In this guide, we will delve into understanding why this error occurs and how to resolve it effectively.

Understanding the Problem

When you attempt to deploy a .NET Core 2.2 project in Azure Pipelines, you might run into the above error during the dotnet restore step. This issue can stem from several factors, such as a mismatch between the SDK versions used, changes in Azure DevOps hosted agents, or issues in the project configuration.

Key Points to Note:

Azure Pipelines agents have been updated to support .NET Core 3.x (3.1) SDK/Runtime alongside 2.1.

If your project does not lock down a specific SDK version, the newer version might be picked up, leading to potential breaking changes.

Steps to Resolve the Issue

1. Verify Your Pipeline Configuration

The first step to troubleshooting this issue is to ensure that your Azure Pipelines configuration is correctly set to use the .NET Core 2.2 SDK. Here’s a basic YAML template that has successfully worked for similar scenarios:

2. Test with a Simplified Project

To narrow down the issue, consider creating a simple .NET Core 2.2 project and set it up as a new DevOps pipeline.

Steps to Create a Simple Project:

Create a new .NET Core 2.2 project locally.

Push this project to your repository.

Create a new pipeline targeted at this project and see if the error persists.

3. Run dotnet restore Locally

To better understand what might be going wrong, clone your original project to your local machine and run the following command:

Use a nuget.config:
If your project relies on specific package sources, ensure your nuget.config file is configured correctly.

Check Compatibility:
Make sure packages used in the project are compatible with .NET Core 2.2. Incompatible packages can sometimes cause restoration failures.

Conclusion

By following these steps, you should be able to resolve the deployment failure related to .NET Core 2.2 in Azure Pipelines effectively. Remember to verify your configurations, conduct local testing, and simply troubleshoot to identify any areas causing problems. If you continue facing issues, consulting Azure Pipelines documentation can provide further insights into troubleshooting specific errors.



With the right configuration and troubleshooting techniques, you can ensure that your .NET Core applications deploy smoothly in Azure Pipelines. Happy coding!
