Azure and .json mimeType without web.config
This should work:
<system.webServer> <staticContent> <remove fileExtension=".json" /> <mimeMap fileExtension=".json" mimeType="application/json" /> </staticContent></system.webServer>This doesn't make any difference to your overall IIS configuration, it just conditionally removes the mimeMap from the configuration of this particular site (as governed by this web.config) before adding it again.
You can create a startup task that adds the mime type on IIS level. This way you won't need to include it in your web.config:
"%windir%\System32\inetsrv\appcmd.exe" set config /section:staticContent /+"[fileExtension='.json',mimeType='application/json']"exit /b 0
