Can not load my own file or assembly

Question

I have created two projects in one solution and the idea is that I want to have one project call a method in the other project. I have added the called project as a reference to the calling project, but when I try to run the code I get this error:

Additional information: Could not load file or assembly 'abc, Version=9.8.0.0, Culture=neutral, PublicKeyToken=4f047e93159395ca' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

When I paste the main method that is calling the method from the other project into the called project and only run that one it works fine. So it is likely not a problem with dependencies.

Are both projects using the same version of the .net framework? — Vijayanath Viswanathan, Oct 27 '17 at 15:51

@txtechhelp no i don't think it is a versioning problem since i am the one who wrote the two projects. — Allen Huang, Oct 27 '17 at 18:06
@MatthewWhited My projects dependencies are all working because if I take the code calling the other project and put it in that project it will work fine. — Allen Huang, Oct 27 '17 at 18:07
Do you have a version of "abc" in the GAC? `C:\Windows\assembly` — Matthew Whited, Oct 27 '17 at 18:40
Also try removing the SNK. It looks like you have a build order problem. — Matthew Whited, Oct 27 '17 at 18:41
@MatthewWhited I am unable to find 'abc' in the GAC. abc is a project within the same solution — Allen Huang, Oct 27 '17 at 18:45
@MatthewWhited there doesnt seem to be a SNK file in my project either — Allen Huang, Oct 27 '17 at 18:45
@MatthewWhited sorry im not too familiar with SNKs and am not sure where to find such a file — Allen Huang, Oct 27 '17 at 19:18
Check the signing page/sign the assembly under the project properties. — Matthew Whited, Oct 27 '17 at 19:26

Follow the steps bellow using adapting them to your needs.

In your Main project (the one you defined as startup project) right click on References > Add Reference > Projects and select the dependency.
Declare the dependency project with using and call the method from the other project in your main program.
Compile your solution, and check if the .dll of your dependency is in the same bin folder of your main application.
