Customers are encouraged to use the latest stable version as that is the version that will get fixes and updates. Beta packages are not recommended for use in production & support is limited. Upon release of the new stable version, the old Beta packages will be unlisted & the old minor version will be marked as deprecated. Application Insights follows the Azure SDK Lifecycle & support policy. (For example: When 2.20.0 is released, 2.20.0-beta1 will be unlisted and 2.19.0 will be deprecated.)

Nightly Builds are available on our MyGet feed: https://www.myget.org/F/applicationinsights-dotnet-nightly/api/v3/index.json

These builds come from the main branch. These are not signed and are not intended for production workloads.

A guide on common troubleshooting topics is available here.

For immediate support relating to the Application Insights .NET SDK we encourage you to file an Azure Support Request with Microsoft Azure instead of filing a GitHub Issue in this repository. You can do so by going online to the Azure portal and submitting a support request. Access to subscription management and billing support is included with your Microsoft Azure subscription, and technical support is provided through one of the Azure Support Plans. For step-by-step guidance for the Azure portal, see How to create an Azure support request. Alternatively, you can create and manage your support tickets programmatically using the Azure Support ticket REST API.
