Silverlight Error Message Code 4001


Dear Edward,

About the silverlight Error message with code 4001 and Error type: Download Error,It seems that some files are needed while publishing and not found.I think that when you are going to publish the application you check the option "Only files needed to run the application".  What about trying to publish the application using the option "All project files" and publish all the project files.  Also, if you have any images uploaded in your development server, make sure to copy all the files in the folder "WEBImagesThumbnails*.*". Hope this may help you.

Best of luck

This problem tends to generally occurs when Silverlight cannot voluntarily navigate authentication when the challenge in connection occurs.

This problem often occurs while using WMS Negotiate Authentication.

I am afraid that presently there’s no authentic and reliable solution to this problem. Microsoft is of course conscious of this problem and is dealing to provide a solution.

I hope this information serves your cause.
