Extendable packages pack for simplifying Bootstrap markup in your ASP.MVC projects.

• BootstrapMvc.Core - core library, containing base clasess only;
• BootstrapMvc.Bootstrap3 - helper classes for Bootstrap 3.3 (not complete at this moment), not bound to any MVC version;
• BootstrapMvc.Bootstrap4 - helper classes for Bootstrap 4 (alpha.3, not complete at this moment), not bound to any MVC version;
• BootstrapMvc.Mvc5 - classes for integrating with ASP.MVC5 infrastructure;
• BootstrapMvc.Mvc6 - classes for integrating with ASP.NET Core / MVC6 infrastructure;
• BootstrapMvc.Bootstrap3Mvc5 - 'use-this' package (with correct dependencies) for using in your MVC5 projects.
• BootstrapMvc.Bootstrap3Mvc6 - 'use-this' package (with correct dependencies) for using with Bootstrap 3 in your ASP.NET Core / MVC6 projects.
• BootstrapMvc.Bootstrap4Mvc6 - 'use-this' package (with correct dependencies) for using with Bootstrap 4 in your ASP.NET Core / MVC6 projects.

1. Library decomposition - allows creating different packages for different Bootstrap and/or Mvc versions with minimal code duplicating and without unneeded dependencies;
2. Highly extendable - you can add helper methods to modify/extend existing classes, or add new classes, directly in your MVC project, not in package sources;
3. Fluent - write short and efficient code;
4. TextWriter-based - internally, all HTML is written directry to TextWriter-s, minimizing String allocation and concatenation;
5. Open source - fork it, extend it, use it!

Just one sample - input form. Do you remember how much markup you should write? Now you can:

using (var form = Bootstrap.BeginFormFormType.Horizontal))
{
    using (Bootstrap.BeginFormFieldset("Fieldset one"))
    {
        @Bootstrap.FormGroupFor(m => m.StringField)
            .Label("Label 1")
            .Control(Bootstrap.Input().Placeholder("placeholder text"))
    }
    using (form.BeginFieldset("Fieldset two"))
    {
        @form.GroupFor(m => m.IntegerField, "Label 2")
            .Control(Bootstrap.InputInt().Size(0, 3, 3, 3, 3))
        @form.GroupFor(m => m.BooleanField)
            .Control(Bootstrap.Checkbox("checkbox text"))
    }
    using (form.Group().BeginContent())
    {
        @Bootstrap.Button(ButtonType.SuccessGreen, "Save")
        @Bootstrap.Button(ButtonType.SecondaryWhite, "Cancel").Href("/list")
    }
}

And you got this:

Install BootstrapMvc.Bootstrap3Mvc5 package from NuGet to your ASP.MVC5 project.

Modify your Views\Web.config file (and all Areas\<Area>\Views\Web.config too), replace base class for views (in <system.web.webPages.razor> section), instead:

<pages pageBaseType="System.Web.Mvc.WebViewPage">

write

<pages pageBaseType="BootstrapMvc.Core.BootstrapViewPage">

And add one more namespace to namespaces list:

<add namespace="BootstrapMvc" />

Clean and Rebuild you project to activate changes and activate intellisence. Rarely, a Visual Studio restart also needed.

"dependencies": {
    ...
    "BootstrapMvc.Bootstrap3Mvc6": "2.3.0"
}

"dependencies": {
    ...
    "BootstrapMvc.Bootstrap4Mvc6": "1.0.0-*"
}

RTM build of ASP.NET Core / MVC6 is supported.

Add two lines to Views\_ViewImports.cshtml file (create it if not exists):

@using BootstrapMvc
@inject BootstrapMvc.Mvc6.BootstrapHelper<TModel> Bootstrap

Append to ConfigureServices() method in Startup.cs file:

services.AddTransient(typeof(BootstrapMvc.Mvc6.BootstrapHelper<>));
