Enforce NuGet warnings as errors; refactor field access

Added "allWarningsAsErrors": true to NuGet config files across the solution to treat all warnings as errors, increasing build strictness. Updated project cache hashes and assembly info files to reflect these changes. Refactored C# code to use explicit `this.` for field and property assignments, improving clarity. Note: some method signatures were incorrectly changed to use `this.` as a prefix, which is invalid C# syntax and must be corrected before compiling. Binary files updated due to build changes.
