Host ASP.Net Core With IIS

Things to know ASP.Net Core run as separate unlike classic ASP.Net which run in process of the IIS Worker Process.

ASP.Net Core run in it’s own web server using highly optimised Kestrel component .

ASP.NET Core applications are standalone Console applications invoked through the dotnet runtime command. It uses AspNetCoreModule to execute the external console.
The AspNetCoreModule loades when the first request comes and then routed to your ASP.NET Core application.

Incoming request int the kernel mode http.sys which routes into IIS.
The request is then forwarded to your ASP.NET Core application on the HTTP port,
Kestrel pushes the request into the ASP.NET Core middleware pipeline which then handles your request and HTTP output is then passed back to the IIS.

How To avoid assembly registration in Web.Config for the Object Data Source

It’s very common to use object data source to bind the grid , formview etc but the problem is Assembly registration in web.config specially in multi server farm.
In order to avoid the registration of your assembly in web.config file just follow two simple steps as mentioned below.


In your UserControl ASCX file add assembly directive

<%@ Assembly Name=”ILX.MKS.Business, Version=, Culture=neutral, PublicKeyToken=123a45b9c456789″ %>


    In object data source give fully qualified type Name like below

    TypeName=”ILX.MKS.Business.UserRegistration, ILX.MKS.Business, Version=, Culture=neutral, PublicKeyToken=123a45b9c456789″

Note: –
There are pros and cons of the above option, this is helpful if you do not want to touch the web.config file, otherside is if you maintain in web.config then  will be central location to maintain
the assembly reference.
