    <WebMethod()> _
    Public Shared Sub DoSomething(ByVal s As String)
        If HttpContext.Current.Session("View") Is Nothing Then

A static member cannot access an instance member without creating an instance of that class. Have you considered making "uploadcount" static?

Well it would be something like below. But I don't think you are going to get the results you are expecting, which is why I suggested marking your private variable as "Shared".
<WebMethod()> _
Public Shared Sub DoSomething(ByVal s As String)
    Dim m as New Main()
 
    m.uploadcount += 1
 
    If HttpContext.Current.Session("View") Is Nothing Then
         HttpContext.Current.Session("View") = 1 ' 1: Details List
 
    End If
End Sub

Partial Public Class Main
    Inherits System.Web.UI.Page
    Public Shared uploadcount As Integer = 0
 
 
    <WebMethod()> _
    Public Shared Sub DoSomething(ByVal s As String)
    	Main.uploadcount += 1
    
        If HttpContext.Current.Session("View") Is Nothing Then
            HttpContext.Current.Session("View") = 1 ' 1: Details List
 
        End If
 
     End sub
 
End Class
