Exception loading mpk file

[YaronAvraham]

I'm trying to load mpk file called "l_3" using LocalMapService and get this exception 

"Failed to create service l_3 MapServer. Service failed to initialize: Error unpacking map package hr=0x80004005 (No ErrorInfo)"

this is my code:

var mapService = new LocalMapService(fileName);

 await mapService.StartAsync();

StartAsync throws the exception.

I can open the same mpk file on ArcGIS Pro without any problems.

Thanks.

Some questions and things to check:

- What are the contents of the mpk? like types of layers, any networks etc.

- What version of ArcGIS Runtime SDK .Net / are you you using?

- If you put a try catch around StartAsync() do you get any additional information?

- Sometimes output window prints out relevant information too. Do you see anything written out there that may be associated to this mpk?
