Hi folks,

  One of our web developers updated the web.config for our solutions web site program to work with ATLAS. The website runs fine and the ATLAS works, etc. ... but when i've come back into the Application Diagram to double check some stuff, i get this error now :-

Could not load type 'Microsoft.Web.Configuration.MicrosoftWebSectionGroup' from assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyTokey=b03f5f7f11d50a3a'.

er.... ?? The Application Digram also stops loading at that point.

When i comment out the SectionGroup and the microsoft.web section in the .config file (the red highlighted stuff), the diagram opens up. Is there something i need to registered with the solution????

Here is the config file btw.

Cheers :)

This is a known issue. The problem is that our code is unable to find the assembly that contains MicrosoftWebSectionGroup. You can work around the problem by doing the following:

1. Close any running instances of Visual Studio.

2. Copy "Program Files\Microsoft ASP.NET\Atlas\v2.0.50727\Atlas\Microsoft.Web.Atlas.dll" to "Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies".

3. Modify your config file to fully qualify the type names, as shown below (note the addition of the assembly name).

<sectionGroup name="microsoft.web" type="Microsoft.Web.Configuration.MicrosoftWebSectionGroup,Microsoft.Web.Atlas">

<section name="converters" type="Microsoft.Web.Configuration.ConvertersSection,Microsoft.Web.Atlas" requirePermission="false"/>

<section name="webServices" type="Microsoft.Web.Configuration.WebServicesSection,Microsoft.Web.Atlas" requirePermission="false"/>

<section name="authenticationService" type="Microsoft.Web.Configuration.AuthenticationServiceSection,Microsoft.Web.Atlas" requirePermission="false"/>

<section name="profileService" type="Microsoft.Web.Configuration.ProfileServiceSection,Microsoft.Web.Atlas" requirePermission="false"/>

</sectionGroup>

4. Restart Visual Studio.

At this point you should be able to open the Application Designer. Please let us know if this doesn't fix your problem.

Hello Ian,

thank you kindly for your reply. It worked perfectly. I would like to note one minor difference I was required to make to get this working. First of all, i didn't have ATLAS installed on my machine. Therefore, the folder Program Files\Microsoft ASP.NET\Atlas\v2.0.50727\Atlas\ does not exist. The .dll DOES exist in our solution so i was able to copy the .dll (which tfs source safe had retrieved for me at some point) and copy that .dll to the listed directory. Remember, the dll is used by our website only, which was why the website atlas stuff worked fine.

Now that the band-aid solution worked, will this be fixed in the future? Is there anyway the Distributed Diagrams can also reference any website references also? I'm not try to tell anyone how to do their job, just hopeing that issue will not get lost in these forums only.

Thanks again Ian - top stuff :)

I'm glad the workaround was successful. We're currently tracking the issue and it will be considered for inclusion in a future release.

Ian

I'm using VS2005 and July Atlas release and have this web service deployed locally;

using System;

using System.Data;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using Microsoft.ApplicationBlocks.Data;

[WebService(Namespace = "http://www.microsoft.com/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

public class Service : System.Web.Services.WebService

public Service () {

//Uncomment the following line if using designed components

//InitializeComponent();

[WebMethod]

public string getEmpnoForUser(string user)

string constr = "Data Source=SERVER;uid=USER;database=db;Password=password";

string empno = string.Empty;

try

string qry = "SELECT distinct emp_no FROM HH_MASTER WHERE rtrim(UserName)='" + user + "'";

empno = Convert.ToString(SqlHelper.ExecuteScalar(constr, CommandType.Text, qry));

catch (Exception ex)

empno = "(" + ex.ToString() + ")";

return empno;
