I'm currently using Visual Studio Professional 2022 17.8.9. If I create a WPF project, I'm able to browse Nuget packages. However, if I create a MAUI project and try to browse Nuget, I get the following error message
-
[nuget.org] Unable to load the service index for source https://api.nuget.org/v3/index.json.
An error occurred while sending the request.
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
The remote certificate is invalid according to the validation procedure.

Why is this an issue for MAUI projects but not WPF projects?
Deleting the nuget.config file did not help. This is also a fresh install of VS.
I also see this error:
Error [nuget.org] Unable to load the service index for source https://api.nuget.org/v3/index.json.
An error occurred while sending the request.
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

For this issue, you could try to delete the
%AppData%\NuGet\nuget.configand restart your Visual Studio to install the nuget packages. -
