Three sequence interfaces, three execution models. Use IQueryable when a database can translate the query, IAsyncEnumerable when the producer is async and you want to stream, IEnumerable for everything else in memory.

Pick minimal APIs by default in ASP.NET Core 11. Use controllers only when you need MVC features that minimal APIs still do not match: convention-based routing across many actions, MVC-style filters, or Razor views.

async Task is the default and async void is the exception. Use async void only for event handlers, top-level message-loop handlers, and a handful of framework callbacks that demand a void signature. Everywhere else, async Task wins on exceptions, composition, and testability.

For bulk inserts in .NET 11, neither EF Core nor Dapper wins. SqlBulkCopy does. This is the benchmark, the why, and the seat each tool deserves.

Cursor's Apply silently cancels on big files because the Fast Apply model has an implicit size ceiling. Shrink the edit scope, clean git state, or fall back to a unified diff. Six ranked fixes for Cursor 3.3.

NuGet Package Pruning shipped on-by-default for net10.0 projects, cutting transitive vulnerability reports by 70% and restore times by up to 50%.

Why Claude Code shows 'MCP server disconnected' or 'Connection closed' for a working MCP server when launched from WSL2. Covers stdio spawning across the Windows/Linux boundary, npx and node ENOENT, mirrored networking for HTTP servers, VMMem reaping, and how to diagnose the right one with claude --debug.

After upgrading to C# 14 / .NET 10, calls like array.Contains, x.Reverse(), and MemoryMarshal.Cast suddenly bind to different overloads or stop compiling. Here is what changed and how to pin the old behaviour where it matters.
