我的sql为代码优先实体框架提供6.4.3.0支持

Question

I'm using my sql 6.4.3.0 in server and it returns error:

 'The provider did not return a ProviderManifestToken string.'

But in my local, my sql v-6.4.4.0 creating database well, but in my server not creating database. Is that my sql provider supports core first entity framework without database?

在阅读了几篇文章后，您的问题很可能是您的我的sql 6.4.3.0版本的版本。我相信您应该将版本sql v-6.4.4.0更新为您使用的版本或下载最新版本，并保留一个好主意。本地和发展尽可能相似。
