Upload,Save and Retrieve Image from database by using their Id in Code First Method

from last 10 days I am trying many ways/example/tutorials which are provide in net to solve my problems. But, for all of those cases I fail down. I want to upload images for specific/multiple products, save them in database and display them in Home page by calling their ID. Can anyone give me step by step example/tutorials/link for this. Please don’t give an partial answer/suggestion. Because I am already bore about those.

Clean conflicting class files from Temporary ASP.NET Files

Class file Conflicts in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files is preventing me from building the solution. Even though I try emptying out the folder, each time Visual Studio starts the build process, it brings in the class file in to the temp folder with the same folder name. If I restart the machine or leave it overnight, project build without error. Is there anyway to tell Visual studio to delete/ignore/clean any lingering class files that could be in the temp folder?
