推荐答案

也许这将是帮助你： visual studio - VS 2013 Error - 没有找到符合约束的导出： - Stack Overflow [ ^ ]


如果您的Visual Studio版本与SQL Server版本不匹配，也会遇到问题。

就个人而言，我已经放弃了尝试从Visual Studio使用SQL Server，有太多的复杂问题，我只是使用代码来连接和执行SQL命令。



如果你想使用的数据库是高效，真正免费且易于安装，我可以推荐 PostgreSQL 与C＃的 NpgSQL 驱动程序相结合，增加的好处是它可以在多个平台上运行。

Maybe this will be of help to you: visual studio - VS 2013 Error-"No exports were found that match the constraint:" - Stack Overflow[^]

Also you can run into problems if your version of Visual Studio does not match the SQL Server version.
Personally I have given up on trying to use SQL Server from Visual Studio, there are too many complications, I just use code to connect and execute SQL commands.

If you want to use a database that is efficient, really free and easy to install, I can recommend PostgreSQL in combination with the NpgSQL driver for C#, added bonus is that it runs on multiple platforms.
