Quickstart: using text, document and conversation summarization
Important
Our preview region, Sweden Central, showcases our latest and continually evolving LLM fine tuning techniques based on GPT models. You are welcome to try them out with a Language resource in the Sweden Central region.
Conversation summarization is only available using:
- REST API
- Python
- C#
Use this quickstart to create a text summarization application with the client library for .NET. In the following example, you'll create a C# application that can summarize documents or text-based customer service conversations.
Tip
You can use Language Studio to try text summarization without needing to write code.
Prerequisites
- Azure subscription - Create one for free
- The Visual Studio IDE
- Once you have your Azure subscription, create a Language resource in the Azure portal to get your key and endpoint. After it deploys, select Go to resource.
- You'll need the key and endpoint from the resource you create to connect your application to the API. You paste your key and endpoint into the code later in the quickstart.
- You can use the free pricing tier (
Free F0) to try the service, and upgrade later to a paid tier for production.
- To use the Analyze feature, you'll need a Language resource with the standard (S) pricing tier.
Setting up
Create environment variables
Your application must be authenticated to send API requests. For production, use a secure way of storing and accessing your credentials. In this example, you will write your credentials to environment variables on the local machine running the application.
To set the environment variable for your Language resource key, open a console window, and follow the instructions for your operating system and development environment.
- To set the
LANGUAGE_KEYenvironment variable, replaceyour-keywith one of the keys for your resource. - To set the
LANGUAGE_ENDPOINTenvironment variable, replaceyour-endpointwith the endpoint for your resource.
Important
If you use an API key, store it securely somewhere else, such as in Azure Key Vault. Don't include the API key directly in your code, and never post it publicly.
For more information about AI services security, see Authenticate requests to Azure AI services.
setx LANGUAGE_KEY your-key
setx LANGUAGE_ENDPOINT your-endpoint
Note
If you only need to access the environment variables in the current running console, you can set the environment variable with set instead of setx.
After you add the environment variables, you may need to restart any running programs that will need to read the environment variables, including the console window. For example, if you are using Visual Studio as your editor, restart Visual Studio before running the example.
Create a new .NET Core application
Using the Visual Studio IDE, create a new .NET Core console app. This creates a "Hello World" project with a single C# source file: program.cs.
Install the client library by right-clicking on the solution in the Solution Explorer and selecting Manage NuGet Packages. In the package manager that opens select Browse and search for Azure.AI.TextAnalytics. Make sure Include prerelease is checked. Select version 5.3.0, and then Install. You can also use the Package Manager Console.
Code example
Copy the following code into your program.cs file. Then run the code.
Important
Go to the Azure portal. If the Language resource you created in the Prerequisites section deployed successfully, click the Go to Resource button under Next Steps. You can find your key and endpoint by navigating to your resource's Keys and Endpoint page, under Resource Management.
Important
Remember to remove the key from your code when you're done, and never post it publicly. For production, use a secure way of storing and accessing your credentials like Azure Key Vault. See the Azure AI services security article for more information.

Windows 365 was in the works before COVID-19 sent companies around the world on a scramble to secure solutions to support employees suddenly forced to work from home, but “what really put the firecracker behind it was the pandemic, it accelerated everything,” McKelvey said. She explained that customers were asking, “’How do we create an experience for people that makes them still feel connected to the company without the physical presence of being there?”
In this new world of Windows 365, remote workers flip the lid on their laptop, bootup the family workstation or clip a keyboard onto a tablet, launch a native app or modern web browser and login to their Windows 365 account. From there, their Cloud PC appears with their background, apps, settings and content just as they left it when they last were last there – in the office, at home or a coffee shop.
“And then, when you’re done, you’re done. You won’t have any issues around security because you’re not saving anything on your device,” McKelvey said, noting that all the data is stored in the cloud.
The ability to login to a Cloud PC from anywhere on any device is part of Microsoft’s larger strategy around tailoring products such as Microsoft Teams and Microsoft 365 for the post-pandemic hybrid workforce of the future, she added. It enables employees accustomed to working from home to continue working from home; it enables companies to hire interns from halfway around the world; it allows startups to scale without requiring IT expertise.
“I think this will be interesting for those organizations who, for whatever reason, have shied away from virtualization. This is giving them an opportunity to try it in a way that their regular, everyday endpoint admin could manage,” McKelvey said.
The simplicity of Windows 365 won over Dean Wells, the corporate chief information officer for the Government of Nunavut. His team previously attempted to deploy a traditional virtual desktop infrastructure and found it inefficient and unsustainable given the limitations of low-bandwidth satellite internet and the constant need for IT staff to manage the network and infrastructure.
We didn’t run it for very long,” he said. “It didn’t turn out the way we had hoped. So, we actually had terminated the project and rolled back out to just regular PCs.”
He re-evaluated this decision after the Government of Nunavut was hit by a ransomware attack in November 2019 that took down everything from the phone system to the government’s servers. Microsoft helped rebuild the system, moving the government to Teams, SharePoint, OneDrive and Microsoft 365. Manchester’s team recruited the Government of Nunavut to pilot Windows 365. Wells was intrigued, especially by the ability to manage the elastic workforce securely and seamlessly.
“The impact that I believe we are finding, and the impact that we’re going to find going forward, is being able to access specialists from outside the territory and organizations outside the territory to come in and help us with our projects, being able to get people on staff with us to help us deliver the day-to-day expertise that we need to run the government,” he said.
“Being able to improve healthcare, being able to improve education, economic development is going to improve the quality of life in the communities.”`,

At the intersection of all three, there’s magic—what we call XYZ-code as illustrated in Figure 1—a joint representation to create more powerful AI that can speak, hear, see, and understand humans better. We believe XYZ-code will enable us to fulfill our long-term vision: cross-domain transfer learning, spanning modalities and languages. The goal is to have pre-trained models that can jointly learn representations to support a broad range of downstream AI tasks, much in the way humans do today. Over the past five years, we have achieved human performance on benchmarks in conversational speech recognition, machine translation, conversational question answering, machine reading comprehension, and image captioning. These five breakthroughs provided us with strong signals toward our more ambitious aspiration to produce a leap in AI capabilities, achieving multi-sensory and multilingual learning that is closer in line with how humans learn and understand. I believe the joint XYZ-code is a foundational component of this aspiration, if grounded with external knowledge sources in the downstream AI tasks."

Open a command prompt window (for example: BASH).
Paste the command from the text editor into the command prompt window, then run the command.
Get the
operation-locationfrom the response header. The value will look similar to the following URL:
https://<your-language-resource-endpoint>/language/analyze-text/jobs/12345678-1234-1234-1234-12345678?api-version=2023-04-01
- To get the results of the request, use the following cURL command. Be sure to replace
<my-job-id>with the numerical ID value you received from the previousoperation-locationresponse header:
curl -X GET $LANGUAGE_ENDPOINT/language/analyze-text/jobs/<my-job-id>?api-version=2023-04-01 \
