What DLL is it saying it is missing? That error message usually specifies. I highly doubt every last DLL is missing.

Could not load file or assembly 'eWorld.UI' or one of its dependencies. The system cannot find the file specified.But I copied the eworld.ui dll also to the test server.

"I tries to change the application pool settings in IIS serevr locally", I have no idea why you think that would fix anything. The error message is perfectly clear. You are missing a file or a file the you are depending on.

I have copied the eworld.ui dll to the bin folder in teste server.Buyt still it could load the file or asembly.

Did you copy the entire bin folder to your test server? If you did and it still isn't working did you need to install this eworld app in any way, ie did it have an installer or a command line you had to run to get it working? If so it will be depending on some dll elsewhere (maybe in the GAC) so you'll need to install the app on the test server too.

Since it is not in your bin folder it is probably something that is installed on your machine but not on the server. Regardless, the error will tell you which dll it is. Then all you have to do is copy it or install the software on the server. You can set Copy Local = true on the reference so that the dll gets copied to the bin folder.

I did n't find the copy Local property in visual studio 2010.

Expand References in Solution Explorer. Select the Reference and below in the Properties window is where you will find it.

I have opened the application as website not as project.I did n't find the copy Local property

ZurdoDev 3-Oct-16 15:29pm

Regardless, you need to make sure all dlls are available on the server.

priya9826 3-Oct-16 15:36pm

I am sure about the dlls in the server.
Locally itrs working fine.When I am copying the files to the test server.Its throwing this error

ZurdoDev 3-Oct-16 15:37pm

That's because the dll is missing or the permissions to the folder where it's at are messed up. The error is not lying to you.
