Is Secure Coding in C# and .NET Still Relevant?

The last update landed September 15, 2026 — and for a Development course, freshness is the first thing to verify. An updated date means the instructor still maintains the material; a stale one means you learn last year's version of the tools.

The 4.5 rating from 926 learners suggests the content holds up in practice — ratings at that level rarely survive contact with outdated material. The entry bar looks low, which makes this a reasonable first course in the topic rather than a capstone.

What the Course Actually Delivers in 8h

The published syllabus lists 10 outcomes — headlined by apply secure coding principles to C# and .NET applications; identify and fix common OWASP Top 10 vulnerabilities in ASP.NET Core apps; secure APIs using authentication, authorization, JWT, roles, claims, and policies. Total runtime is 8h of video, which you work through self-paced with lifetime access.

Is the Price Fair After the Coupon Discount?

The real comparison is not list versus coupon, but coupon versus the next-best course at the same sale price — and on ratings-per-dollar, this one compares well. $149.99 is the list price, but Udemy courses at this level almost never sell at list. This coupon brings it to $9.99 — a 93% cut worth $140.00. Spread over the runtime, that is about $1.25 per hour of instruction — cheaper than a coffee per study session.
