TypeScript configurations in Visual Studio Code

Before sometime I have blogged about - Why It's the right time to learn Typescript and It does get lot of buzz. Typescript getting every day more popular due to reason I have mentioned in above blog post.  So now in this blog we are going to learn how we can use TypeScript with new Visual Studio Code editor.

TypeScript support in Visual Studio Code:

The Same scenario can occur for update or delete operations. If transactions are not there you will end up with lots of junk data in tables. Entity framework is one of most popular ORM in Microsoft.NET World. So in this post, we are going to learn how we can use transactions with Entity Framework 6.

But when you want to wrap multiple SaveChanges() method under single transaction there was not inbuilt functionality…

How to use stored procedure with Entity Framework Code First

I'm getting lots of request from readers of my blog about writing blog post about how to use stored procedure with entity framework code first. So in this blog post we're going to learn about how we can use stored procedure with Entity framework code first.

To demonstrate that we are going to use create a table called Employee like following.


And here is the create table script for the same.
CREATE TABLE [dbo].[Employee]( [EmployeeId] [int] NOT NULL, [FirstName] [nvarchar](50) NULL, [LastName] [nvarchar](50) NULL, [Designation] [nvarchar](50) NULL, CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED ( [EmployeeId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
And following is the data I have inserted there.



And here is the store procedure we are using for that.
CREATE PROCEDURE usp_GetAllEmployees AS SELECT EmployeeId,FirstName,LastName,Designation FROM Employee
Now we have…
