Description

When using serilog object destructuring in a LoggerMessage template, the source generator won't recognize the parameter.

Reproduction Steps

Add this log message to a partial class:

[LoggerMessage(2020, LogLevel.Trace, "Transporting {@Response}")]
partial void LogTransporting(object response);

Expected behavior

The source generator should generate the logging method.

Actual behavior

The source generator creates an error: [SYSLIB1014] Template '@Response' is not provided as argument to the logging method

Regression?

No response

Known Workarounds

None. Using @ before the parameter name (as you would to escape reserved words) does not help.

Configuration

.NET 6.0.300
