chapter 13: context object problem
hi.
in ch13 when i create the planetWrox.dbml and use the planetWroxDataContext in the dataSource it works fine in the first time, but after i restart webdeveloper and try to configurate the data source I get this message when I try using planetWroxDataContext:
HTML Code:
if the type 'PlanetWroxDataContext' located in app_code folder, please check that it compiles. If the type is located in a compiled assembly, please check that the assembly is referenced by the project.
what is the problem and how do i fix it?

Hi there,
Is that the complete error message? Also, do you see error messages in the Error List when you build the web site? And did you create a Web Site (File | New Web Site) or a Web Application (File | New Project)?

yes it's the complete error message, but also when I press F5 to start debugging it throws me this error in the error list:
HTML Code:
Error 1 The type or namespace name 'Linq' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) C: - *my physical folder* - \App_Code\PlanetWrox.designer.cs 16 19 C:\...\Site\
but the site works fine when i open in browser.
I pretty sure I did a new website and not project..
but in your site there is no problem like that (source/chapter 13) so I guess I did something wrong but I don't know what it is..
here is a screenshot if it helps:

Hmmm, weird indeed. Can you post the code for the web.config file. Or better yet, send me a zipped copy of the entire site so I can take a look?

Your site seems to be a mix of ASP.NET 3.5 and ASP.NET 4. Here's how to fix the issue.
1. Right-click the project in the Solution Explorer and choose Property Pages
2. In the Build category, set Target Framework to .NET Framework 4
3. Click OK
The errors should then all be gone. When you click OK, VWD fixes the settings (such as assembly references) in the web.config file.
Optionally, you can repeat these steps and switch back to .NET 3.5 if that's what you want / require.
Cheers,
Imar
