I am new to LINQ but I would liek to start using it my web apps. I am trying to configure the linqdatasource but it asks for a datacontext object. Has anyone found any good tutorials for creating linqdatasources? OR can someone help me get started in
creating the datacontext object so I can use it in the linqdatasource. Thanks in advance!
I have created the dbml file inside of the project. I dragged a linqdatasource to my web page and am trying to configure it. But the CHoose Context Object dropdown doesn't contain my dbml file. Any ideas?
Ok...I got the linqdatasource created. Now when I view in browser I get the following error:
Description:

Did you try building the project? When using the Linqdatasource you need to build the project to get he datacontext object visible in code.
Thanks,

Please make sure that you've imported the：
1）system.Data.Linq.Mapping（as Namespace）
2）System.Data.Linq.dll
And then you can use "Database(……)" directly, "Attribute" can be ignored when using an attribute.
Reguards!
