Thanks for reporting the issue. The issue is now fixed in Visual Studio 2012 RTM.

Hi Riderman,

Thanks for confirming. We do have a fix for this issue internally, and it will be included in the next release for VS2012. In the meantime, the suggested workaround is to comment out the line with <clear />. If you need to remove specific strings, you can use a <remove ... /> element instead.

Thanks,

Yes. follow my setup (connectionStrings)

<connectionStrings>
    <clear />
    <remove name="LocalSqlServer" />
    <add name="Data" connectionString="Server=.;Database=datafilme.com.br;Integrated Security=true;" providerName="System.Data.SqlClient" />
</connectionStrings>

Hi Riderman,

We have a bug in VS2012 RC where this error will occur if any elements under your <connectionStrings> node do not have a name attribute. Most commonly, this happens if you have a <clear />. Can you confirm if this is the same issue?

Thanks,
