This ModelMetadataProvider for Enums allows binding to dropdowns: http://geekswithblogs.net/nharrison/archive/2013/01/16/simple-way-to-bind-an-enum-to-a-dropdownlist-in.aspx

This would be pretty useful.

A strong part of MVC is its extensibility points. However, if you use an IoC/DI container, there is currently no way to populate its dependencies (similar to how you would a controller via the ControllerFactory).

It should be possible to create bundles during runtime. It's not always possible to know beforehand what scripts/styles pages need. Or it's not practical to create many combinations of scripts/styles.

E.g

~/Views/Shared/_Layout.cshtml
@{
RegisterScript("~/jquery.js");
RegisterScript("~/bootstrap.js");
}

~/Areas/Admin/Views/Shared/_Layout.cshtml
@{
Layout = "~/Views/Shared/_Layout.cshtml";
RegisterScript("~/jquery-ui.js")
}

~/Areas/Admin/Views/Posts/Edit.cshtml
@{
Layout = "~/Areas/Admin/Views/Shared/_Layout.cshtml";
RegisterScript("~/post-edit.js");
RegisterScriptCode("function Foo(){...}");
}

Even the template "Empty" contains many references to unused or obsolete assemblies. Some assemblies or packages included for the future, but this is just confusing and makes clean up a project before starting to develop.

Currently a generic HttpException is thrown when a public action method is not found. I propose throwing a specific ActionMethodNotFound exception that inherits from HttpException. The inheritance should keep the code mostly backwards compatible and the more specific exception would allow easier trapping and translating of these exceptions to 404s without having to do a magic string comparison on the exception message.

pick one and put it in the default templates

Open source the project templates or move them to nuget packages, but let the community fork them or extend them or make it easier to get into the new project dialog... its holding us back.

Refactor the existing controller base class or implement an alternative implementation of the controller base class that does not depend on the httpcontext.. like the web api controller .

See for example this post by Hanselman http://www.hanselman.com/blog/ABackToBasicsCaseStudyImplementingHTTPFileUploadWithASPNETMVCIncludingTestsAndMocks.aspx that shows how troublesome the HttpContext is for testing.

The problem is that you have to stub several layers even if you only want to set a fake value for User for example. It would be great of this could be simplified so that it was possible to Mock/Fake only the properties/objects we need for that test.

I want to be able to get Dependencies from the DependencyResolver through the validationContext parameter of IValidateableObject.Validate(). There is a GetService method and a ServiceContainer but those are a huge pain to get set up.

Support Display(Prompt="...") data annotation in order to render HTML5 placeholder tag with this value

I need to open file from the context menu of right mouse button click on the name of partial view or editorTamplate same as "UserProfileTemplate" in code example behind

@Html.EditorFor(model=>model.Profile, "UserProfileTemplate")

We want better implementation of SimpleMembershipProvider that is not related to Sql server so we can use NoSql databases.
We also want implementation that is not that complex and that reference bunch of dlls (DotNetOAuth is very over complex library to do simple stuff)

I need to change my css and html from visual view of site page, as in chrome developer tools.

in cs or .cshtml file you can get the localized string. For example: ViewRes.Welcome which will return the localized "welcome" text. It would be great if we can do it in any javascript file. Is it possible?

Store/read/initialize data as a tree (Entity Fr.), convert trees to JSON.
View Symfony 1.4 with doctrine nested set, and fixtures.

I don't think I need to explain that one. But just in case we have DropDownListFor, why there's no RadioButtonListFor?
