I’m using Mono 2.4 on the Ubiquity web hosting service.
I created a simple MVC tutioal applciation, linked here, and verified that it worked using all Microsoft tools.
Next, the application was updated to point to a MySQL server database running on my Ubiquity host. The application works great on a Microsoft based machine.
Now, I am trying to deploy the application to the mono server on Ubiquity.
I set System.Web.MVC so it will CopyLocal=true.
I deployed the application to the mono server.
I get this error:
Description: Error parsing a resource required to service this request. Review your source file and modify it to fix this error.
Parser Error Message: Assembly System.Data.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 not found
Version information: Mono Version: 2.0.50727.1433; ASP.NET Version: 2.0.50727.1433
I am guessing the problem could be…
A) The Entity framework is not supported in mono. I need to use something other than the Microsoft Data Entity Framework.
B) The public key token for the mono version of System.Data.Entity is not “b77a5c561934e089”.
C) There is something else going on.
I tried setting CopyLocal=true for the System.Entity.Data dll. Thus, the Microsoft version of the DLL deployed to my mono server. I have doubts that this is legal. At any rate, that only produced the following error:
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
Question
Can somebody confirm that it is possible to use the Microsoft Entity Framework on Mono? I am probably going to migrate away from the Microsoft Entity Framework, per this comment in the Microsoft MVC tutorial linked above..
“The ASP.NET MVC framework is not tied to the Microsoft Entity Framework. You can create >your database model classes by taking advantage of a variety of Object Relational Mapping >(OR/M) tools including LINQ to SQL, Subsonic, and NHibernate.”
However, for the sake of consistency, I would like to use the Microsoft Entity Framework on mono if that is possible.
You should set CopyLocal = true for the System.Data.Entity assembly as well. You noted that you copied System.Web.MVC local, but never mentioned that you copied System.Data.Entity locally. You might also need to copy local any of the assemblies that System.Data.Entity depends upon that are not part of Mono.
