This page is used for taking my notes during my daily programming works. It helps myself, of course, on quick references before searching. And I am glad if you find it useful.

ASP.NET MVC

  • Ignore a path for downloads (or accessing static files in ASP.NET MVC Web Application)

    Add a line below to the RegisterRoutes() method in the RouteConfig.cs file.

    routes.IgnoreRoute("Downloads/*");

    or to ignore all

    routes.IgnoreRoute("");

    Full class

    public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        // allow to access static files under /Downloads/*.* = no routing this path to Controller in MVC
        routes.IgnoreRoute("Downloads/*");
        //routes.IgnoreRoute("");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

Newtonsoft Json.NET

  • JToken

    Link: https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Linq_JToken.htm

    The JToken hierarchy looks like this:

    JToken              - abstract base class     
    JContainer      - abstract base class of JTokens that can contain other JTokens
        JArray      - represents a JSON array (contains an ordered list of JTokens)
        JObject     - represents a JSON object (contains a collection of JProperties)
        JProperty   - represents a JSON property (a name/JToken pair inside a JObject)
    JValue          - represents a primitive JSON value (string, number, boolean, null)

EF & EF Core

  • Differences in connection string

    2 flashes \\ in connection string Server=(LocalDB)\\MSSQLLocalDB in appsettings.json file

    {
    "ConnectionStrings": 
    {
        "DefaultConnection": "Server=(LocalDB)\\MSSQLLocalDB;Database=AppDb;Trusted_Connection=True;"
    }
}

    but ONLY 1 flash \ in connection string Server=(LocalDB)\MSSQLLocalDB in dotnet ef dbcontext scaffold command

    dotnet ef dbcontext scaffold "Server=(LocalDB)\MSSQLLocalDB;Database=AppDb;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -o Models
