missing "linq" assembly? tried several fixes and no luck

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net

Newbie at this so pardon me from the onset...

I'm building a site using VWD 2010 Express.  The site seems to run fine in the browser but when debugging I get the following errors:

Error 1 c:\....\Site.master.cs(3): error CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?)  (I get this message 4 times)

Error 5 The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?) 

I've gone in to the Web.config and added the following:


<add assembly

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=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, 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?


The type 'DataGrid' was not found. Verify that you are not missing an assembly reference and that

Hi; I'm new to WPF and I was going through the ExpenseIt tutorial on MSDN's website. The tutorial was working fine until I added DataGrid. I got the error message: "The type 'DataGrid' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."     I could not find a clear answer online of which assembly references to fix and how to fix them. Any help would be appreciated. Thanks!     Note: I'm running the following: Windows Vista 32-bit operating system Microsoft Visual Studio 2008 Version 9.0.30729.1 SP Microsoft .NET Framework Version 3.5 SP1

Missing a cast in Linq Expression

 Hi, My code is: var results = from XPathNavigator res in iterator  where res.Select(xpath).Current.Value.Contains(param) select res; where iterator is XPathNodeIterator. I get the next error(on where ): Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<System.Xml.XPath.XPathNavigator>' to 'System.Linq.IOrderedEnumerable<System.Xml.XPath.XPathNavigator>'. An explicit conversion exists (are you missing a cast?) Where am I  missing a cast? Thanks, katzraya

Linq to SQL Template missing

Linq to SharePoint(SPMetal) Missing "Author" and "Editor"


So I have also noticed that using the SPMetal tool the CreatedBy(Author) and ModifiedBy(Editor) fields are missing from Entity Model generated by the SPMetal utility. So here is a nice post on manually adding them (http://blogs.microsoft.co.il/blogs/itaysk/archive/2010/02/19/spmetal-missing-created-by-modified-by-fields.aspx), but does anyone know if this is going to be fixed in the future or if there is a reason why they are not generated?


Playing with Linq grouping: GroupByMany?

One of its features is grouping. Many people understand grouping like it is defined in Sql. Linq is implementing grouping quite the same way. Let's discover this syntax and how to make consecutive groups easier.

LINQ : Implementing IN and NOT IN

Linq: how to share parameters between lambda expressions ?

When using Linq to objects, you will quickly feel the need to pass some parameters from a method to another but it's not so easy because each Linq method is not calling the following one. In a Linq sequence, each method is using the result computed by the previous one. So, local contexts are not visible from one method to another.
The compiler is using two technical different ways to let parameters go out of a method.

Linq to Sql CompiledQuery container

Ok now let's go. Here is just a little trick but with some interesting patterns that could be useful in some other contexts not connected to Linq to Sql.

When using Linq expressions, like with Linq to Sql, translating the expression into something else (sql for example) is taking time and resources. Sometimes it's negligible, sometimes not...

What is Lambda Expressions In LINQ

A lambda expression is an anonymous function that can contain expressions and statements, and can be used to create delegates or expression tree types.

All lambda expressions use the lambda operator =>, which is read as "goes to". The left side of the lambda operator specifies the input parameters (if any) and the right side holds the expression or statement block. The lambda expression x => x * x is read "x goes to x times x." This expression can be assigned to a delegate type as follows:
