C# - DBus Secrets Test App

A test app for the DBus Secret Service API using Tmds.Dbus for cross-checking against Tmds.Dbus.SourceGenerator.

Secrets.DBus.cs is generated using Tmds.Dbus.Tool (with minor modifications + a namespace change):

dotnet dbus codegen --bus session --service org.freedesktop.secrets

Comparing Outputs

On my system, the expected output should be something like this (modification timestamps will be different):

Locked? False
Label: kdewallet
Created: 1676796746
Modified: 1694360288
Total Items: 4

Regular Tmds seems to be working when retrieving individual properties, but is broken when retrieving all properties at once (results in uninitialized values):

$ dotnet run --project SecretsTest.Standard/
Connecting to secret service...
Opened session at /org/freedesktop/secrets/session/44
Retrieving default collection...
Retrieved default collection

Retrieving individual properties...
Locked? False
Label: kdewallet
Created: 1676796746
Modified: 1694366682
Total Items: 4

Retrieving all properties...
Locked? False
Label: 
Created: 0
Modified: 0

Closing session...
Closed session

The source generator appears to be broken when retrieving individual properties, but works when retrieving all properties at once. The label can't be retrieved individually as it results in an IndexOutOfRangeException, while the total items can't be retrieved as it results in an ArgumentOutOfRangeException:

$ dotnet run --project SecretsTest.Generated/
Connecting to secret service...
Opened session at /org/freedesktop/secrets/session/45
Retrieving default collection...
Retrieved default collection

Retrieving individual properties...
Locked? True
Created: 29697
Modified: 29697

Retrieving all properties...
Locked? False
Label: kdewallet
Created: 1676796746
Modified: 1694366682
Total Items: 4

The IndexOutOfRangeException has the following stack trace:
