This is a Custom Tool for Visual Studio that allows processing Razor files at design time instead of runtime, allowing them to be built into an assembly for simpler reuse and distribution.

Note that this tool currently only supports C#. VB support could probably be done if someone wants to help out with it!

Installation instructions

It’s on the VS extension gallery, so install it from there. It’s called “Razor Generator” (not to be confused with “Razor Single File Generator for MVC”).

Generator Types

  • MvcHelper: Creates a static type that is best suited for writing Mvc specific helper methods.
  • MvcView: Create a WebViewPage which allows the use of precompiled MVC views.
  • WebPage: Creates a WebPage type that can be used as WebPages Application Part (such as _Admin and RazorDebugger).
  • WebPagesHelper: Creates a HelperPage type that is suited for precompiling and distributing WebPages helper.
  • Template: Generator based on T4 preprocessed template.

Usage in an MVC app

  • Install the 'RazorGenerator.Mvc' package, which registers a special view engine
  • Go to an MVC Razor view's property and set the Custom Tool to RazorGenerator
  • Optionally specify a value for Custom Tool Namespace to specify a namespace for the generated file. The project namespace is used by default.
  • Optionally specify one of the generators in the first line of your Razor file. A generator declaration line looks like this: @* Generator: MvcHelper *@. If you don't specify this, a generator is picked based on convention (e.g. files under Views are treated as MvcViews) NOTE: The selection has other criteria such as detecting "Helper" in the filename and choosing WebPagesHelper for those.
  • You'll see a generated .cs file under the .cshtml file, which will be used at runtime instead of the .cshtml file
  • You can also go to the nuget Package Manager Console and run Enable-RazorGenerator to enable the Custom Tool on all the views.
  • And to cause all the views to be regenerated, go to the nuget Package Manager Console and run Redo-RazorGenerator. This is useful when you update the generator package and it needs to generate different code.

Usage in a View Library

If you need to create a separate library for your precompiled MVC views, the best approach is to actually create an MVC project for that library, instead of a library project. You'll never actually run it as an Mvc app, but the fact that it comes with the right set of config files allows intellisense and other things to work a lot better than in a library project.

You can then add a reference to that 'MVC View project' from your real MVC app.

And note that you need to install the 'RazorGenerator.Mvc' package into the library, not the main MVC app.

See https://github.com/davidebbo/MvcApplicationRazorGeneratorSeparateLibrary for a sample.

Special Razor directives

These directives go into a Razor comment at the top of a cshtml file. Multiple directives are simply whitespace-separated within the comment:

@* Generator: Template  GeneratePrettyNames : true *@

You can also have them on separate lines for clarity but must remain part of the same comment, e.g:

@* Generator: Template  
   GeneratePrettyNames : true *@

Generator type

@* Generator: MvcHelper *@

See above for list of valid values.

disabling line pragmas

@* DisableLinePragmas: true *@

Changing type visiblity

@* TypeVisibility: internal *@

Using absolute paths in line pragmas instead of relative

@* GenerateAbsolutePathLinePragmas: true *@

Overriding the generated namespace

@* Namespace: SomeNamespace *@

Adding a suffix to the generated class name (can be useful to avoid some conflicts)

@* ClassSuffix: _ *@

Generate namespaces and class names based on file name instead of the Razor default

@* GeneratePrettyNames : true *@

Trimming leading underscores in generated class names

@* TrimLeadingUnderscores : true *@

Adding generic type parameters

@* Generator: Template GenericParameters: TKey, TValue *@

Add ExcludeForCodeCoverageAttribute to generated files

@* ExcludeForCodeCoverage : true *@

Import additional namespaces during view precompilation

@* Imports: Microsoft.Web.Mvc, MvcContrib, This.WebSite, This.WebSite.Html, HtmlHelpers.BeginCollectionItem *@

Set BaseType during view precompilation

@* BaseType: This.ViewPageBase *@

As an alternative, you can create a file named razorgenerator.directives in the Views folder to apply directives globally. e.g. it could contain:

GeneratePrettyNames: true  GenerateAbsolutePathLinePragmas: true
