Could not load file or assembly 'System.Core, Version=3.5.0.0

[Urs]

Hi

 

My Web-Application generates following Error when starting the first page:
Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies

 

The Applicaiton was developed under Visual Studio 2005. The development machine has VS2008 installed, but never used it for that project.
I published copying the files and folders manually to the web server.

 

Any idea where I can fix this?

 

Thanks in advance.

Hello Urs,
You have references to this assembly in a aspx page, project references or a web.config file. When you remove those references everything should be ok.

Dear Dimitar
Thanks for the info.

If I look at Telerik.Openacess.dll with RedGate's Reflector I see that it depends on Windows.Base 3.0 !?

Any idea?

Hi Urs,
Yes it is, we need it for our ObservableCollection support.

Because .NET lazy loads all assemblies you could use OpenAccess nevertheless with .NET 2.0. If you do not have an ObservableCollection in your model we will not touch any .NET 3.0 code.

To analyse your problem can you provide us with more info?

Do you have a stacktrace showing the details. Or can you send me your application to test it here?

Hello Jan

 

Thanks for feedback:

1. System.Core, Version=3.5.0.0: I had a reference to .net 3.5 assembly in web.config. Can't imagine why.

2. Windows.Base 3.0: Just found that when searching for a solution.

This Thread is answered for me! Thank you
