Upload Large File of More Than 5 MB From Silverlight to Server Location Using WCF

This article is based on the article File Upload from Silverlight using WCF. So please read it before proceeding with this article.

A while back I wrote an article on uploading a File from Silverlight to a server location using WCF. I found my own article quiet useful. However, when I reread and implemented the code, I mentioned in the article, I found a few discrepancies:

    Code was unable to upload file with sizes in MB
    There was a bug in binding configuration.

In this article, I am going to rectify the above two bugs.

First modify basicHttpBinding as below:

Configure Endpoint as below:

So far everything is fine and if you run the code, you will be able to upload a file of a maximum size of 3MB. I tested it and I was able to upload a document file of 2.75 MB in size.

Now the question becomes, what if we want to upload a file of about 10 MB in size?

For that we need to reconfigure the things in the configuration file:

1.     Configure service behavior maximum number of items to serialize or deserialize.
2.     Configure HTTP Request length limit.
