ASP.NET caching with SQL Server doesn't work. Help needed.

[Toni]

Hello! I'm trying to get caching work with ASP.NET 2.0 and SQL Server
Express Edition 2005, but I have a problem and I can't figure out what I'm
still doing wrong.

I have enabled the database for cache notification by running the
aspnet_regsql tool on the command line:
aspnet_regsql -S server -E -d database -et

Then I have run the aspnet_regsql tool to enable each table in the database
for cache notification:
aspnet_regsql -S server -E -d database -et -t tablename

I have added the necessary parts into web.config file, so that it is
like this:

<connectionStrings>
<add name="ConnectionString1" connectionString="Data
Source=servername;Database=databasename;Integrated Security=True"
providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<caching>
<sqlCacheDependency enabled="true" pollTime="2000">
<databases>
<add connectionStringName="ConnectionString1"
name="KJ"/>
</databases>
</sqlCacheDependency>

</caching>

I have added this into global.asax file for the application start event:
System.Data.SqlClient.SqlDependency.Start(ConfigurationManager.ConnectionStrings("ConnectionString1").ToString())

Then I wrote this code where I get data from the table MAAKUNNAT in the
database.
----------
SqlCacheDependencyAdmin.EnableTableForNotifications(ConfigurationManager.ConnectionStrings("ConnectionString1").ToString(),
"MAAKUNNAT")
Dim maakunnatDS As New DataSet

If Cache.Get("maakunnat") Is Nothing Then
Dim myConnection As New
SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString1").ToString())
myConnection.Open()

Dim cmd As New SqlCommand("haemaakunnat", myConnection)
cmd.CommandType = CommandType.StoredProcedure
Dim riippuvuus As New SqlCacheDependency("KJ", "MAAKUNNAT")
Dim aggDep As New AggregateCacheDependency
aggDep.Add(riippuvuus)

Dim maakunnatDA As SqlDataAdapter = New SqlDataAdapter
maakunnatDA.SelectCommand = cmd

maakunnatDA.Fill(maakunnatDS, "MAAKUNTA")
myConnection.Close()
Cache.Insert("maakunnat", maakunnatDS, aggDep)

Else
Response.Write("The data is in the cache")
maakunnatDS = Cache.Get("maakunnat")
End If
-----------------
When I run the page I get this error.
------------------------------------------

The 'MAAKUNNAT' table in the database 'KJ' is not enabled for SQL cache
notification.

Please make sure the table exists, and the table name used for cache
dependency matches exactly the table name used in cache notification
registration.

To enable a table for SQL cache notification, please use
SqlCacheDependencyAdmin.EnableTableForNotifications method, or the command
line tool aspnet_regsql. To use the tool, please run 'aspnet_regsql.exe -?'
for more information.

To get a list of enabled tables in the database, please use
SqlCacheDependencyManager.GetTablesEnabledForNotifications method, or the
command line tool aspnet_regsql.exe.
----------------------------------------------
When I run the aspnet_regsql tool with the -lt parameter to get a list of
enabled tables in the database they are all enabled. Thank you very much in
advance if someone could help me with this problem.
