sry cant post all coding, but i already post important part.
using telerik, masterpage, mvc3

error 1)
the type or namespace name SysMaterial could not be found (are you missing a using directive or an assembly reference?)

error 2)
found conflicts between different version of the same dependent assembly <-- this one just solve already, i run telerik ->open access -> option -> IntelliTrace -> enable. then restart VS2010 then run telerik ->open access ->upgrade reference

framework already is 4.0.

beside, i have search all article for adding reference, or change framework 4.0 client to framework 4.0 are not work for me.

needed your guy advice for help, thanks.

Are you serious? Not a single line of code show, and yet you want us to solve your problem. What article, for goodness sake? What are you even talking about?

_Damian S_ 6-Aug-13 2:19am

ROFL... you asked for code!! ;-)

♥…ЯҠ…♥ 6-Aug-13 0:38am

Above error refers to assembly that is not referenced in your application, Do onething come up with source code we'll try to come up with solution then

Sergey Alexandrovich Kryukov 6-Aug-13 0:56am

If OP failed to realize that she/he did not really provide relevant information in first place, it's hard to expect clear answers to our questions. However, let's see...

actually i most for think is system problem....

Richard MacCutchan 6-Aug-13 3:28am

No, it's a developer problem.

kangyi.lee 6-Aug-13 4:15am

what ever la, now headache on that issue

Richard MacCutchan 6-Aug-13 3:28am

error 1: where is the assembly that contains the SysMaterial class? Are you sure it has been added to your project references?

kangyi.lee 6-Aug-13 4:03am

FA.DAL --> FA

Richard MacCutchan 6-Aug-13 4:14am

Is that supposed to explain something?

Go back to your project and fix the problem, which is quite clear from the error message you receive. If you really don't understand what the problem is then go back to the documentation and review the section on references and #using directives.

kangyi.lee 6-Aug-13 4:37am

thanks for reply, i will try to fix it what going on

Sergey Alexandrovich Kryukov 6-Aug-13 11:33am

Do you actually know how to reference assemblies? How to name existing types?
