I have the E-Book "Getting Started with the Entity Framework 4.1 Using ASP.NET MVC".pdf which states that the requirements are VS 2010 SP1. I've fulfilled that and the other requirements. However, the link "download the completed application" brings me HERE and the requirements to create, build and run the sample are now different. So, where is the source code to the VS 2010 MVC 3 version? I don't WANT to build the "latest" version - for a SPECIFIC REASON.
Here's a link to the C# MVC 3 project: http://archive.
msdn.microsoft. com/Project/Dow nload/FileDownl oad.aspx?Projec tName=aspnetmsd nexamples&Downl oadId=16474 We forgot to re-post the old version somewhere when we updated the sample for MVC 4 EF 5.
Thank you, Tom. Much appreciated.
Hi Tom, I was aslo looking for the MVC 3 version sample code and tried the URL you have mentioned here. But it is not available there. So can you please share the correct link to download MVC3 with EF 4.1 sample code. Hi vedicwarrior If you got the sample, please share it, this would be really helpful.
@kpant, I'm sorry but the site where we were hosting the download was retired rather suddenly without our team getting enough advance notice to find an alternative. We're working on getting the files back and finding a new hosting location and when that happens I'll provide a new link.
@kpant - The MVC3 sample is now hosted at http://code.msd
n.microsoft.com /Getting-Starte d-with-abeed7be .
I found that you are using UnitOfWork only in CourseControlle
r like private UnitOfWork unitOfWork = new UnitOfWork(); And in rest controllers you are directly using DbContext. Why is this? It will be good if could you modify the code with Dependency Injection or IOC container? Thanks
The downloadable project is exactly as it would be created if you worked through the tutorial. The UnitOfWork class is added in one of the later tutorials as an example of how to implement that pattern, and having shown the example there was no need to go back and add it to controllers that had been created earlier. Thanks for the suggestion, we'll consider adding dependency injection in a later edition of the tutorial.
I agree, this is the way to go. Nice sample!
I download your project example. when I click the page, it show can't find dbo.student. I try to look database table but I don't see that student table, just see Course, CourseInstructo
r, Department, Enrollment, OfficeAssignmen t and Person. what happen?
Try changing the database name in Web.config and running update-database again.
Hi Tom how can I manage unique constraint please.
For questions not about the sample/tutorial itself, see StackOverflow or the ASP.NET EF forum (links at the top of the first page in the tutorial series).
hi Tom can i please have the documentation to c how the code flows please please its working perfect
See the Description tab -- there's a link to the tutorial series that shows how to build the application from scratch.
.com report please Tom
Hi Tom: I can't attach file CU10.mdf to database. Do you have any script to do that?
If you mean update-database creates the file but it won't attach, chances are you already used the CU10 name. Go into Web.config and change the name of the database or delete the existing database. For instructions on how to change the name, see the note near the end of the fourth tutorial: http://www.asp.

HI Tom : Can't find database CU10.mdf......A
pp_Data folder is empty
In the Description under Getting Start there are build and run instructions -- one of the steps is to run the Update-Database command. That creates the database; the database .mdf file isn't included in the download.
Hi Tom: When I tried to run your application, everything worked until it tried to attach the file CU10.mdf to the database whereupon it choked. I couldn't find this file anywhere in the download. Am I missing something? Roger S
Whoops - I guess my local system doesn't handle attach well - removed that from the connection strings and database built like a charm - thanks - looking forward to going though this. Roger
I too encountered this error in the Package Manager after running 'Update-Databas
e' to set up the project. The error I received was: Cannot attach the file 'C:\Users\Rich\ Documents\Visua l Studio 2013\Projects\E FCF\C#\ContosoU niversity\App_D ata\CU10.mdf' as database 'CU10'. The reason for this was that I had previously set the solution up and an instance of the CU10 database was already attached. To resolve I logged into the '(LocalDB\v11.0 )' dataabse in SQL Server Management Studio and deleted the CU10 database that was there. I reran the command and all is well once again in LaLa Land.
Hi Tom, as described in "MVC ModelBinding Vulnerability in Contoso University sample (first raw PoC)" http://blog.din
iscruz.com/2013 /07/mvc-modelbi nding-vulnerabi lity-in.html there are a number of MVC ModelBinding Vulnerabilities in this application. I would like to use this application has an example of how to fix these issues, so have you added this code to GitHub? (so that I can fork it and make my code changes there?)
We've updated the application both here in Code Gallery and on the archive.msdn site where the chapter downloads are stored. I'm not aware that there is a copy of this project on GitHub -- if someone has put one there I don't have control over it. The download project shows one method to address the vulnerability - using the Bind attribute. Another method is to use view models and not bind directly to entity classes. The options are discussed in a new security note sidebar in tutorial #2.
I believe it is better to rely on the available links in Gallery MSDN
