DynamicData EFProvider 6.0.0 & VB.Net Won't Build

Question

User14123639 posted

Howdy,

I'm trying to generate a simple Dynamic Data website for administration using Visual Studio 2013.  I've followed this link: http://www.c-sharpcorner.com/UploadFile/4b0136/getting-started-with-preview-of-dynamic-data-and-entity-data/ and

1. Created a "Visual Studio 2012 - ASP.Net Dynamic Data Entities Web Application"

2. Using nuget installed the "Microsoft.AspNet.DynamicData.EFProvider"

3. Un-commented the DbContext line in the Global.asax.vb file.  

When I compile I get the following warnings and errors:

Warning    1    Namespace or type specified in the Imports 'System.Data.Objects' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.    ...\SampleApp1\DynamicData\FieldTemplates\ManyToMany.ascx.vb    3    9    SampleApp1

Error    11    Type 'RelatedEnd' is not defined.    ...\SampleApp1\DynamicData\FieldTemplates\ManyToMany_Edit.ascx.vb    79    66    SampleApp1

If I add a reference to System.Data.Entity I get a runtime error on the RegisterContext that says:

"The context type 'SampleApp1.LSICountyEntities' is not supported."

I also tried Uninstalling EF 6.0.0 which is what is installed with the DynamicData EFProvider and installing the current EF 6.1.3 and get the same thing.

Any help would be appreciated.

Hi dblwizard,
Thank you for your post.

I followed the article you provided, it works fine on my side.

As the article said, you could use the code below to RegisterContext instead of Un-commented the default one.

 DefaultModel.RegisterContext(
     new Microsoft.AspNet.DynamicData.ModelProviders.EFDataModelProvider(() => new YourEntities()),
     new ContextConfiguration { ScaffoldAllTables = true });

Hoping my reply could be helpful to you.
Best Regards,

Your comment would imply that you did the article in C# and not in VB.net.  Can you confirm which language you did it in?

Thanks

So is Microsoft abandoning DynamicData?  the 6.0 EFProvider has been out for well over a year with this deficiency and they still haven't addressed it?

Hi dblwizard,

I suggest you create a C# project  to use DynamicData.

Yeah, that doesn't help me a great deal.  I was trying to incorporate this into an existing VB.Net project.  The other developer on this team is a vb.net developer so I need this piece to be vb.

Thanks

I'll look into it for you and ask the Asp.net team if I get nowhere.

User14123639 posted

I got it to work.  There were not a significant amount of changes ... had to remove a bunch of .cs files from the DynamicData sub folders and then using a cs generated project I made the rest of the changes.  It would still be nice if they would publish a VB one or if they are abandoning DynamicData to let us know if they are replacing it with anything.

I think DD will not get any major enhancements with the new MVC 5 that is in the works as there is no support for web forms in there. but you never know what they may come up with :)

Answer 12

User14123639 posted

So if Web Forms only has limited support moving forward is the "Scaffolding" the recommended way to have quick easy access using MVC 5?

Answer 13

User-330204900 posted

Hi I did not say limited support :) it will be fully supported but I can't see any major enhancements for Web Forms going forward.

Answer 14

User14123639 posted

Ok, poor choice of words, there I guess.  That's what I meant by limited ... it would function but nothing new would be released.  In other words it's dieing.  So what is the "recommended" MVC replacement for DynamicData?

Answer 15

User-330204900 posted

Yes that would be true, however I have an open source project I have been working on that I will be releasing soon, been too busy with paying work to get on it but I need to make the time and that has many enhancements to DD.
