I have a pre-existing VB.NET web application running on IIS 8 in Windows Server 2012 R2. The application needs to handle a new API call (ex. localhost/test/ping) which I implemented using the APIController interface. I was able to successfully run the API call on my local Visual Studio, but once I deploy it to IIS, the url returns a 404 error.
After some digging and research, part of the problem I believe is the web app does not have ExtensionlessUrlHandler-Integerated-4.0 in the handler mapping. Looking into the configurations, apparently part of the pre-condition is the application cannot be me in classic mode, which mine is. I cannot switch to integrated mode which will break my app.
Is there a way around this limitation.
Update: Adding the web.config
<system.webServer> <modules runAllManagedModulesForAllRequests="true" /> <handlers> <add name="MVC" path="*." verb="*" type="" modules="IsapiModule" scriptProcessor="C:WindowsMicrosoft.NETFrameworkv2.0.50727aspnet_isapi.dll" resourceType="File" requireAccess="None" allowPathInfo="false" preCondition="classicMode,runtimeVersionv2.0,bitness32" responseBufferLimit="4194304" /> </handlers> </system.webServer>
