How to Fix System.ServiceModel.dll Errors Without Downloading

Do not download individual DLL files from third-party websites, as they often contain malware or outdated versions. Use these built-in native Windows methods instead.

Method 1: Repair or Turn On.NET Framework

大多数 System.ServiceModel.dll errors happen because WCF features are turned off or corrupted.

按下 Win + R, 类型 optionalfeatures.exe,然后按下 Enter.
找到了 .NET Framework 3.5 这里是我的家. .NET Framework 4.8 Advanced Services (或您目前的版本).
Expand both categories and look for WCF Services.
检查旁边的框. WCF Services (specifically HTTP Activation and Non-HTTP Activation).
点击 OK, let Windows apply the changes, and restart your computer.

Method 2: Run the Deployment Image Servicing and Management (DISM) Tool

This tool repairs the underlying Windows component store using local system images.

按下右键 Start Menu 并且选择 Terminal (Admin) 或是 Command Prompt (Admin).
输入下面的命令并按下 Enter: DISM.exe /Online /Cleanup-image /Restorehealth
等待过程达到100%的完成.

Method 3: Run the System File Checker (SFC)

SFC scans all protected system files and replaces corrupted ones with a cached copy from the OS.

留下这个 Admin Command Prompt open from the previous step.
输入下面的命令并按下 Enter: sfc /scannow
Restart your PC after the verification finishes.

Method 4: Use the Microsoft.NET Framework Repair Tool

If the framework installation itself is broken, Microsoft provides a built-in self-repair mechanism via command line.

按下右键 Start Menu 并且选择 Command Prompt (Admin).
Execute the following command to force an internal verification of framework components: ndpfix.exe (Note: If this command is unrecognized, proceed to use Windows Update to push pending framework patches) .
