
The article discusses the construction of a high-load system based on ASP.NET Core Minimal API using a set of practices for the development of high-load services: EF Core optimization, the use of Dapper, the configuration of PostgreSQL indexes, the implementation of pagination and caching.
The performance of the solutions is evaluated using BenchmarkDotNet on a demo project that includes the Orders.Api service and the Orders.Benchmark benchmark set.

⚡️ Memory in C# will become noticeably safer
Microsoft has announced a large-scale rethinking of the memory safety model in C#. The key change is that unsafe will no longer be just a pointer marker and will become an explicit contract between the author of the code and its consumers, and the compiler will begin to control potentially harmful memory operations more strictly. Innovations should reduce the number of security errors and make the code, especially created with the help of AI tools, more reliable and predictable.

Improving C# Memory Safety
The `unsafe` keyword is being redesigned to mark caller-facing contracts rather than just syntax. Safety obligations between callers and callees become visible and reviewable. The model is motivated by the rise of AI-assisted code generation and arrives as…

⚡️ HybridCache is a single API for two-tier caching
HybridCache is an API that combines fast local IMemoryCache and distributed IDistributedCache, such as Redis.
HybridCache automatically works with two cache tiers, takes care of data serialization, and protects applications from cache stampede, a situation where many concurrent requests overload the database after the cache has expired.
HybridCache also supports invalidation by keys and tags, but retains an important limitation: local caches on other servers are not cleared instantly, so developers need to configure the L1 cache lifetime separately.

⚡️ How to Create an MCP Server on .NET
Paul Michaels showed how to turn an ordinary . NET code into a set of tools that can be used by AI assistants like Cursor, VS Code, and LM Studio.
His sample MCP server connects to a local LLM through LM Studio, finds available functions in the assembly and allows the agent to call them via stdin/stdout — for example, create or add files.
According to the author, the basic implementation takes about 12 lines of code, and the new AI tool can be described as a simple static method with attributes and a clear text description.

⚡️ .NET 11: Runtime Async, Native AOT, and AI Application Development Tools
At the Microsoft Build 2026 conference, the company spoke in detail about the key innovations of .NET 11.
The update includes an accelerated SDK with support for Native AOT, new capabilities for working with AI agents, improvements to System.Text.Json, and built-in support for the JSON Lines format.
One of the main announcements was Runtime Async, a new asynchronous execution mechanism that improves performance, reduces the size of applications, and simplifies debugging.
Microsoft also unveiled an initiative to improve memory security and a number of runtime optimizations that should make .NET a more efficient platform for cloud-native and AI-centric applications.
