I’ve an existing MVC3 project that implements a certain functionality, this project has it’s own views, and a separate Database.

now I’m required to use the same functionality inside one of my orchard project,so I thought that I can host this solution in somewhere and view it inside an iframe or something.

Am I thinking right?,
is this the correct step to take in order to achieve this requirement inside Orchard?

to make it more clear, all I need to do is to view this solution and interact with it’s controls and views from a hosting page inside orchard, and the subsequent requests should be handled by my solution in order to hit it’s own data store and get back with the requested data in order to be displayed to the user.

any help would be appreciated.

Update:

thanks for Bertrand Le Roy for his answer, I can now view my solution inside my
orchard website.
I came in to one more HUGE problem, which is that my application can no longer connect to my external database.

I’ve a DB that is hosted in some where else, and I’m using EntityFramework to deal with it.
the problem is that if I put the connection string inside my module web.config, or main orchard web.config, I run into several types of errors like:

“System.Reflection.TargetException: Object does not match target type.“

or

“System.Data.MetadataException: Unable to load the specified metadata resource.”

My question is: How could I pass my connectionstring correctly to my solution, assuming that I’m using Entity framework as my ORM.
Many thanks.

    You will need to put it into a module.

    You will have to move route definitions to a Routes.cs file (look at any existing such file for examples).

    You will also need, in order to access your data store, to opt out of the ambient Orchard transaction around the data access code (using (var scope = new TransactionScope(TransactionScopeOption.Suppress))).

    If you are using dependency injection, you may have some work to move that to the Autofac-based way of doing things in Orchard.

    If you want your work to appear seamlessly in the Orchard admin, you may want to decorate your admin controllers with the Admin attribute. If you want your front-end to use the current theme, you’ll have to add Themed attributes and maybe refactor your views so that they only emit HTML for the content zone instead of for the whole page.

    Add a manifest (module.txt) to your module folder and you should be good to go.
