Could not load file or assembly or one of its dependencies in library project

Question

I saw a lot of topic about this error (especially this one). But i'm unable to correct this error.

I have a solution C# WPF that I manage with visual studio 2017. My main project use a second one project. The second one project use a DLL, stored in a folder. Something like this :

MyClass use classes contained in MyDll (added in References as Embeded ressource, with dllNamspace). In MyClass I have :

public MyClass()
{
    dllNamspace.DllClass item = new dllNamspace.DllClass();
}

When I got to definition for DllClass, it's ok. I can see all functions/methods. But when I run MainProject, I have an Exception :

The type initializer for 'MyClass' threw an exception

With InnerException

Could not load file or assembly or one of its dependencies 'dllNamspace'

I've try to reload MyDll, rebuild all, add reference in MainProject, copy dll in bin folder. I always have this exception.

Right click on the properties and see from where this dll is being referenced. Also try a clean and build of your whole solution — King of the North, Mar 08 '18 at 11:43
Does your `MyDLL` need other Dlls? Are they in your Debug Folder? — Manfred Radlwimmer, Mar 08 '18 at 11:45
@KingoftheNorth you mean properties for the file or the project ? In already cleaned and rebuild all the solution but I have the error. — A.Pissicat, Mar 08 '18 at 11:49
@ManfredRadlwimmer I don't know if `MyDLL` needs other. How can I do ? — A.Pissicat, Mar 08 '18 at 11:50
Did you write it yourself? If not, which one is is it? Do you have a source? Did the source not mention any dependencies? — Manfred Radlwimmer, Mar 08 '18 at 11:52
Why an embedded resource? Try just setting its build action as copy to output so it can be found. — Crowcoder, Mar 08 '18 at 11:54
@A.Pissicat: i meant the properties of the dll, sorry. There should be a link to a log file containing the build details and error. — King of the North, Mar 08 '18 at 11:56
@KingoftheNorth properties does not help me. There is just the file name and build action — A.Pissicat, Mar 08 '18 at 12:03
Since you are embedding one assembly(dll) in another then have look at this thread. https://stackoverflow.com/questions/96732/embedding-one-dll-inside-another-as-an-embedded-resource-and-then-calling-it-fro — Pankaj Kapare, Mar 08 '18 at 12:06
@ManfredRadlwimmer the dll has been writer by a coworker. Unfortunately there is no documentation for this. But in the reference, I can see the dll in Object Browser. — A.Pissicat, Mar 08 '18 at 12:06
@A.Pissicat Then you are either targeting a different .Net version as the dll or the MyDLL needs another dll that you don't have. — Manfred Radlwimmer, Mar 08 '18 at 12:10
