Resolving Unauthorized Access Errors during .NET MAUI App Publication
Description
When publishing a .NET MAUI app for the first time, you might encounter errors indicating a failure to retrieve information about various System.ServiceModel.* packages from a remote source with a 401 (Unauthorized) response status code.
This issue arises because the NuGet package manager searches for Microsoft NuGet packages in the Telerik NuGet repository instead of the official NuGet repository.

Cause
The cause of the error is the misconfiguration of the NuGet package sources within the project. The project is incorrectly attempting to retrieve Microsoft NuGet packages from the Telerik NuGet server, where they are not available, leading to unauthorized access errors.
Solution
To resolve the unauthorized access errors, follow these steps:
- Open the
.csprojfile of your project. - Locate the package references that were being incorrectly searched for in the Telerik server. These references are likely to be
System.ServiceModel.*packages. - If any of these packages have a version specified with a "" (e.g., `1.0.`), replace the "*" with the exact version number you wish to use. Using specific versions helps ensure that the correct packages are located and used.
- Execute the following command in your terminal or command prompt to restore the packages from the official NuGet repository:
dotnet restore --source https://api.nuget.org/v3/index.json
This command forces the dotnet restore operation to use the official NuGet package source, ensuring that the correct packages are retrieved and unauthorized access errors are avoided.
