InvalidOperationException: Could not find 'UserSecretsIdAttribute' on assembly

Question

After deploying ASP.NET Core app to azure and opening the site, I get the following error:

InvalidOperationException: Could not find \'UserSecretsIdAt

Answer 1

I want to add to this answer, for those in my situation.

I am writing a .NET Core console app, trying to use the secrets manager (not sure it's meant for console apps). The only way I was able to rid myself of the error was using the assembly level attribute on the assembly where I was using the secrets manager.

As I said, I am not sure if the secrets manager is meant for console apps. So maybe there is an issue with .xproj files vs. .csproj files.
