HRESULT: 0x80131040: The located assembly's manifest definition does not match the assembly reference

Question

The located assembly\'s manifest definition does not match the assembly reference

getting this when running nunit through ncover. Any idea?

Answer 1

I ran into this issue in a web api project.

Api project was using a nuget package of a library with version 3. And one of the referenced assemblies say X was using older version of the same nuget package with version 2.

Whenever referenced assembly is built or any other project referencing X is rebuilt, api project's assemblies gets updated with lower version. And got this assembly reference error.

Rebuild works but in my case I wanted a long term solution.

I made the assemblies reference same version of nuget package.
