Compiler Warning CS1701 when using csc.exe

I'm trying to compile by command line a series of cs into a dll which uses Telerik.Web.UI.dll.

It compiles but I don't understand why I get this CS1701 warning about assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' as it says it's not sure it corresponds to 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' and that I should provide a runtime strategy.

What all this mumbo jumbo, how to fix it ?

Update: command line used

C:\Windows\Microsoft.NET\Framework\v3.5\csc.exe /t:library *.cs /out:test.dll /r:"C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q3 2009\Bin\Telerik.Web.UI.dll"

It sounds as if your project is using .NET 3.5 and you have a .NET 1 version of System.Web.Extensions. Make sure all of your dlls are using .NET 3.5.

You'll have to assume certain responsibilities to get command-line compiling right. That includes uses the correct /reference options and making sure that the correct version of csc.exe gets started so it uses the correct .rsp file. The real source of the warning (which you should not ignore) is unguessable if you don't post the command line that you used.
