如何仅在 ASP.NET Core 中禁用缓存以进行开发？

Question

I want to disable caching when running ASP.NET core application in Development environment. How can i do that?

I'm setting cache up in Startup:

services.AddMemoryCache();

I want to disable cache in templates, which use the <cache> tag:

<cache expires-after="@TimeSpan.FromSeconds(3600)">

You can simply inject IHostingEnvironment into the startup constructor of your Startup.cs

Like So

      private readonly IHostingEnvironment _environment;

       public Startup(IConfiguration configuration,IHostingEnvironment environment)
       {
        _environment = environment;
        Configuration = configuration;
       }

Then you can use the private IHostingEnvironment inside your configures services method .

public void ConfigureServices(IServiceCollection services) 
{
 if(!_environment.IsDevelopment())
    services.AddMemoryCache();
}

EDIT :

After rereading the question the cache tags should be disabled aswell. I would suggest adding a flag inside your appsettings.devlopment.json called "PageCachingEnabled": "false" .

On the view I would then inject the configuration like so

@using Microsoft.Extensions.Configuration
@inject IConfiguration Configuration
<cache enabled=@Boolean.Parse(Configuration["PageCachingEnabled"]) expires-after="@TimeSpan.FromSeconds(3600)">

The trick is to use services.AddDistributedMemoryCache(); in development, this will use the memory of the running system as a cache.

if(Env.IsDevelopment()) {
  services.AddDistributedMemoryCache();
} else {
  services.AddStackExchangeRedisCache();
}
