在此之前，我必须向你们保证，这不是因为错误的连接字符串，我已经多次检查和测试过了！
所以在这里，显然这是一个众所周知的问题，很多人建议“纠正”连接字符串，但显然这不是我的解决方案。 我已经使用VS2013 Web Deploy工具在我从OVH（加拿大）购买的Windows 2012R2服务器上将我的Asp.NET MVC应用程序部署到iis。
所以这是web.config文件：

当我在服务器上尝试应用程序时，出现以下错误：
format of the initialization string does not conform to specification starting at index 0
有什么想法吗？我花了一整天时间仍然坚持......
