I notised after upgrading to the latest version of EPiServer find that I did not get any results back.

I did a new simple function that look's like this:

public void ExtremeSimpleSearch()
{
	try
	{
		var queryResult = SearchClient.Instance.Search<EducationInfoToIndex>().For("lernia").GetResult();
	}
	catch (Exception exception)
	{
		_logger.Error("EPiServer Find fel", exception);
	}
	
}

EducationInfoToIndex is a custom object that does not inherit from IContent and the error I get is this:

{System.IO.FileLoadException: Could not load file or assembly 'EPiServer.Find, Version=7.5.450.89, Culture=neutral, PublicKeyToken=8fe83dea738b45b7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
