Log4Net Database fun - connection strings!

Question

This works on dev:

 <connectionString name="asdf" value="Data Source=.\;Initial Catalog=fmwebapp1;Integrated Security=True" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

On live (a 64 bit VPS) this doesn't work:

<connectionString value="CT210991\SQLEXPRESS;Initial Catalog=fmwebapp1;Integrated Security=True" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

Error is:

log4net:ERROR [AdoNetAppender] Could not open database connection [CT210991\SQLEXPRESS;Initial Catalog=fmwebapp1;Integrated Security=True]
System.ArgumentException: Keyword not supported: 'ct210991\sqlexpress;initial catalog'.

   at System.Data.SqlClient.SqlConnection.ConnectionString_Set(String value)
   at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value)
   at log4net.Appender.AdoNetAppender.InitializeDatabaseConnection()

brain gone fuzzy.. 64 bit issue?

Answer 1

You don't have 'Data Source=' in front of 'CT210991\SQLEXPRESS' in your connectionString value.

Answer 2

D'Oh - missed out the Data Source=

Answer 3

You're missing the "Data Source" bit:

<connectionString value="Data Source=CT210991\SQLEXPRESS;Initial Catalog=fmwebapp1;Integrated Security=True" />
