The message is quite straightforward:

No valid '.sln' file could be found. Please read the previous log messages to know more.

This is because “sonar.dotnet.visualstudio.solution.file” property must point an SLN file, not to a folder like what you specified.

What’s more, there are too many useless properties in your “sonar-project.properties” file:

No need to specify the following properties as you set it to their default values:
- sonar.host.url
- sonar.jdbc.username
- sonar.jdbc.password
You specified “sonar.jdbc.username” and “sonar.jdbc.password” twice…
