.net coreasp.net-mvcciis

I used angular .net core 2.2 template to build an application. In localhost working fine, When I host to IIS I'm getting this error. I'm using IIS 10 to host the application.

Error,

HTTP Error 500.21 – Internal Server Error
Handler "aspNetCore" has a bad module "AspNetCoreModuleV2" in its module list

Best Answer

Windows IIS

Solution: Install the hosting bundle.

Reason: Although the SDK normally contains the runtime, however, it seems the SDK installer is not registering the runtime correctly on the server.

Workaround (not recommended):

Change AspNetCoreModuleV2 to AspNetCoreModule inside web.config.

Azure platform hosting

Install the .NET Core runtime extension by selecting Extensions and then installing .NET Core Runtime.

The 2^nd option is the one you want.

In your web.config, make sure these keys exist:

<configuration>
    <system.webServer>
        <validation validateIntegratedModeConfiguration="false"/>
    </system.webServer>
</configuration>

Asp.net-mvc – How to fix: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

It turns out that this is because ASP.Net was not completely installed with IIS even though I checked that box in the "Add Feature" dialog. To fix this, I simply ran the following command at the command prompt

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If I had been on a 32 bit system, it would have looked like the following:

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i

Remeber to run the command prompt as administrator (CTRL+SHIFT+ENTER)
