我的sql為代碼優先實體框架提供6.4.3.0支持

Question

我在服務器上使用sql 6.4.3.0，它返回錯誤：

 'The provider did not return a ProviderManifestToken string.'

但是在我的本地環境中，我的sql v-6.4.4.0創建數據庫的很好，但是在我的服務器中卻沒有創建數據庫。 我的sql provider是否支持沒有數據庫的核心第一個實體框架？

在閱讀了幾篇文章后，您的問題很可能是您的我的sql 6.4.3.0版本的版本。我相信您應該將版本sql v-6.4.4.0更新為您使用的版本或下載最新版本，並保留一個好主意。本地和發展盡可能相似。
