无法读取配置节“ serviceAutoStartProviders”，因为它缺少节声明

Question

I am working on Hangfire, I want to use "serviceAutoStartProviders" in web.config for auto start. But where should I define "serviceAutoStartProviders" in web.config?

I got an error message of:

The configuration section 'serviceAutoStartProviders' cannot be read because it is missing a section declaration

My code is as below in web.configration:

<system.web>
    <serviceAutoStartProviders>
        <add name="ApplicationPreload" type="WebApplication1.ApplicationPreload, WebApplication1" />
    </serviceAutoStartProviders>
</system.web>

Answer 1

This should be defined inside a system.applicationHost element. If you take a look at the docs , you can see this from the doc structure (and even the URL path used) though I admit it's not particularly clear. For example:

<system.applicationHost>
    <serviceAutoStartProviders>
        <add name="ApplicationPreload" type="...." />
    </serviceAutoStartProviders>
</system.applicationHost>
