WCF錯誤：當前禁用此服務的元數據發佈

Question

我想用basicHttpBinding配置發佈Web服務。我正在使用basicHttpBinding配置來增加65536字節的默認消息大小。我遇到的問題是，當我使用的web.config設置，如下圖所示，我得到一個錯誤：

Metadata publishing for this service is currently disabled.

我的主要目標是能夠增加默認郵件大小，並能保存二進制文件在數據庫中，因此任何其他配置是受歡迎的，但我試圖保持它儘可能簡單，以避免進一步的問題。

你能否指出我的配置有什麼問題？ Service.config代碼如下..

將此配置放入您的web.config中。
