Where is ConfigurationManager's namespace?

Question

I\'ve got a reference to System.Configuration - and ConfigurationSettings is found no problem - but the type or namespace \'ConfigurationMana

Answer 1

For me, this problem was solved when I put the "BuildConnectionString" function in a class and added "Imports System.Configuration" at the top of the class page. I did as the Microsoft site itself says. https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/connection-string-builders

Private Sub BuildConnectionString(ByVal dataSource As String, _
ByVal userName As String, ByVal userPassword As String)

' Retrieve the partial connection string named databaseConnection
' from the application's app.config or web.config file.
Dim settings As ConnectionStringSettings = _
   ConfigurationManager.ConnectionStrings("partialConnectString")

If Not settings Is Nothing Then
    ' Retrieve the partial connection string.
    Dim connectString As String = settings.ConnectionString
    Console.WriteLine("Original: {0}", connectString)

    ' Create a new SqlConnectionStringBuilder based on the
    ' partial connection string retrieved from the config file.
    Dim builder As New SqlConnectionStringBuilder(connectString)

    ' Supply the additional values.
    builder.DataSource = dataSource
    builder.UserID = userName
    builder.Password = userPassword

    Console.WriteLine("Modified: {0}", builder.ConnectionString)
End If
End Sub

The important point is to use the function in the class. When I did this the error failed to find the source.
