Upload/Download Files with Silvelright and Entity Framework

I need a solution to Upload Files (of any type) using a Silvelright 4 client and using Entity Framework 4 to make the connection with the database. After the files are uploaded how can I download them from the server. Additionally but not necessary would be cool to gro开发者_Go百科up some files and been able to download them in a ZIP file.

Thanks in advanced.

You could do this with Silverlight 4, WCF RIA services and EF4.

You build a domainService that allows you to pass the uploaded file from the Silverlight client to the server. The domainService persists your file into a backend database.

Gaining access to the files that have been uploaded can be via the WCF RIA service domainService but accessing its SOAP endpoint or ODATA endpoint.

OR

You could expose the files using an ADO.NET Data Services project giving you more control on the ODATA endpoint, even including the file grouping and zipping.
