'Access Denied' Error

Hi

I just downloaded Entity Developer 5.5.105 yesterday and installed the trial. After successfully importing objects from a database, I tried to generate code (C# templates) but without success. The code generation dialog says "Access to Path 'xxxxx' is denied."
I tried several options (folder permissions, UAC - Run as Admin, Compatibility, etc) but no luck.

My machine is an HP Notebook with Intel Core i5 Processor, 8GB DDR3 RAM, 500 GB SATA HDD, running Windows 8 Ultimate x64 with Service Pack (6.2 Build 9200), VS 2012 x64 Update 2, SQL Server 2012 Express x64.

1. Please post here the full call stack.
2. Try removing the ReadOnly attribute manually from the 'xxxxx' file (mentioned in the "Access to Path 'xxxxx' is denied." message).
3. Are you using TFS? Does the problem persist without TFS?

1. I can't see a call stack on the message box. It appears in the Code Generation progress dialog.
2. 'xxxxx' in the message is the path (e.g. C:\User\ThisUser\Desktop\Output), not a file.
3. I'm not using TSF. VS 2012 Ultimate Update 1 only.

I'm getting the same error.

My project uses "NHibernate" (C#), "Data Annotations Metadata" and "Repository And Unit of Work" templates. If I add a "MVC Controller" or "MVC View Advanced" template and try to generate the code from the ED IDE (I'm not using the VS add-in) I get the error "Access to Path 'xxxxx' is denied." where xxxxx is my project folder. As a result, no classes are generated.

The error message appears in the Code Generation progress dialog.

Obviously, ED has access to the project folder :wink:

1. Try giving an access for Everyone to the project folder ('xxxxx' in the message).

2. Please obtain a call stack by attaching from Visual Studio (Debug | Attach to Proccess) to the process of Entity Developer. Before attaching don't forget to make these settings in your Visual Studio: a) in the (Debug | Exceptions) window select Common Language Runtime Exceptions; b) in the (Tools | Options) window, Debugging | General - clear Enable Just My Code (Managed Only).

The folder has full access permissions because it's the project folder and ED can save the project with no errors.

Here is the stack trace:

1. Are you using any custom (modified by you) template? If yes, try disabling it (them). Does it help?
2. Send us a test model (*.edml and *.edps) and specify all templates used in your model. If there are custom templates, send us them as well.

1. No, I don't use any custom templates.
2. I've sended you a test project with a subset of my classes and all of the templates I use.

Thank you for the test model. We have reproduced the error. We will post here when the problem is fixed.

The bug with generating "Access Denied" error when using MVC templates is fixed. We will post here when the corresponding build of Entity Developer is available for download.

The error is now gone but no code is generated for "MVC View Advanced" and "MVC Controller" templates :?

My project uses the following templates:
  • Data Annotations Metadata
  • MVC Controller
  • MVC View Advanced
  • NHibernate
  • Repository And Unit of Work

Please set the "Output > Project" and "Output > Project Folder" properties of the "MVC View Advanced" and "MVC Controller" templates to specify the location of the generated code.

The output folder is set but no output is generated anyway

1. Are you using predefined or custom "MVC View Advanced" and "MVC Controller" templates?
2. Please send us a small test project so that we can reproduce the issue in our environment.
