MemoryCache | LRU , type-safe , thread-safe memory cache class in Swift | Caching library

I'm porting a legacy ASP.NET WebForms app to Razor. It had stored an object in the Session collection. Session storage is now limited to byte[] or string. One technique is to serialize objects and store as a string, but there are caveats. Another article suggested using one of the alternative caching options, so I'm trying to use MemoryCache.

For this to work as a Session replacement, I need a key name that's unique to the user and their session.

I thought I'd use Session.Id for this, like so:

I'm trying to create a PDF viewer composable using the PdfRenderer and Coil for loading the bitmaps into a LazyColumn. This is what I got so far:

I have api project in .net core. When I was restaring azure service for this api, IDistributedCache is cleared. After restarting, while fetching data from GetSubscriptionRecord() method it returns null.

My startup.cs contains

I want to clear the memory cache by a specific key generated by the tag helper. It is possible to clear the whole memory cache generated by the cache tag using the below code.

I'm using an ObjectCache object as MemoryCache.Default (System.Runtime.Caching) and my policy contains AbsoluteExpiration.

for example:

I have a Windows Server 2019 with an IIS server for .NET5 application with React frontend uses IMemoryCache to store data from DB. It loads over 5GB for 6 minutes into Memory (over 500 000 000 rows).

When I run app from VS Professional, Cache works perfectly for more than 6-12 hours (or more), but after I deploy & run the web app on IIS, Cache works less than 30 minutes

I have a .Net Core application with EF which returns a page called Customer as home page. But I need show an app not available page (AppNotAvialable.cshmtl) when the user tries to access the application on a holiday(holiday list is stored in a table)instead of the Customer page. Instead of querying the holiday list table every time the home page is accessed I am trying to use the In-Memory Cache so I can store the query response in cache and use them in the controller. I am implementing the cache for the 1st time and below is what I tried

I am trying to build a .NET core application that uses EF core and alos using Caching to store some of the query response. I am having issue with accessing fields from the LINQ query response. I am not sure what is that I am missing here. There is a Setting table in the SQL Server DB and the model is like below

I stumbled upon this error while running my application.

System.AggregateException: 'Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Microsoft.Extensions.Hosting.IHostedService Lifetime: Singleton ImplementationType: testing.CacheUpdater': Unable to resolve service for type 'testing.CacheMonitorOptions' while attempting to activate 'testing.CacheUpdater'.

App explanation I am making an application where I periodically(every 10secs) update the MemoryCache with values I fetch from my database.

For this I am using 3 classes, CacheMonitor (which is responsible for the update/override of cache), StudentsContext (which is responsible for fetching the data from the database) and CacheUpdater which is a background service that calls the Update method within the CacheMonitor class.

I have injected them into my DI container like this:
