Namespace or type specified in the project-level Imports ‘System.Xml.Linq’ doesn’t contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn’t use any aliases
There are 2 ways to remove this warning
First, you may need to convert the current .Net Framework used by the application to higher version, let’s say from .net framework 2 to 3.5
- Goto Property Pages of the web site project
- View Menu->Property Pages or press shift+F4
- Click the Build option from the left side
- Make sure the Target Framework is .Net Framework 3.5
Second, remove the namespace that shown in the warning in this case the “System.Xml.Linq” from the web.config
namespace linq

How to Enumerate SQL Server Instance
To Enumerate or detect installed SQL Server in the Local Network use System.Data.Sql Namespace;
Imports System.Data
Imports System.Data.Sql
Public Function getSqlInstance() as DataTable
sDim sqlEnum As Sql.SqlDataSourceEnumerator
sDim dt As DataTable
sqlEnum = Sql.SqlDataSourceEnumerator.Instance
dt = sqlEnum.GetDataSources
Return dt
End Function
Columns:
ServerName – Name of the server.
InstanceName – Name of the server instance. Blank if the server is running as the default instance.
IsClustered – Indicates whether the server is part of a cluster.
Version – Version of the server (8.00.x for SQL Server 2000, and 9.00.x for SQL Server 2005).
Enumeration Limitations
All of the available servers may or may not be listed. The list can vary depending on factors such as timeouts and network traffic. This can cause the list to be different on two consecutive calls. Only servers on the same network will be listed. Broadcast packets typically won’t traverse routers, which is why you may not see a server listed, but it will be stable across calls.
Listed servers may or may not have additional information such as IsClustered and version. This is dependent on how the list was obtained. Servers listed through the SQL Server browser service will have more details than those found through the Windows infrastructure, which will list only the name.
