I am trying to load my cameras using the MIP SDK 2018 on an ASP .NET MVC Web api. "Could not load file or assembly 'VideoOS.DatabaseUtility.Common' or one of its dependencies. An attempt was made to load a program with an incorrect format."

Hi Arun, I spun up a test ASP.NET MVC project without changing any properties and as I expected, I got the same result. Since the MIP SDK binaries are exclusively x64 bitness, you’ll need to visit the properties of your web application, and make the following changes:

Build tab → Platform target: x64 (this ensures the project is built targeting x64 to match the referenced SDK dlls

Web tab → Servers → IIS Express / Bitness: x64 (this launches a 64bit version of IIS Express in the debugger)

Does making these two changes resolve the issue for you as well?

Thanks for the reply. I tried what you suggested and now I get a different error message.

"Could not load file or assembly ‘VideoOS.DatabaseUtility.Common.DLL’ or one of its dependencies. The specified module could not be found."

That message usually means there is a dependency dll missing. You don’t usually need ALL the binaries included in the MIP SDK but as a test, you might copy all of them into your build directory to confirm the error is due to a missing dependency.

Strange but removing the VideoOS.DatabaseUtility.Common.DLL from the build directory fixed the issue. And the webapi loads.
