I've inherited an MVC3 project that has a large number of ASPX views that I would like to convert to Razor. This question => Aspx to Razor syntax converter? is similar to mine, and it helped me find a bunch of options for converting the views themselves, but I'm unclear on the steps I need to take in addition to converting the views.
The first known limitation of Telerik's razor-converter is "The tool only works with views and does not deal with the project structure and master pages". This tool claims to be able to convert master pages as well, but it doesn't look like anybody beyond the developer has ever used it.
I think these are the steps I need to take:
Use a utility to convert the views
Convert the master pages manually (how do I do this?)
Modify the project structure (what needs to be modified?)
Delete the ASPX files
Test the application (any specific gotchas I should look out for?)
Are these the right steps? Can you help me with my questions on steps 2 and 3?
I have only tried this on one solution and the actual conversion did a fairly good job. I downloaded the Telerik converter project, compiled it, and then converted my projects using these command lines:
aspx2razor C:\Development\MyProject\MyWebProject\*.ascx C:\Development\MyProject\MyWebProject -r
aspx2razor C:\Development\MyProject\MyWebProject\*.aspx C:\Development\MyProject\MyWebProject -r
aspx2razor C:\Development\MyProject\MyWebProject\*.master C:\Development\MyProject\MyWebProject -r
I only needed to go back to add an #include for a namespace here and there, and to add a few parenthesis to force the Razor view engine to recognize my inline code properly. This was also a fairly simple solution, so YMMV. But even if it converted 80-90% of your views successfully, it's that much less manual work which you would have to perform yourself. From here, you could also create a _ViewStart.cshtml file and make a few minor adjustments to take advantage of Razor-specific layout features. (Check out Scott Gu's post on it here: http://weblogs.asp.net/scottgu/archive/2010/10/22/asp-net-mvc-3-layouts.aspx)
The big issue I had was trying to reconcile the file changes with source control. Since the classic MVC view engine uses .aspx, .ascx, and .master extensions, I had to manually add the .cshtml files to my MVC web project and source control then remove the old versions. It wasn't difficult, just time-consuming.
In addition, you may need to add all of the necessary web.config entries to support the Razor view engine as well if your project was created using MVC 1 or 2. Projects created with MVC 3 should already have these entries in place, even if it was not originally created as a Razor site.

I am using MVC 4.I have designed a webpage in Dreamweaver and then tried to convert it as a razor page. I wanted to view it in a browser, without using Visual Studio. I have heard that a Razor page can be edited using a notepad.
Please help, I am comfortable designing pages in Dreamweaver, than in Visual Studio.
If I understand you correctly you have a HTML design (created in whichever tool you prefer) and you wish to create an MVC website out of this. You have experience in ASP.NET Webforms.
Primarily to creating anything I would follow the topics covered in the ASP.NET MVC tutorials of MVC itself. It's not about "default templates" it's about understanding what builds your final output. Layouts, partial renderings etc...
See http://www.asp.net/mvc
PS: Ask yourself: Is MVC the right choice for my solution? (because I get the feeling everyone just wants to use MVC and doesn't think about what it is and why you should or shouldn't use it...)
If you dont't want to use default template then you can include your css files you created in Content folder. In shared folder which is located inside Views folder you can create the your customized layout which uses the css that you included in Content folder. And you can then include these layout in the views you later create inside shared folder of Views.
You can explore yourself by installing twitter.bootstrap.mvc4.sample from package manager console and see how your project changes.
This package changes your default layout to different layout, which is pretty cool.
Hope you can get idea of what is done and how you include your own layout from this above mentioned package.
ok, i know there are a lot of posts online that specify how to do iterations with MVC.
my question is slightly different. when i used to do iterations using WebForms, i was creating one thing only and finishing that one thing till the end which was including the deployment on production.
for example, i was creating a webpage and deploying it, then i create the second page and deploy it. so .dll files were added to my bin folder while the previous dlls remain untouched. at the other hand, when i was making a change latter on, there was this one file that needed to be replaced on production.
now here is the question, how can i acheive the same thing in mvc? beause it just doesn't deploy each page into an individual dll. each time that i add something i have to redeploy the application dll which is not really wise! i played around with deployment options in visual studio but no luck!
There is nothing preventing you from putting controllers and other code in separate assemblies and dropping them in an existing application. Like any ASP.NET based application an MVC application will automatically restart if you add or modify any file in the bin folder or modify web.config.
If you're using Razor you can use RazorGenerator to generate code for your views and compile them into the same assembly.
You may need to write some additional logic though to get routes, model binders etc. wired up correctly.
For a more structures approach to compose the application of separate modules, you may want to look into portable areas. This is an extension to ASP.NET MVC that allows you to package the entire module (including views, css, js etc.) into a single assembly.
First thing, you have to work on the title of the post, it does not match the content of the post.
In asp.net mvc u can choose to deploy only what changed. I.e. If you only changed the .cshtml file, then you can just replace it with the file in production. However if you change any controller class (C#/Vb code), then you will have to upload the web project dll file too so that this new changes are available in the production env
Here is what I want to achieve, I want to separate AREAs of ASP.NET MVC as pure single DLL.
Blog.DLL
Forums.DLL
FAQ.DLL
Each of them are individual ASP.NET MVC Area, with its own default CSHTML or ASPX pages. Installing, migrating and maintaining lots of pages including resources, javascripts and so on are real pain for long run. As most of these will hardly change.
My final website will be like this.
\MvcApplication
\bin
\MvcApplication.bin
\Blog.dll
\Forums.dll
\Controllers
\..
\Models
\..
\Views
\..
\Global.asax
\Web.config
Without adding any thing, just dropping Blog.dll, my application should support /blog and all its pages. If I want to customize something, than I can add area, and add only cshtml pages..
\MvcApplication
\bin
\MvcApplication.bin
\Blog.dll
\Forums.dll
\Areas
\Blog
\Views
\Shared
\BlogLayout.cshtml <-- this will override the look
\Controllers
\..
\Models
\..
\Views
\..
\Global.asax
\Web.config
This will help in reusing ASP.NET Area Plugins, by simply dropping the dll in bin folder. However web.config may require some changes, but most likely we will save configure values in database and only thing needed will be "Entity Framework connection string" in web.config.
My challenges (Questions)
Is it possible? It sure looks to me, but will there be any reflection/permission issues?
How do I include cshtml/aspx views within one DLL? Probably compiled versions? I have seen couple of text template based View Engines on codeplex but I am little confused on how to actually use them.
And how do I get ViewEngine to first check if physical directory file exists or not and then look into cshtml/aspx within the dll itself as resource file?
You may take a look at the following article which illustrates how a custom VirtualPathProvider could be used in order to retrieve Razor views that are embedded into separate assemblies as resources.
Maybe worth looking at portable areas from mvccontrib. I haven't used them since MVC 2, but found the following SO question by someone having some problems using them with MVC 3, with some possible solutions: ASP.NET MVC 3, Razor Views, and Portable Areas
MvcCodeRouting supports what you want, plus many other cool stuff. Check out this post about ASP.NET MVC Plugins.
I am trying to create a .Net Library with few Controllers, and i want to reuse them in Multiple web projects.
I'm half way through, But problem i'm getting is , Whenever i add the library to the new web project , i need to copy all corresponding view files separately to the new project. Whenever i update the library, i need to repeat the steps again.
Is there any way , i can embed View files inside dll as resource , and pass it to "View()" function as an embedded resource.
What i want to achieve is , I want to put controller and corresponding views inside single dll file, so that i can easily distribute/manage the library as a single dll file
( Oneway i already found , is creating custom view class with IView Interface and Render the output directly by writing to HTML Output Writer, But i prefer to use the View file.)
Phil Haack just posted a blog post a few days ago that would probably help you; He's using a database to store the views and ruby to process them, but I would think you could take his prototype and make it work for views stored in a separate assembly fairly easily.
Just a quick glance through the code and I think the magic sauce is going to be implementing VirtualPathProviderViewEngine (See the "RubyViewEngine" class for example) and inserting your ViewEngine into ViewEngines.Engines Collection (see Global.asax.cs).
You can probably use a VirtualPathProvider for this.
The WebFormView type eventually calls BuildManager.CreateInstanceFromVirtualPath. There is not an overload or other function in BuildManager to take input from a stream instead of from a virtual path. Therefore, if you do not want to implement IView yourself, you will need to actually unpack the files to disk so that they can be compiled by BuildManager. You could still distribute your DLL as a single file, but the aspx files need to be produced in order for BuildManager to compile them. See BuildManager help for details.
Check out the ASP.NET MVC View Engine using VB.NET XML Literals project on CodePlex http://vbmvc.codeplex.com
It is a custom view engine originally conceived of by Dmitry Robsman, who is a PUM for ASP.NET at Microsoft. Each view is a VB.NET class and the Namespace (instead of file path) is used to connect Views to Controllers. It's fairly straight forward to copy the content of your ASPX view files into the XML literals in these VB classes. And as classes, they are compiled into the assembly without any extra effort.
If your controllers are C#, then most likely you'd end up with 2 DLLs, but Scott Hanselman has a blog post on getting C# and VB to live together in the same assembly. http://www.hanselman.com/blog/MixingLanguagesInASingleAssemblyInVisualStudioSeamlesslyWithILMergeAndMSBuild.aspx
Take a gander over to codeplex and have a look at the Managed Extensibility Framework
Once your done there...
See what Maarten Balliauw has to say about ASP.NET MVC and the Managed Extensibility Framework (MEF)
Trying to create a MVC User Control in the Release Candidate and I can't see to make one with a codebehind file. The same is true for MVC View pages.
Creating Views in the Beta would produce codebehinds...am I missing something?
Code behind kind of defeats the purpose of the MVC Framework. Functionality should be kept separate from the view, the MVC team felt that code behind pages went against this ideology and therefore removed them.
Your can create a custom helper method to create your control. Also I'm not sure if MVC has view components (Monorail/Castle) but that could be an option as well.
From ScottGu's Blog post:
*Views without Code-Behind Files
Based on feedback we’ve changed view-templates to not have a code-behind file by default. This change helps reinforce the purpose of views in a MVC application (which are intended to be purely about rendering and to not contain any non-rendering related code), and for most people eliminates unused files in the project.
The RC build now adds C# and VB syntax support for inheriting view templates from base classes that use generics. For example, below we are using this with the Edit.aspx view template – whose “inherits” attribute derives from the ViewPage type:
One nice benefit of not using a code-behind file is that you'll now get immediate intellisense within view template files when you add them to the project. With previous builds you had to do a build/compile immediately after creating a view in order to get code intellisense within it. The RC makes the workflow of adding and immediately editing a view compile-free and much more seamless.
Important: If you are upgrading a ASP.NET MVC project that was created with an earlier build make sure to follow the steps in the release notes – the web.config file under the \Views directory needs to be updated with some settings in order for the above generics based syntax to work.*
I answered this question here:
How to add a Code-behind page to a Partial View
Seems this wasn't particularly tricky, and is quite do-able
This answer worked for a Partial 'ViewUserControl' but the same should apply
Ok.
First: Add a Class file with the convention of .cs (i.e. view.ascx.cs)
Second: Add "using System.Web.Mvc;" to the class
Third: Change the Class to Inherit from "ViewUserControl<>"
Fourth: Add the following to the View's header:
CodeBehind="View.ascx.cs" Inherits="Project.Views.Shared.View"
Fifthly: Copy the files out of the solution and drag back in to reassociate the two together
Note: For this to work with a Normal MVC View you just need to inherit the class from "ViewPage"
The whole idea for ASP.Net-mvc was to get rid of the codebehind files...thats why asp web controls didnt matter that most didn't work.But with the changes of getting rid of the code behind comes with a different programming style..The idea is codebehind files are EVIL:
http://stevesmithblog.com/blog/codebehind-files-in-asp-net-mvc-are-evil/
the whole idea is to make sure people remember they are using asp.Net-mvc and not asp.et web pages. take alook at this link ,it explains it a little better:
http://blog.lozanotek.com/archive/2008/10/20/Visual_Studio_Templates_for_MVC_Views_without_Codebehind_Files.aspx
I think this tutorial is what you are asking.. but not really sure what you want..
