Using Cache in .NET Core

 Register the service in startup.cs:

services.AddMemoryCache((opts) => 
{ 
});

Inject it as IMemoryCache (e.g. in a controller):

HomeController(IMemoryCache memoryCache) {
    this.memoryCache = memoryCache;
}

Set a new value:

cache.Set("accessToken", 
	response.Data.AccessToken, 
	TimeSpan.FromSeconds(response.Data.ExpiresIn - 60)
);

Get value:

cache.TryGetValue("accessToken", out string accessToken);
