log4net.ext.json：錯誤無法找到類型[log4net.Layout.SerializedLayout，log4net.Ext.Json]

Question

我已經安裝了nuget包log4net.Ext.Json和first steps instructions從維基。

不過，我在運行時獲得以下錯誤：

log4net:ERROR Failed to find type [log4net.Layout.SerializedLayout, log4net.Ext.Json]

我該如何解決這個問題？

您的輸出/運行目錄中缺少dll log4net.Ext.Json.dll，或者dll log4net.Ext.Json.dll不包含類log4net.Layout.SerializedLayout。首先檢查dll，如果沒有，則將其複製到目錄中。
