URF vNext (v3.4): ASP.NET v5 RC Web API and pure HTML5/AngularJS (in full TypeScript v1.5) for the presentation layer (no Razor and MVC Controller),AngularJS v2 Beta, EF 7 as VSCode TypeScript & ASP.NET Project - ETA: Q4 - 2015 (inline w/ ASP.NET v5 release schedule)

This framework (over 35K+ downloads) minimizes the surface area of your ORM technology from disseminating in your application. This framework was deliberately designed to be lightweight, small in footprint size, and non-intimidating to extend and maintain.When we say lightweight we really mean lightweight, when using this framework with the Entity Framework provider there are only 10 classes. This lightweight framework will allow you to elegantly, unobtrusively, and easily patternize your applications and systems with Repository, Unit of Work, and Domain Driven Design. To use Generic Repositories or not? The framework allows the freedom of both, generic repositories and the ability to add in your own domain specific repository methods.

Live demo: longle.azurewebsites.net
Live demo is Continuous Integration & Continuous Deployment Site directly from this CodePlex repository.

I modified the T4 templates and use model like

[JsonProperty("id")]
public int Id { get; set; }

I also added ..

var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);


when i call webApi .. whats wrong? Please advice

Created Unassigned: skip page must be after orderBy [1257]

Hi,
in class Repository<TEntity>:
```
internal IQueryable<TEntity> Select(
Expression<Func<TEntity, bool>> filter = null,
Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null,
List<Expression<Func<TEntity, object>>> includes = null,
int? page = null,
int? pageSize = null)
{
IQueryable<TEntity> query = _dbSet;

if (includes != null)
{
query = includes.Aggregate(query, (current, include) => current.Include(include));
}
if (orderBy != null)
{
query = orderBy(query);
}
if (filter != null)
{
query = query.AsExpandable().Where(filter);
}
if (page != null && pageSize != null)
{
query = query.Skip((page.Value - 1)*pageSize.Value).Take(pageSize.Value);
}
return query;
}

```
the " if (page != null && pageSize != null)" should be inside the "if (orderBy != null)" clause.
or if the user tries to skip pages without setting the orderBy, a "System.NotSupportedException" exception will occur.

Regards.

Created Unassigned: Adding Collections [1258]

Hi

I am trying to do some experiment with this framework. Query is working fine. Though I am having some discomfort against exposing the entities while using oData. I don't know what are other ways possible to avoid this.

But my mail problem is, while I am trying to create an order object along with its child collection object OrderDetail and trying to insert, I get an error. It says

"The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: A referential integrity constraint violation occurred: The property value(s) of 'Order.OrderID' on one end of a relationship do not match the property value(s) of 'OrderDetail.OrderID' on the other end."

There are no such example to show how to add object and its collection together. Can you please get back?

Many Thanks

Here are the only two (2) requirements to bootstrap your app and integrate with the framework.

  1. All entities are required to implement IObjectState, we've done this through implementing a base entity class (Entity.cs) which are entities inherit (e.g. Customer.cs).
    Note: we use the EF Power Tools from EF Team, and modified the T4 templates to generate our entities to inherit Entity.cs.
  2. Your DbContext is required to inherit from DataContext.cs.
    Note: we use the EF Power Tools and modified the T4 templates so when the DbContext is generated it already inherits DataContext.
  3. It is recommended you download source code and projects and include them directly into your solution so you can make changes as they are needed for your use cases, after all the framework isextremely lightweight, designed to have a very small footprint and has less than 10 classes.

Optional (recommended) Readings

  • Download the source code, (IMPORTANT:) compile and run all the unit and integration tests, almost all implementation questions can be answered by reviewing them e.g. CustomerRepositoryTests.
  • Review integration test e.g. CustomerRepositoryTest.cs, this is the most comprehensive tests and will run against a database, which illustrates most of the core features of the framework. If time permits review the other integration tests as well, this shouldn't take more than 15 minutes.
  • Review CustomerControllers.cs, this illustrates how to leverage the framework in ASP.NET MVC for all typical CRUD like activity.
  • Review UnityConfig.cs, this illustrates DI/IoC configuration of the framework, most importantly Singleton like behavior that the IDataContext that is bound to the lifecycle of an HttpRequest, this is needed regardless of which brand or type of DI/IoC framework you are using.
  • Leverage the lightweight documentation (below), the documentation is indeed very lightweight and that is deliberate, as is the framework as well.The (non-intimidating) framework has an extremely small footprint - 10 total classes, which includes the Entity Framework provider, with this being said a the framework should also only have lightweight set of documentation that is easy, fast to read and understand.

We have rich discussion and issues forums, 9 times out of 10, most of the questions we receive have already been answered in our discussion/issues forums. If not, start a discussion up, we and/or the community will help. Worse case scenario if question(s), issue(s), or implementation needs Live support, we offer this throughCodementor. This should be a last resort, again because the framework is meant to be easily integrated and consumed. This is an option because we have ran into teams that need live assistance, customization, quick bootstrappiing, guidance with architecture or simply have requirements (e.g. enterprise teams) to use a framework that has support.

Hello, you may not want/need to use the ApplicationUserService, but it is there, and can be extended, if you want to access the ApplicationUser data graph outside of the Identity sub-system. Generally, you would probably not want to do this as it would be easy to corrupt the data that Identity manages directly, but sometimes you may want to. For example, you may want to retrieve a specific view that contains/references the ApplicationUser entity - the ApplicationUserService would be a convenient place to do this - but use with caution!

What compilation errors are you getting?

I see. Well, is there any special reason IApplicationRoleService and IApplicationUserService does not inherits from IService<TEntity> but ApplicationUserService and IApplicationRoleService does from Service<TEntity>?

And that Abl projects. Are they your code? What does mean abl?


I didn't note the errors but at $ and => operators generally. Now its compiles. No problem but sometimes all C#6 features gives error. May be its about the my system.

You are quite right about the interfaces, I have updated the service interfaces to inherit from IService<> - this is what happens if you rely on ReSharper too much!

The 'Abl' namespace references some class libraries and is derived from my company's name. In this application, the libraries really only provide some general purpose helper functions. Feel free to use them, or replace them with your own.

Let me know if you run across any further compilation issues. String interpolation etc. are C# version 6.0 features, so you may need to re-code these if running in an earlier environment.

Hi there. Me again. I wanna ask another question.There is a line in Startup.Auth at end of the ApplicationUserManager method like below
            if (dataProtectionProvider != null)
            {
                manager.UserTokenProvider =
                    new DataProtectorTokenProvider<ApplicationUser, Guid>(
                        dataProtectionProvider.Create("UrfIdentity"));
            }
What the UrfIdentity plain text. Is it can be any text or is it depend to something another? Thank you again.

The MSDN documentation is a little unclear as to the implications of using different string values. From the published examples, the string is set to "ASP.NET Identity", which is arguably more appropriate.

Other people may have more insight into this argument.
