So? _Are_ you missing a using directive or an assembly reference?

The error means it can't find some code you're trying to use. You'll need to correct that.

How do identify this code problem? I put a break and it fail at the first statement

When you compile you get this error, right? It will tell you exactly where the problem is.

Find out in which assembly this type is defined and add that assembly; use proper type name.

How do I determine which assembly is missing? Do I add the assembly to web configure?

"Determine"? If you write some piece of code, say, some type name, in first place, you usually know what library you are using. If not, don't write anything. If it was written by some other developer, ask that developer. If that developer left the company without giving you all ins and outs, your company needs to develop proper way of preserving their asserts...

I did not write the code that is in question.
