Utility library providing useful helpers, formatters and extensions for ASP.NET Core

NuGet Pre Release

PM> install-package westwind.aspnetcore

or the dotnet command line:

dotnet add package westwind.aspnetcore


MVC Functionality
  • BaseController and BaseViewModel implementation
    A common base controller class that adds support for an auto-initialized BaseViewModel from which other VMs can inherit. Allows for automatic initialization of common features like ErrorDisplay and Base View models.

  • ViewRenderer
    Render Razor/MVC view output to a string using a controller context.

  • FormVariable to Object Instance Binder
    Request.Form unbind routine that allows you to unbind form variables into an existing object only updating properties that are are available in the request form context.

  • AppUser ClaimsPrincipal and Cookie Authentication Helper
    A AppUser class that wraps a ClaimsPrincipal and makes it easier to add and retrieve claims as well as easily login and logout all from a single helper object.

  • Bootstrap Alert ErrorDisplay Tag Helper and Controller Support Feature
    In most MVC applications you need some sort of error display and this ErrorDisplay TagHelper makes it quick easy to display an Alert box from a custom ErrorDisplayModel input. Helper methods like ShowError() or ShowInfo() on BaseViewModel make it very easy to display error and informational messages on pages.

Api Functionality
  • Api Error Handling Filter
    A custom API error filter implementation that returns API responses on exceptions. Also provides a standardized ApiExecption class that can be used to force responses with specific HTTP response codes.

  • Api Base Response Object
    ApiResponse base class that can be used to return consistent API results that include error status, error message, status code as well as the actual data. Both typed and untyped versions.

  • RawRequest Body String Formatter
    API formatter that allows for receiving raw non-json content to string and byte[] parameters, which otherwise isn't supported by MVC's API implementation. More info in blog post.

  • User Token Manager
    A database driven token manager that can create, store, validate and manage the life time of short lived generated tokens. Useful for creating tokens that are assigned after an initial authentication and then used for API access.

General ASP.NET Core
  • Custom Headers Middleware
    Allows adding and removing of HTTP headers to every request using middleware configuration.

  • HttpRequest Extensions

    • GetBodyStringAsync() and GetRawBodyBytesAsync() - retrieve raw non-JSON content
    • MapPath() - Map virtual path to physical path on disk
    • Params() - Return an item from Form, Query or Session collections.
  • DataProtector Wrapper
    Helper to make it easier to use the DataProtector API to create secure tokens.

  • UserState Helper
    The UserState object greatly simplifies working with auth 'cached' token data more easily by storing a single value in a user claim or forms auth ticket that can be easily restored into an typed object. The class supports easily serialization and auto-loading from Claims. Can be extended by subclassing and adding your own values.
