I have deployed one web project into Azure emulator. And I get this error saying that Could not load file or assembly Base. The thing is that this web project, got dependencies to another project in the same solution. I have added that dependency into the reference list of my web project. And if I run this web application without using the azure emulator it will run fine. But I will get error when I try to run it on the azure emulator.

At first glance I thought that I maybe need to add the other project as role also. But it couldn't be that. Anyone know what the problem might be?

I hope I got enough data for you to look into.

My solution structure looks like following

Solution

• Base
• WebAPI
• WebAPI.Azure

And it is the WebAPI that has a dependency to the Base project

Here's the Assembly load trace

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
