Solution:

TO enable cors in .net core web API, cors policy need to be added in the services. Below code in blue color needs to be added in the Startup.cs file

public void ConfigureServices(IServiceCollection services)

        {

            

            services.AddDbContext<AppDbContext>(options =>

                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

   

            services.AddCors(options =>

            {

                options.AddPolicy("Open", builder => builder.AllowAnyOrigin().AllowAnyHeader().WithMethods("PUT","DELETE","GET"));

            });


            services.AddControllers(); 

        }


 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

        {

            if (env.IsDevelopment())

            {

                app.UseDeveloperExceptionPage();

            }


            app.UseHttpsRedirection();


            app.UseRouting();


            app.UseAuthorization();


            app.UseCors("Open");


            app.UseEndpoints(endpoints =>

            {

                endpoints.MapControllers();

            });

        }

Create a batch file to copy/move files from network folder

Create a batch file (.bat) and paste the below code:

 @echo off

set DAYS=7

robocopy \\192.168.0.30\sanjeebapp\data\in E:\sanjeebapp\data\in\ /mov /maxage:%DAYS%

exit /b


Note: Change the source folder and destination folder as needed. /mov deletes the file from the source location . /maxage ignores the file which is older than DAYS. In this example, the files older than 7 days are not copied. 

Remove /mov from the script if you do not want to delete files in the source folder.

Create Build/Release Pipeline for SSIS in Azure SQL server



Create a new pipeline in devops.
Select the source:
Select an empty template

Select Get Sources in the left panel:


Now add a new agent job to Build SSIS. Click the + icon.



Search for SSS job. (if it's not already installed, then first install it from the marketplace)
Add SSIS build and then add SSIS Deploy 
Once you add these two jobs, your screen should look like this:

Now Select Build SSIS:
in the Project Path field, select the directory where .sln file is located. 
Leave the rest of the fields as default.
Now Select Deploy SSIS job to configure deploying settings 

add source path = $(Build.ArtifactStagingDirectory) (i.e. output path value from Build SSIS job-Previous step).
select destination type = SSISDB.
Destination Server = realdatabaseserver01.database.windows.net
Destination Path = /SSISDB/masterdatahub
Authentication type = SQL Server Authentication (you can choose any other option as per your need)


Click on the Triggers tab and configure Continuous Integration. 


Now Save and Queue the Pipeline. 
Once released you will see the ssis package under masterdatahub folder



That's everything for Azure devops continuous integration/ continuous deployment process for releasing ssis project to azure sql server. Good luck!

How To create SSIS user in Azure SQL server

I've assumed you have already configured domain in azure and have created a domain user.

Create Application in app registration  

First of all Create an app registration [myssissqlserver01]


Set up Active directory Admin in sql server

Now Go to the sql server (not the database) and on settings menu, click Active directory Admin



Click Set Admin and add your domain account. (in case you don't have domain configured , Configure a new domain and create a domain user first)

Connect to the database using MS Sql server management studio

Once admin is set , Open MS Sql server management studio and connect to the database.



Since we have added user to active directory admin, the user will have access to master database. So we can choose default database to connect, 


Create a user in ssis and add to a suitable role

Create a new query window selecting SSISDB database

execute the below queries. Note that the user name should be identical to the Application name created in App registration section . [ myssissqlserver01]

create user [myssissqlserver01] from external provider;

exec sp_addrolemember [db_owner],[myssissqlserver01];
