ASP.NET connectionstring does not conform to specification

Question

Hy!

I am writing an asp.net application. I use entityframework 5 code first. I develop this site local, but I use the database of the webserver. When I publish this site to the webserver, I have to add the connection string in this way:

<add name="strConn" connectionString="Data Source=localhost;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD" />

instead of it:

 <add name="constringtwo" connectionString="Server=plumeria.arvixe.com,1433;Database=DBNAME;User Id=DBUSERNAME;Password=DBPASSWORD;" providerName="System.Data.SqlClient" />

when I try to open my website I got an exception. I wrote to the support I got this answer:

You appear to be trying to attach a database,

<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-iAdmin.Web-20130813125200;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-iAdmin.Web-20130813125200.mdf" providerName="System.Data.SqlClient" />

I do not understand, because I have already deleted this connectionstring, how would it be? I wrote the name of my connection string to the main datacontext, usercontext, and the websecurity.init.

thank you anticipation

Answer 1

Is it possible that you have a semicolon in your password?

For example, I can reproduce your exception by doing this:

new SqlConnection("Data Source=localhost;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWOR;D;")

But if I remove the semicolon from the password, it works.

Answer 2

You may be inheriting connection strings from a higher-level web.config or machine.config. To avoid this, consider adding a <clear/> element to the connectionStrings configuration section:

<connectionStrings>
    <clear/>
    <add name=... />
    ...

Also from your stack trace, it looks like it's SimpleMembershipProvider that's trying to use the offending connection string. You might want to remove SimpleMembershipProvider from your configuration, or configure it to use a different connection string.
