503 Service Unavailable when deploy ASP.NET CORE 2.2 Angular 7 app in ISS


Currently, I'm working on an ASP.NET CORE 2.2 based project.

So, I wanted to host in IIS, which is on Windows Server 2012 R2 system. So, I followed the following steps:
  1. Installed the latest version of .NET Core Runtime & Hosting Bundle for Windows. Which you can find in this.
  2. Created the application pool with .NET CLR Version: No Manged Code
  3. Then created the web application pointing to that application pool.

But it was not working, and it started giving me 503 Service Unavailable error. The most important thing is, it was not only for this the web application that I created, but it was also for all the application hosted in this server. When I investigated more I found the following error in Event Viewer:

Error logged in Event viewer




After looking around for some time, I came to know that the ASP.NET Core/.NET Core: Runtime & Hosting Bundle (latest versions) depends on Microsoft Visual C++ 2015 Redistributable.
Even while installing the ASP.NET Core: Runtime & Hosting Bundle installer doesn't tell you about this missing piece.

This took more than 1 day for me to figure out the root cause. So, I hope this will help you guys to check for these prerequisites.

Exit a T-SQL Cursor When Condition is met

Have you ever wanted to exit from a cursor when a condition is met? I wanted to do it. So this is how I did it. DECLARE @Field1 AS INT DECLARE @Field2 AS INT DECLARE CursorName CURSOR READ_ONLY FOR SELECT Field1, Field2 FROM TableName OPEN CursorName FETCH NEXT FROM CursorName INTO @Field1, @Field2 WHILE @@FETCH_STATUS = 0 BEGIN IF @Field1 = 1 BEGIN GOTO ENDCURSOR END FETCH NEXT FROM CursorName INTO @Field1, @Field2 END ENDCURSOR: CLOSE CursorName DEALLOCATE CursorName I have set my fonts to bold where you want to notice. So that's all I hope you will get something out of it and it is true that this is not a big deal. :)

Generic Repository with Entity Framework Core

Recently I worked on a project with ASP.NET Core which uses Entity Framework Core. With them, I used a generic repository pattern in the data layer. Repository interface was like below: using System; using System.Collections.Generic; using System.Linq.Expressions; using OnlineSurvey.Models; namespace OnlineSurvey.Data { public interface IRepository<T> where T : BaseEntity { T GetById(int id, params Expression<Func<T, object>>[] includExpressions); void Add(T entity); void Delete(T entity); void Delete(int id); IEnumerable<T> GetAll(params Expression<Func<T, object>>[] includExpressions); IEnumerable<T> Find(Expression<Func<T, bool>> where); int Count(); } } And the implementation was like below: using System; using System.Data.Entity; using System.Data.Entity.Infrastructure; using System.Collections.Generic; using Syste
