Creating a Generic Entity Framework 4.0 Repository

With .NET 4.0 right around the corner, I thought it would be cool to download Visual Studio 2010 beta 2 and start playing around with the next release of Entity Framework.

The initial release of Entity Framework came with a great deal of criticism. To make matters worse, there was a large uproar when it was rumored that Microsoft would be abandoning LINQ to SQL, in favor of Entity Framework. This was because, at the time, many developers felt Entity Framework was an inferior technology to LINQ to SQL. To set things right, Microsoft proactively moved forward with improving Entity Framework, in time for the 4.0 release of the .NET Framework. This is good news because my initial impressions, so far, have been nothing but positive.

A Generic Dialog ViewModel

I worked on a wpf viewmodel for dialogs, because it seemed strange to me that you needed for instance windows forms dialogs to open or save files in wpf. So I set about creating my own wpf dialogs. After creating the dialog viewmodels there still remained a small issue with the library and also I didn't have much time to write an article about it. I however published the library containing the viewmodels for dialogs with another article on my blog

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?


Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont

Pure C++: Reflecting on Generic Types


A funny thing happened to templates on their way to the common language runtime (CLR)-they lost their {type} identity. This is analogous to what happens with macros under native programs. Just as the C/C++ compilers have no awareness of macro preprocessor expansions, the CLR has no awareness of template instantiations.

Pure C++: Invoking Generic or Function Templates


As I promised last time, in this month's column I'll walk through the process of defining and invoking a generic or template function under C++\CLI. A function template or a generic function begins with the template or generic keyword followed by its parameter list.

Pure C++: Generic Programming: Template Specialization


As I discussed in my last column, a param-eterized type that does more than simple storage and retrieval is constrained as to the acceptable types that may be safely bound to it (see Pure C++: CLR Generics Versus C++ Templates.

Pure C++: Generic Programming Under .NET


Visual Studio® 2005 brings the type parameter model of generic programming to the Microsoft® . NET Framework. Parameterized types are, of course, standard fare for C++ programmers. So, for those who are unfamiliar with them, I'll give a brief introduction to generic programming in my next few columns.

Generic Repository in EF4 and MVC



I created a generic repository for a EF4 context in MyProj.Domain.

Now I have services with methods like FindById, FindByUsername that use the repositories.

My controllers use these services. 

Should I do the Mapping from Entities to View Models inside the services or in the controller?

The problem is for example, I might have UserEditViewModel and UserSignInViewModel.

In both cases I would need FindById.

So I might use UserService.FindById(id) in the controller and then map it to UserEditViewModel or UserSignInViewModel.

Or the other way around is to have two methods FindById in the service one returning UserEditViewModel and the other UserSignInViewModel.

I tend to do the mapping in the controller using AutoMapper so it is only a code line but I am not sure if this is the correct way.
