Hi,

This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
        {
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        }


Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

 

On web.config I already have this:
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Thanks.

The Microsoft® . NET Framework versions 1. 0 and 1. 1 represented major changes in software development. However, one important thing that did not change much was support for distributed transactions.

Exchange 2000 WSS: Web Storage System Improves Exchange Data Accessibility

  

The Web Storage System (WSS) in Exchange 2000 is a Web-accessible database that stores any type of data such as e-mail, contacts, appointments, threaded discussions, and multimedia files, and renders the data in HTML in any browser. WSS is based on Internet standards, therefore data can be accessed through URLs, an Exchange OLE DB provider, drive mapping, XML, and Web Documenting and Versioning (WebDAV). This article discusses the WSS schema and how to extend the default schema for custom data. A sample application that uses a custom schema and a custom form to display WSS data is available for download.

Business Data Error: System.OverFlowException

  

I have a Business Data Catalog file I've uploaded to connect to our back end Firebird DBMS through ODBC.

The SharePoint server is MOSS 2007 x64. The web front end server(s) all have an x64 Firebird Engine and ODBC driver with verified connectivity to Firebird.

When I use one of the methods, I can see connections being made to our Firebird server and the query being passed. I know the query returns results (it's a stored procedure with no parameters), but I get the following error "An error occurred while retrieving data from MROTest1. Administrators, see the server log for more information" in IE. If I look in the server logs, I see (12\Hive\Logs)

Fed Up With System.Data.Metadata.Edm.ObjectItemAssemblyLoader

  
I'm fed up with the random errors I'm getting on my ASP.NET 4, Entity Framework 4 web application lately. It seems to stem from something that System.Data.Metadata.Edm is doing with a call to System.Reflection.Assembly.GetTypes(). I keep getting the error that I complained about previously : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. To display those Loader exceptions, I added the following to my global.asax file: Sub Application_Error...(read more)
