installutil with custom cache key generator

[johnecon]

I am developing a web service using ASP.NET WEB API 2 and Owin and it is supposed to run as a windows service. Simple caching using CacheOutputUntilToday(23,55) works fine but I want to add the authorization header to the cache key, since it seems it is not included in the key. For this reason I created a class that implements ICacheKeyGenerator:

using System.Web.Http.Controllers;
using System.Net.Http.Headers;
using WebApi.OutputCache.V2;
class CustomCacheKeyGenerator : ICacheKeyGenerator
{
    public string MakeCacheKey(HttpActionContext context, MediaTypeHeaderValue mediaType, bool excludeQueryString = false)
    {
        return context.Request.Headers.Authorization.ToString() + context.Request.RequestUri.ToString();
    }
}

and I use it in the Startup.cs as shown:

HttpConfiguration config = new HttpConfiguration();
config.CacheOutputConfiguration().RegisterDefaultCacheKeyGeneratorProvider(() => new 
     CustomCacheKeyGenerator());

The command installutil myservice.exe gives back the following error:

leAppService\bin\Release\SalesRepMobileAppService.exe'.

There are so many different solutions for this out there but none worked for me until now. Any help would be highly appreciated

did you compile the service as .net 4.5?
