MVC disable cache for controller action in debug mode

Question

I have controller action decorated with OutputCache attribute:

    [OutputCache(Duration = 60 * 60 * 12, VaryByParam = "*")]
    public ActionResult GetProducts(int id, string template, string version)

I would like to disable it in debug mode so I have used web.config transformation so in DEBUG mode I get this extra lines:

<caching>
  <outputCache enableOutputCache="false" enableFragmentCache="false" />
</caching>

But cache still works - action result is cached, changing code inside view make no effect when rendered.

Any ideas?

Wrap your [OutputCache] attribute in #if !DEBUG statement — haim770

You can do:

#if (!DEBUG)
[OutputCache(Duration = 60 * 60 * 12, VaryByParam = "*")]
#endif

#if (C# Reference)

Its a bit dirty and decentralized approach, but if there's no other way I will give it a try.

You need to use CacheProfile:

[OutputCache(CacheProfile = "CacheProfile1")]
public ActionResult GetProducts(int id, string template, string version)

web.config:

<system.web>
  <caching>
    <outputCacheSettings>
      <outputCacheProfiles>
        <add name="CacheProfile1" duration="0" varyByParam="*" />
      </outputCacheProfiles>
    </outputCacheSettings>
  </caching>
</system.web>

Transformation at web.Release.config:

<system.web>  
  <caching>
    <outputCacheSettings>
      <outputCacheProfiles>
        <add name="CacheProfile1" duration="43200" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
      </outputCacheProfiles>
    </outputCacheSettings>
  </caching>
</system.web>

When publishing it a release mode it will produce this for web.config:

<add name="CacheProfile1" duration="43200" varyByParam="*" />
