Answer 1

Install .Net Core 2.2 run-time bundle on hosting machine.

Or

Publish your project as self-contained.

Answer 2

I had this problem just a second ago. I replaced my code part in web.config with this.

OLD PART:

<handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" 
        resourceType="Unspecified" />
</handlers>

NEW PART:

<handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" 
        resourceType="Unspecified" />
</handlers>

Answer 3

There are a couple ways you can fix this:

1. Install the latest .NET Core Runtime
2. Inspect the applicationhost.config file used by your IIS. You should have the following entry in its appropriate locations:

<configuration>
    <system.webServer>
        ...
        <globalModules>
            ...
            <add name="AspNetCoreModuleV2" image="%IIS_BIN%\Asp.Net Core Module\V2\aspnetcorev2.dll" />
        </globalModules>
    </system.webServer>
    ...
    <location path="" overrideMode="Allow">
        <system.webServer>
            <modules>
                ...
                <add name="AspNetCoreModuleV2" lockItem="true" />
            </modules>
        </system.webServer>
    </location>
</configuration>

Just make sure you actually have the file for aspnetcorev2.dll in your IIS bin directory.

Answer 4

Here is what worked for me:

1. Check your applicationhost.config file and ensure you have the following entry in your globalModules section.

<add name="AspNetCoreModuleV2" image="%ProgramFiles%\IIS\Asp.Net Core Module\V2\aspnetcorev2.dll" />

2. Open IIS Manager, go to Modules. If AspNetCoreModuleV2 is not listed, click "Configure Native Modules..." and select "AspNetCoreModuleV2" and click OK to enable it.

Answer 5

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.

Answer 6

ASP.NET Core 2.2 or later: For a 64-bit (x64) self-contained deployment that uses the in-process hosting model, disable the app pool for 32-bit (x86) processes.

In the Actions sidebar of IIS Manager > Application Pools, select Set Application Pool Defaults or Advanced Settings. Locate Enable 32-Bit Applications and set the value to False.
