的web.config錯誤b77a5c561934e089

Question

我嘗試運行我的解決辦法，但是這表明在web.config中的錯誤

無法加載文件或程序集「System.ServiceModel，版本= 4.0.0.0，文化=中立，公鑰= b77a5c561934e089'或它的一個依賴關係。該系統找不到指定的文件。

這是web.config中

Answer 1

這主要是由於該目標框架版本和裝配版本不匹配的事實。從您的帖子看起來像目標框架是4.5.1。檢查並確保System.ServiceModel的組件版本也相同。

<httpRuntime targetFramework="4.5.1" />
