I have an existing ASP.NET MVC 4 project that already uses ServiceStack for REST services, and I just read all about ServiceStack.Razor and would love to move the entire project onto ServiceStack. Right now there is only one controller and view besides the built-in AccountController, and that controller just returns the view and the view is really just HTML; everything else is HTML/CSS/JS + ServiceStack REST.
The only real legacy constraint here is that this new app still needs to make use of SimpleMembership. At present I'm using a custom auth provider to authenticate against SimpleMembership and I would like to be able to continue to do so.
So, what would be the best recommended path to achieve this end? Can I get what I want by modifying my existing project by removing some references, or should I start fresh with an empty ASP.NET app and move the old stuff into it? Can I have SimpleMembership without introducing dependencies that will step all over ServiceStack.Razor?
If you were to start a new solution using only servicestack then MVC would never be there to get in the way.
I use servicestack.razor and love it. It is a lot simpler than MVC in my opinion. Moving everything to the new solution is pretty much going to be copy and paste since what you have works. I wouldn't hesitate and would make the move sooner than later. In the end you are not gaining anything from MVC. You only gain using servicestack. A big deal for me is self-hosting and eventually moving to mono.
This is a question that will have answers based off opinion so I suspect you will receive a few. I have not personally performed such a migration so this is only opinion but is how I would approach it. However, my recommended approach would be:
Retain the existing application/ Given its current simplicity, creating a new app and moving existing items into it seems unnecessary.
You should be able to use your existing auth solution via SimpleMembership and use ServiceStack.Razor. I would proceed as such however it does depend on what other ServiceStack features you may use which could cause conflict. A ServiceStack expert could comment more on this. Even if that did occur, you would be able to work around it relatively easy. At worst, implementing a simple handler would get around almost all issues from an authentication perspective.
Working with different razor engines is relatively easy to do and you can use/enable/disable existing or new build engines via a few lines of code. See here for an example. This should alleviate any concerns around dependencies of other built in or custom engines.
Consider looking at ASp.Net 4.5.1/VS 2013 (since your project is in early days) as it has enhanced membership support and is moving to a more "less dependent" model of components via the Owin stack Asp.Net 4.5.1 and VS 2013. Katana is a microsoft project that also provides some Owin based authentication components see here and here which you could use now and this would remove a lot of dependencies and enable you to migrate other framework with relative ease. Downside is that Katana/Owin has a little ramp up time/learning curve. Again, given your project is in its formative days I would recommend looking into Katana and the ASP.Net vNext stuff as this will make it easier for you and means you dont have to migrate to the new version once it is released.

We have a ASP.NET Web Api project.
A colleague has removed the Microsoft.AspNET references.
We use IIS web hosting.
I would like to use swagger as api help replacement.
But Swagger or the .NET package Swashbuckle/Swagger comes in the CORE with Microsoft asp.net dependencies.
My colleague said we can not use this swagger.
I would like to know what the real problem is (colleague does not really say...) or what the advantage is of a decoupled web api project with asp.net dependecies?
I mean we host on IIS...
I would like to know what the real problem is (colleague does not
really say...)
Not code but, I think this is the first problem. Try to get your "colleague" to explain "why" it's better. (Not just cool code, but also mem/cpu footprint, team-capability-of-take-over, future path, etc.) Good code is maintainable by any qualified developer, not extremely complex and 'understood by only the one'.
what the advantage is of a decoupled web api project with asp.net
dependecies?
Decoupling is a good thing. First, "if you don't use it, don't reference it". To many projects end up having completely useless coupled libraries. Why? Because the "new project" template had them when the project was first created!
In the specific case of Asp.Net core libraries: The current Asp.Net is old, and a new version is on the way. One that will consolidate the knowledge and techniques of "Asp.Net, MVC, WebAPI, OData, OAuth, etc, etc). https://msdn.microsoft.com/en-us/magazine/dn913182.aspx
This means breaking changes are coming.
Not being coupled to the core libraries that are going to change seems like a good idea. If you want to move to this next version you'll have a lot less problems if you're not relying on 'old Asp.Net' functionality.
My colleague said we can not use this swagger.
I think the better way of saying it is; "We will not use anything that tightly couples us to Asp.Net core libraries again since we're decoupling from it".
I am having a little problem in my workplace where we have a IIS 6 server where Orchard (1.7) will not run. We are planning an upgrade but that's going to take some time.
Since we are using this site on IIS6 only to run one particular custom module we wrote for Orchard (basically a MVC module with its own Controllers/Actions etc.) I was thinking that a temporary solution could be to rip that module out of Orchard and run it independently.
Of course this extraction needs to take into account how many ties I have with the framework. I was wondering if there is some kind of guide to perform this and if there is something I need to take specially into account.
I am using the Users in Orchard so I would probably have to rewrite some users code. I am also using the Authorizer, which again may mean I need to re-wire something else.
It seems like a daunting job so I am looking for some quick tips on how to proceed if you know any.
Thanks a lot!
It all depends on what components you actually use within your module.
Hard to write any tutorial on this, really.
Regarding Orchard.Users - you could drop all related code usages and rely on the default ASP.NET roles-based authentication/authorization model.
If dependency injection is what you want to keep, then you need to integrate it yourself (for Autofac, but other DI containers will also work). Feel free to copy and change any Orchard components that you use, stripping the unneeded code.
In my opinion the hardest thing to strip out and replace would be any code that relies on content items - hope you don't have it. Rewriting this pieces sounds like an overkill. But if you just use IRepository, going for plain NHibernate or EF instead should be quite easy.
The project I’m working on is revamping an existing web portal.
Migration from the old controls (Infragistics) to a new suite (Telerik) is part of the revamp.
Would you recommend to keep the old Visual studio project and put the new controls in or starting a new VS project altogether?
It depends on how much you are using the third party controls and what portion of your site it is. If it is a small portion it may be better to continue with the existing project. If you have very heavy usage of the third party controls that you are removing on each page a rewrite may be easier.
If you are looking at possibly rewriting using a new project you may also want to consider the technology that you are using as well. For example if you were using ASP.NET Web Forms before, maybe it would make sense to use ASP.NET MVC now.
I believe the best answer to your question is that you need to evaluate what you are using and the amount of work that each approach will require and determine what is best for your specific scenario.
We have an app written in Objective C. It uses CoreData, RestKit, about 10 viewcontrollers.
We would like to migrate it to Xamarin (so we can target Android and Windows).
I was hoping there was a way to bind the current code to a Xamarin solution and kind of rewrite features step by step within Xamarin (eg: replacing a viewcontroller at a time, and at the end replacing RestKit+CoreData, by SQLite + ServiceStack).
I am aware of the binding to Objective C option that they provide, however, it doesn't look to be the appropriate fit for this (way too complex, probably easier to rewrite the app from scratch).
Is there a way to migrate our current project to Xamarin so we can convert? or do we start from scratch?
Thanks.
Options:
Migrate full project - no;
Automatically create binding for libraries, rewrite business-code, UI-code - yes;
Rewrite from scratch using .Net/Mono classes - yes.
If code size is relatively small, you should rewrite the whole app. Moreover, thus you could have a chance to separate business-logic from UI code and tools libraries (RestKit, CoreData). In perspective, that code will be more reliable and cross-platformish.
This tool can help. It does Obj-c to C# translation (some manual cleanup required):
Automagical
Quite probably, a re-write, from scratch. One thing to keep in mind, if your back-end is .net.. and you are using DTO's.. like with AutoMapper from Entity Framework objects.. you'll be able to re-use those DTO objects on your mobile side with Xamarin. If you are using OData, I'm not sure if this is still a problem, but Xamarin studio wasn't generating OData service clients. So you had to generate them in Visual Studio, then take the generated client code and throw them into your Mobile projects.
sqllite-net is awesome. I've never had any problems with it.
https://github.com/praeclarum/sqlite-net
I currently have a project, with DTO Objects from an Azure WCF service, that I push directly down into SQLLite objects on IOS and Android with Xamarin. I use RestSharp, rather than Service Stack. I should probably go learn the difference.
If you are looking to use SQLCipher from the Component store, to encrypt your sqllite db locally on your device (Good advice to do so), you should be aware that there is an issue in android.. going to 2.2 or 2.3 with SQLCipher. Works for ICS and above though, if I remember right.
Just be careful on your security implementation for allowing clients to connect. I want to say.. don't take too much advice.. and don't take too little either. : )
Can existing .net application(in C#) be converted to MonoDroid? or
Can we port an existing .NET web app to Android using MonoDroid?
MonoDroid is intended to allow you to develop applications in C# as opposed to Java; not as a means to drop an existing application into place.
You asked about a web app, but I'm assuming you mean an ASP.NET web app, which wouldn't map to the Android API, and couldn't simply be copied over. Even taking your HTML and dropping it into something like Titanium would still require a lot of JS tweaking to make it work.
I have a feeling you're looking at a re-write. Maybe if you can provide more details (is this an ASP.NET app, etc.), I could give a better answer.
Yes no problem. But it wouldn't be an automatic process, nor a particularly simple one. All the UI elements, persistence stuff and so on (the platform specific parts of your application) will need to be redone. Depending on your app, and how it is written, this may be a major part, or a relatively small one. The more corners that were cut originally, the more it will cost to port over.
In addition to Tom's answer, I would say it has some limitations(link 1 and link 2) . I blogged some other interesting moments here.
Here is a good example of cross-platform mobile application (monoDroid, monoTouch, WP7).
