How Can I Use OpenTelemetry in.NET to Track a Slow API Request?
Have you ever gotten a bug report stating that an API is responding slowly, but you are unable to identify the cause of the delay? Before providing a response, the request may take some time to run application code, wait for a database query, call another API, or process data. You cannot determine which component…
Using the New ASP.NET Core 11 APIs to Read CBOR Data Incrementally
Applications that exchange structured binary data frequently need to read files, interpret network communications, or interact with external devices. Incremental reading capability is introduced in System by NET 11 RC 2. When the input arrives in several pieces, putting the complete payload into a single buffer before parsing it might add needless memory strain and…
Using Prometheus and Grafana to visualize EF Core Performance
Analyzing raw telemetry streams is challenging without a graphical layer, thus capturing application metrics is just half the fight. You require a centralized monitoring dashboard to watch query volumes, active database contexts, and compilation cache efficiency in order to efficiently monitor Entity Framework Core (EF Core) performance in real time. You may develop a production-grade…
ASP.NET Master Resource-Based Authorization Fundamentals: Ensuring Record Ownership
While Role-Based and Policy-Based authorization evaluate permissions globally or against user claims, many enterprise applications require finer control: Resource-Based Authorization. Resource-based authorization answers the question: Does the currently authenticated user have permission to modify or delete this specific database record? For example, a standard user should be allowed to edit their own blog post or…
.NET 11 speed: Which Enhancements Are Important in Practical Applications?
Benchmark data, runtime modifications, and low-level optimizations are frequently used to demonstrate gains in.NET speed. Although those specifics are helpful, they don’t always address the issue that developers truly deal with: Which performance enhancements in.NET 11 are most likely to be significant in a practical application? The workload determines the response. While a data-processing service…
EF Core N+1 Query Problem: How to Detect, Measure, and Fix
If your EF Core application works perfectly with a small dataset but suddenly slows down as the amount of data grows, don’t immediately blame your API, server, or database hardware. The problem may be much simpler: your application is making too many database queries. One of the most common causes is the N+1 query problem…
Create an ASP.NET Core Web API with SQL Server Stored Procedures and Dapper
In many applications, creating, retrieving, updating, and deleting data requires communication between the API layer and a relational database. Using Dapper and SQL Server Stored Procedures, we will construct a basic ASP.NET Core Web API in this post that carries out CRUD operations on a Department database. A straightforward layered structure is used in the…
Mocking Without the Refactor and Without the Wrapper
When they begin mocking, the majority of.NET test suites encounter the same three obstacles. Ceremony is the first; your test consists of 40% wrapper types. The second is silence: the test succeeds for a reason unrelated to the behavior it purports to examine, the fake answers a call that no one intended it to receive,…
HTTP Connection in.NET 11 Eviction: DNS Failover Testing for Extended APIs
Outbound HTTP calls are made by the majority of ASP.NET Core apps. They could make calls to third-party platforms, cloud services, internal microservices, payment services, and authentication APIs. HttpClient often has a lengthy lifespan and depends on connection pooling for these applications. Reusing connections is a crucial component of effective HTTP communication as it eliminates…
Benchmarking .NET MAUI Startup After CoreCLR Migration
One of the first things consumers notice about a mobile application is its beginning. If users spend several seconds staring at a splash screen before the first interactive panel displays, a feature-rich program might have great functionality but yet seem sluggish. Startup for.NET MAUI apps involves more than just loading the initial page: For .NET…
