Guide Shows How to Build Secure REST APIs with ASP.NET Core and SQL Server

·1 views

A backend development tutorial published on DEV Community walks developers through building a secure RESTful API using ASP.NET Core Web API connected to a SQL Server database. The guide covers configuring database connection strings via environment variables, supporting both Windows Integrated Security and standard SQL Server Authentication. It demonstrates defining a loosely coupled service contract using an asynchronous interface with standard CRUD operations. The core implementation uses native asynchronous ADO.NET extensions to execute stored procedures and efficiently read data streams. The tutorial targets developers looking to structure scalable, maintainable backend services with clean separation of concerns.

How QA Leaders Can Calculate True ROI of AI-Powered Test Automation

A new framework aimed at QA leaders argues that traditional ROI formulas designed for scripted automation tools like Selenium fail to capture the full value of modern AI-powered testing platforms. The guide highlights that AI-native testing introduces distinct cost and benefit structures, including self-healing scripts, agentic test generation, and intelligent failure triage, which older calculations overlook. One key gap identified is maintenance: industry data suggests 30–40% of automation engineering time is spent maintaining existing scripts, a burden that AI self-healing capabilities can significantly reduce. Unlike conventional automation, which delivers static returns, AI testing systems are said to improve over time by learning from execution history and defect patterns, producing compounding rather than linear value. The framework proposes measuring returns across four categories to help QA teams build business cases that resonate with both finance and engineering leadership.

Vulnerability Exploitation Now Top Attack Vector as Patch Times Worsen in 2026

A record 48,185 CVEs were published in 2025, a 20.6% increase over the prior year, while the median time to patch vulnerabilities rose 34% to 43 days. Verizon's 2026 Data Breach Investigations Report found that vulnerability exploitation surpassed credential abuse to become the most common initial attack method for the first time in the report's 19-year history. To address this, security experts recommend formalizing vulnerability remediation SLAs that set strict, severity-based patching deadlines — with critical flaws requiring fixes within 14 days. CISA's new federal directive, BOD 26-04, moves beyond simple CVSS scoring by requiring agencies to assess asset exposure and other contextual risk factors, with full compliance expected by December 7, 2026. Although the directive applies only to federal civilian agencies, CISA has urged private organizations to adopt similar frameworks, and cyber insurers and auditors are already following suit.

A Structured Roadmap for Aspiring Software Architects: What to Learn and When

Becoming a software architect requires mastering a broad range of skills beyond writing code, including system design, security, cloud platforms, and DevOps. Experts recommend following a layered learning path that begins with proficiency in one programming language and strong computer science fundamentals before advancing to backend development, API design, and databases. Aspiring architects should then build knowledge of cloud platforms such as AWS, containerization tools like Docker, and CI/CD pipelines to understand how software reaches production. Architecture-specific skills such as system design patterns, application security, monitoring, and technical documentation round out the roadmap. The emphasis is on knowing when to apply each concept rather than memorizing tools or frameworks in isolation.

Why Most Indie Hacker Launches Fail and What to Do Before Launch Day

Most indie hacker product launches fail not because of poor execution on launch day, but due to inadequate preparation in the months beforehand. Building in public is widely recommended but primarily attracts fellow founders rather than actual paying customers, creating misleading momentum. Founders are advised to identify where their real target buyers spend time — niche forums, Slack groups, or industry newsletters — and build an audience there instead. Positioning is highlighted as a critical pre-launch step, framed not as a tagline exercise but as a clear answer to who the product is for and why they should change their current behavior. One B2B founder's sign-ups jumped from four to twenty-three per week simply by rewriting copy to emphasize the cost of inaction rather than listing product features.
