  I'm having the same problem now...why?   The first thing you read when you open up a book on Visual C# 2008 and Linq is that there's nothing to install.   Linq is supposed to just be there.  I didn't have any luck with the fixes above; this is using VS2010 Beta 2.

  I am ready to scream at this... Please help!

  
  

  I got this after I added another table to the "SQL to LINQ" dbml item.

  One table it was fine, working great, add second table and third table this stuff starts happening.

  
  

  
  

  This is my assembly:

  
  

  <compilation debug="true">
  			<assemblies>
  				<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
  				<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  				<add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
  				<add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
  				<add assembly="System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
  			</assemblies>
  		</compilation>

  
  
  

  
  

  Codedom:

  
  

  	<system.codedom>
  		<compilers>
  			<compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
  				<providerOption name="CompilerVersion" value="v3.5"/>
  				<providerOption name="WarnAsError" value="false"/></compiler>
  			<compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
  				<providerOption name="CompilerVersion" value="v3.5"/>
  				<providerOption name="OptionInfer" value="true"/>
  				<providerOption name="WarnAsError" value="false"/></compiler></compilers></system.codedom>

  Figured it out, my Table name was "Systems"  which made it have the class "System" and System is of course a reserved word.....  Renames it to AllSystem and everything worked perfect   ....  what a waste of time
