Technical guides, tools and lessons learned around ASP.NET Core, Blazor and software architecture, straight from our project work.
Overview
Practical write-ups on ASP.NET Core, Blazor, .NET migrations and architecture, straight from delivery work at BitSpire, written by Microsoft MVPs based in Switzerland.
How the framework behaves once real traffic, real databases and real deadlines are involved.
.NET Framework 4.8.1 has no end-of-support date of its own, it follows the Windows lifecycle. Why the deadline that actually hits your project comes much earlier, and what that means for your migration.
Read the .NET lifecycle analysisAsNoTracking is not automatically faster: it also drops identity resolution. Three real BenchmarkDotNet scenarios against a SQLite in-memory database show exactly when AsNoTracking wins, when AsNoTrackingWithIdentityResolution wins instead, and why.
Read the AsNoTracking benchmarkHow ASP.NET Core notices aborted HTTP requests and propagates the cancellation through EF Core down to SQL Server, and how architecture tests make sure no action forgets it.
