Is VB.Net no longer supported? Even the prominently placed samples such as this one which links right from the MSDN Home-->Samples page neglects VB.Net.
At one point in time, nearly all samples and documentation were provided in both languages. Lately there seems to be a significant trend of VB.Net neglect to the point I'm concerned.
You sold us VB.Net. We learned it, we like it. Please don't make us second class citizens for having drank your Kool-Aide.
We suffer enough second class citizenship as it is for having chosen Microsoft platforms which significantly lack in the area of open source LOB development and efficient LOB development tooling. I doubt one could keep track of the number of Open source ERP and CRM systems on LAMP. There are exactly two on the Microsoft Stack and ORM and neither are well architected, stable and SQL Server based.
VB.NET is still supported; in some cases we only have time and resources to provide a given sample in one language, and that is often C#. For this particular sample there is a VB version of both the tutorial and the downloadable project, provided by Mike Brind -- see http://www.mikesdotnetting.com/article/241/mvc-5-with-ef-6-in-visual-basic-creating-an-entity-framework-data-model
I've read up to page 33 and implementation of your project. But when run project do not any data in tables! when I add a record in student table in database, I see it on browser. I check any problem in my project but i can not find any it in. When I place break point in seed method and debug my or your project (before I deleted database), re-create database but EF do not call seed method to populate test data in database. Pleas help me. Very Thansk.
If you run the project without executing the update-database command first, EF will run the createifnotexists initializer and the migrations Seed method won't run. Try changing the database name in Web.config and running update-database.
I downloaded and trying to get around with the Contoso University sample. So as I understand no additional repositories and unitofwork patterns need to be implemented since EF 6 incorporates these? What about the dependency injection? I don't see the dependency injection implemented here. why? Thanks.
The tutorial series and the sample app it creates isn't a comprehensive introduction to programming best practices; its purpose is to teach EF with MVC, so it avoids adding in other topics that might divert attention from EF/MVC. Mike Wasson has a great introduction to DI with Web API, and the principles for MVC are similar:
I found an issue in Contoso University. It is possible to tamper the HTTP Post when saving a student and provided a non-existing ID. As a result, the lookup will return a null response that fails.
It is necessary to verify the object. I wrote a blog post here http://blog.michaelhidalgo.info/2015/06/a-bug-in-contoso-university-sample.html
It is an issue, the code does not check if the studentToUpdate object is null.
Note that this code is also vulnerable to 'Insecure Direct Object References' https://www.owasp.org/index.php/Top_10_2010-A4-Insecure_Direct_Object_References.
I should not be allowed to modify a student just by changing the student ID, I would expect a HTTP 401 Not Authorized :).
I've downloaded and extracted the files. Then I opened it in VS 2013 and built it. Only it failed with 187 errors. The first one, which I suppose it at the route of it all, reads as follows:
"NuGet Package restore failed for project ContosoUniversity: The request was aborted: Could not create SSL/TLS secure channel.."
Hi, I downloaded the code and i builded the solution successfully. But when i run the Update-Database command in the Package Manager Console, i got an error 'Cannot find the object "dbo.Student" because it does not exist or you do not have permissions' .
How can i do?
Yes there are plans, but MVC6 is still changing rapidly, and long tutorial series like the one this is based on are time-consuming to revise, so it's usually not practical while a product is still in preview/beta phases. The tutorial and project most likely won't be updated until the MVC6/EF7 is released and thus relatively stable.
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:
We forgot to re-post the old version somewhere when we updated the sample for MVC 4 EF 5.
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.
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.
