Practitioner Level

Detecting the Language of Text Using the .NET SDK

1 hour

5 Learning Objectives

In this hands-on lab, we will use Visual Studio and C# to access a pre-created Azure Cognitive Service resource and have it perform language detection. All the code is already written — we simply need to configure the service endpoint and key and run the code to perform the analysis.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Log In to the Azure Portal

Start by logging in to the Azure Portal using the credentials provided when starting the lab.

Use RDP to Connect to the Visual Studio Virtual Machine

Use the Remote Desktop client to access the virtual machine using the provided credentials:

Open and Configure Visual Studio

Open Visual Studio using either the Start menu or the desktop icon.
Use the credentials used to log in to the Azure Portal, not those used for the RDP authorization.
Select the defaults for all other Visual Studio options. Be patient as this takes a few minutes to complete.

Open the Visual Studio Solution

Open the solution in the c:code directory.

Configure the Endpoint and Key, Then Run the App

Retrieve the endpoint and key for the Cognitive Service resource and place them in the code.
Run the solution and examine the results.

Additional Resources

In this hands-on lab, we use a C# application on a Visual Studio virtual machine to detect the language of several pieces of text.

The application reports a confidence level for two strings: one in English and the other in French. The app can be used to try additional languages if desired.

The solution video demonstrates all the tasks in the objective list to complete the lab. Instructions are provided in each objective as well as the lab guide.

To begin, log in to the Azure Portal using the provided credentials.

Note: The latest stable release of Microsoft.Azure.CognitiveServices.Language.TextAnalytics requires "countryHint" as a parameter in the constructor of LanguageInput.
