Mongo DB Conditional Serialization

Mongo DB - Conditional Serialization

Sometimes, the documents retrieved from the database should be serialized differently for different conditions. We can make use of the below technique to do that,

public class Company {

public ObjectId Id { get; set; }

[BsonDateTimeOptions(DateOnly = true)]

public DateTime JoiningDate { get; set; }

public bool ShouldSerializeJoiningDate() {

return JoiningDate > new DateTime(1900, 1, 1);

}

For more information on conditional serialization, refer the Mongo DB documentation below

How to clear Visual Studio Cache

How to clear visual studio cache Many times, during development you would face situations where project references are not loaded properly or you get missing/error DLL's. This is because the Component cache gets corrupted randomly and without any warnings. The first option that needs to be done is to clear component cache and restart Visual Studio since the Cache might be holding onto previous DLL versions. Here are the steps on how to clear Visual Studio Cache, Clearing Component Cache: Close all Visual Studio Instances running in your machine.

Clearing User's Temp Folder: Open the temp folder in this locatio n - %USERPROFILE%\AppData\Loc

How to dependency inject to static class

.Net core supports dependency injection. There are many ways that you can inject services like constructor injection, action method injection, property injection. But there will be scenarios where you need to inject dependency services to static classes. For example, injecting services to extension methods. First, create a static class with a one property IServiceProvider type public void ConfigureServices(IServiceCollection services) { services.AddScoped<ILoggerEntry, LoggerEntry>(); services.AddTransient<IMongoRepository, MongoRepository>(); } Second, configure your services in ConfigureServices() method in Startup.cs and define the lifetime of the service instance using either Transient, Scoped or Singleton types. public void ConfigureServices(IServiceCollection services) { services.AddScoped<ILoggerEntry, LoggerEntry>(); services.AddTransient<IMongoRepository, MongoRepository>(); } For the next step to configure the Static class provider proper

PCF Health Check Delay - Invocation timeout

In PCF we can set up the health check invocation timeout to execute X seconds after the instance has been created. But before that, let's understand the PCF Health Check Lifecycle. Stage 1: The application is deployed to PCF Stage 2: When deploying the app, a health check type is specified and optionally a timeout. If a health check type is not specified, then the monitoring process defaults to a port health check Stage 3: Cloud Controller stages, starts, and runs the application Stage 4: Based on the type specified for the app, Cloud Controller configures a health check that runs periodically for each app instance Stage 5: When Diego starts an app instance, the app health check runs every two seconds until a response indicates that the app instance is healthy or until the health check timeout elapses. The 2-seconds health check interval is not configurable Stage 6: When an app instance becomes healthy, its route is advertised, if applicable. Subsequent hea
