ASP.NET Dynamic Data Site in Visual Studio 2015 - error "Type is not defined" is global.asax

Question

User794898088 posted

Hello all,

I have been beating my head with this for a while now. Here is my process:

In Visual Studio 2015, I add a new web site to my project, an ASP.NET Dynamic Data web site (Visual Basic).

I then add an ADO.NET Entity Data Model, named "XYZ", and accept the suggestion to place it in the App_Code folder.

I go through the model creation and set up the connection to my SQL Server database. The model generates and looks correct. 

Next, I open Global.asax to uncomment/edit the following line:

DefaultModel.RegisterContext(GetType(XYZEntities), New ContextConfiguration() With {.ScaffoldAllTables = True})

From everything I have read, this should be all I need to load the site. However, it consistently tells me: BC30002 Type 'XYZEntities' is not defined'

I have double-checked the spelling in the Web.config file, and it all lines up.

What do I need to do to fix this?

Thank you in advance.

Hi StoneyB, please check that you are using the Legacy Context in the Entity Data Model the default will be T4 you will need to:

1. Check from T4 to "Legacy Context"
2. Delete the T4 files in you Model for this you will need to expand the edmx file

Hello, and thank you for the reply.

I am trying again, changing the mode from T4 to Legacy ObjectContext. By the T4 files, I assume that you mean the two .tt files, correct?

By doing this, the global.asax line: 

DefaultModel.RegisterContext(GetType(XYZEntities), New ContextConfiguration() With {.ScaffoldAllTables = False})

Still tells me that Type 'XYZEntities' is not defined.

Here is my web.config:

Ok, I think I solved my issue. I have the mode still set on Legacy Object Context, but I tried something new in the Global.asax:

Instead of XYZEntities in the DefaultModel.RegisterContext(GetType(XYZEntities), I tried adding the Namespace before the Entities Class name:

So, that line looks like this: 

DefaultModel.RegisterContext(GetType(XYZModel.XYZEntities), New ContextConfiguration() With {.ScaffoldAllTables = True})

Seems to be working fine now. :)

Glad your sorted, I went for the most common issue first :D
