Modernize CSharpConsoleApp.csproj to SDK-style format

Converted CSharpConsoleApp.csproj from the legacy .NET Framework project format to the modern SDK-style format. Updated the target framework to net10.0, removed redundant property groups and references, and simplified the ProjectReference element. This streamlines the project file and aligns it with current .NET best practices.
