The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Question

After signing the third parties assemblies and adding them to GAC I am getting the below error: also the Assembly Binder Log Entry shows this error

It says mismatch

Answer 1

I got this error using FASTjson:

_jsonConfig = fastJSON.JSON.ToObject(jsonConfigFileContents);

It failed on this line:

Type t = Type.GetType(typename);

Which causes an exception in System.RuntimeTypeHandle.GetTypeByName

---

The problem was a difference in the JSON file compared to the JSON Object Model.

The solution is to re-save the JSON Object Model to file, eg:

string jsonSettings = fastJSON.JSON.ToJSON(JSONObjectModel);
File.WriteAllText(JSONFilePath, jsonSettings);
