Well, here we will discuss How To Create And Deploy Azure Functions Time Trigger From Visual Studio 2019. Before we start discussing How to deploy the Azure functions timer trigger from Visual Studio 2019, we will discuss How To Create Azure Functions Time Trigger From Visual Studio 2019.
Before starting the actual development, we should know the Prerequisites
Prerequisites
- We need an Azure Account or Azure Subscription. Don’t have an Azure Account till now? no worries, create an Azure Free Account now.
- If you don’t have Visual Studio 2019 installed in your machine, install Visual Studio 2019 now. Along with Visual Studio 2019, you need to install the Azure development workload.
- We need Updated Azure Function tools
- You need an Azure Storage Account. If you don’t have an Azure Storage Account till now, create an Azure Storage Account now.
How To Schedule Azure Functions
Well, now we are ready for the development activities with all the Prerequisites needed. Let’s start the creating the Azure Function Project.
Now from your local machine, Open the Visual Studio 2019 and click on the Create a New Project button. On the Create a new project window, select the Azure Functions template and then click on the Next button.
You need to provide the below details in the below window
- Project name: Provide the Azure Function Project name
- Location: You need to choose a location for your Azure Function Project.
- Solution: Choose to Create new solution
Then, click on the Create button.
Now, this step is very important, We will have to choose a trigger for our Azure Functions. The role of the trigger is to invoke the Azure Function.
Make sure to choose the Timer Trigger as the template and then provide the below details
Storage Account (AzureWebStorage): choose the Storage Emulator option here.
Schedule: You can keep the CORN expression 0*/5**** as it is, this means the timer trigger Azure Function will execute on each 5 minutes interval of time. If You will change it to 0*/3****, then the Azure Function will execute on each 3 minutes interval of time. Decide based on your business requirement. Check out more details on the CORN expression now.
Finally, click on the Create button to create the timer trigger Azure Function.
Now you can able to see below, The Timer trigger Azure Function project created successfully with out any issue
Below is the Timer trigger Azure Function Code

using Microsoft.Extensions.Logging;
namespace TimeTriggerAzureFunction
{
public static class Function1
{
[FunctionName("mytimertriggerfunction")]
public static void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, ILogger log)
{
log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
}
}
}

On the next pop up, click on the Yes button to update the Azure Function version
Now your Azure Function will get publish successfully. Next step is we will verify if it is actually published successfully or not and then We will test if the Azure timer function is working or not.
To check all these things, you need to navigate to the Azure Function App that you have published just now.
Log in to the Azure Portal and search for the App services and then click on the search result. You will find your Azure function App in the list of app services. Click on your Azure Function App. Then, As shown below, On the Azure Function App page, click on the Functions from the left navigation
On the Azure Function page, click on the Code + Test link from the left navigation and then to test the Azure Function, if it is working fine as expected, click on the Test/Run button.
The next step is click on the Run button from the below window
Now you can see below we got the expected response code i.e 202 Accepted.
Now to see if the function executed on every 5 minutes or not, Select the log as Information, You can able to see the function execution time on each 5 minutes
Create Blob Trigger Azure Function In Visual Studio
Well, Above we discussed, How To Create And Deploy Azure Functions Time Trigger From Visual Studio 2019. Now let’s discuss How to Create Blob Trigger Azure Function In Visual Studio.
Prerequisites will be the same as Timer trigger Azure Function as mention above. So let’s start with the creation of the Blob trigger Azure Function using Visual Studio 2019.
Well, now we can start the development activities with all the Prerequisites needed. Let’s start creation of the Azure Function Project.
Open the Visual Studio 2019 and On the Create a new project window, click on the Create a New Project button. You need to select the Azure Functions template and then click on the Next button.
Provide the Project name, and choose a location for your project where you want to store your project from the below window and then click on the Create button.
Select the trigger template as Blob trigger and Storage Account (AzureWebJobsStorage) as Storage Emulator and then the next is Provide a name for the connection string setting and then click on the Create button
Now if you will see below, the project created successfully with out any issue
The below is the code for the Azure Function code that got created
public static class Function1
{
[FunctionName("Function1")]
public static void Run([BlobTrigger("samples-workitems/{name}", Connection = "MyDemoConnection")]Stream myBlob, string name, ILogger log)
{
log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
}
}The next step is we should make sure that the connection string is there with the same name that we provide before step i.e “MyDemoConnection” with the key-value pair in the local.settings.json file. Open the local.settings.json file.
So the key here is “MyDemoConnection” and we need the value for this, to get this value we need to log in to the Azure Portal. Log in to the Azure Portal, then navigate to the storage account and then click on the “Access keys” under settings from the left navigation. As highlighted below, You need to copy the connection string.
Now open your local.settings.json file and do the below changes, where you need to add the key and value pair for your Connection String. The local.settings.json file should look like below now.
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet",
"MyDemoConnection": "DefaultEndpointsProtocol=https;AccountName=mynewstoragedemo;AccountKey=pNWgITmf33ROgS1ixyUAQ4fIQIhaqBUWQjwI79/PjLy9zRoqEsvOQ7fn1gu41sj+dQ9eCHA/sDew8/OhDMfI9w==;EndpointSuffix=core.windows.net"
}
}
Now your function to work, it needs someplace to write the information. So you can write the information into the “AzureWebJobsStorage”.
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=mynewstoragedemo;AccountKey=pNWgITmf33ROgS1ixyUAQ4fIQIhaqBUWQjwI79/PjLy9zRoqEsvOQ7fn1gu41sj+dQ9eCHA/sDew8/OhDMfI9w==;EndpointSuffix=core.windows.net",
"FUNCTIONS_WORKER_RUNTIME": "dotnet",
"MyDemoConnection": "DefaultEndpointsProtocol=https;AccountName=mynewstoragedemo;AccountKey=pNWgITmf33ROgS1ixyUAQ4fIQIhaqBUWQjwI79/PjLy9zRoqEsvOQ7fn1gu41sj+dQ9eCHA/sDew8/OhDMfI9w==;EndpointSuffix=core.windows.net"
}
}You can see like below
To upload a file, to the storage container, you can do that using the Azure Storage Explorer
Open the Azure Storage Explorer, click on the Connect to Azure Storage button from the left navigation as highlighted below. select the Use a connection string option and then click on the Next button.
You can paste the same connection string as above. Display name will populate automatically, once you will put the value of the connection string and then click on the Next button.
Now it will show you the connection Summary details with all the information like below. Now click on the Connect button
You can able to see all the connection details and storage account details, Expand the
Provide the container name as samples-workitems which we have mention above as the path value. Click on the Upload and upload a file in your container. Then again you can run the Azure Function App again.
I have already uploaded one file in the samples-workitems container. Now if you will run (F5) the application, you can able to see the expected OutPut
Deploy Blob Trigger Azure Function From Visual Studio 2019
Now To deploy the Blob Trigger Azure Function From Visual Studio 2019, You need to follow the below steps
