Unlike .NET v3 and v3.5 which were essentially extensions to v2. .NET4 is an entirely self contained brand spanking new (and much lighter) framework. As such you will need to change your application pool like so:Go to IIS and find the Application Pool you are using. Right click it and select Basic Settings then simply change the target framework to .NET Framework v4 as illustrated.

ReplyDeleteRunning into the error "Unrecognized attribute 'targetFramework'" while upgrading to .NET 4 can be frustrating, especially when you’re expecting a smooth transition. It usually points to mismatches in configuration files or the environment setup — a small detail, but one that can stop everything from working correctly. This situation reminds me a bit of trying to ดูซีรี่ย์ Netflix with a bad internet connection. You’re excited to see what happens next, but a small technical issue can freeze the whole experience. Just like Netflix streaming needs the right settings and bandwidth, .NET upgrades require compatible configurations and attention to detail. In both cases, fixing the issue brings satisfaction — and lets you get back to what matters, whether it's coding or binge-watching your favorite show.
ReplyDeleteIt feels just like when you're trying to watch free movies online ดูหนังฟรี — you find a promising website, but then something goes wrong: broken links, missing subtitles, or poor quality. Similarly, this error shows up when your configuration file includes target Framework but the server doesn’t support .NET 4.0 yet. The solution? Make sure your hosting environment is properly upgraded and your IIS (Internet Information Services) is configured to use the right .NET version.
