We update Visual Studio often to extend its functionality and to fix customer-reported issues. To make sure you have the most current, optimized release of Visual Studio, you'll want to update it. Here's how.
Update by using the Notifications hub
When there are updates, you will see a notification flag in Visual Studio.
Click or tap the notification flag to open the Notifications hub.
Click or tap "Visual Studio Update" is available, which opens the Extensions and Updates dialog box.
In the Extensions and Updates dialog box, click or tap the Update button.
Update by using the Visual Studio Installer
Open the installer. You might need to update the installer before continuing. If this is the case, you'll be prompted to do so.
Note
On a computer running Windows 10, you'll find the installer under the letter V as the Visual Studio Installer, or under the letter M as the Microsoft Visual Studio Installer.
On the Product page in the installer, look for the edition of Visual Studio that you have installed.
If an update is available, you'll see an Update button. (It might take a few seconds for the installer to determine whether an update is available.)
Click or tap the Update button to install the updates.
