Added #pragma directives to suppress CS0612 warnings in various
methods using obsolete members. Updated `CairoExtensions.cs`,
`GdkExtensions.cs`, `MainWindow.cs`, `ReportArea.cs`,
`ReportViewer.cs`, and `ParameterPrompt.cs`. Added
`GlobalSuppressions.cs` for project-level suppressions.
Removed unused variables in `MainWindow.cs`.

Modified CurrentDirectory() in GeneralUtils.cs to use
System.Reflection.Assembly.GetExecutingAssembly().Location
instead of CodeBase. This change ensures the method returns
a straightforward absolute path to the executing assembly,
avoiding potential issues with URI formats and non-local paths.

Updated StringEncryption class to use Aes instead of RijndaelManaged.
- Replaced private field `rm` with `aes`.
- Modified constructor to initialize `aes` using `Aes.Create()`.
- Updated `Encrypt` and `Decrypt` methods to use `aes`.
- Improved readability of padding calculation logic.

Refactored code for readability and maintainability. Replaced `RNGCryptoServiceProvider` with `RandomNumberGenerator.Fill` for generating random bytes. Switched from `PasswordDeriveBytes` to `Rfc2898DeriveBytes` for PBKDF2 with SHA-256. Updated from `RijndaelManaged` to `Aes` for AES encryption. Replaced `try-finally` blocks with `using` statements for resource disposal. Streamlined `Create` and `Retrieve` methods for better clarity and efficiency.

Refactor synchronous methods to asynchronous using `async` and `await` keywords for improved performance and responsiveness. Replace `WebRequest` and `WebResponse` with `HttpClient` for modern, asynchronous HTTP requests. Update `GetImageStream` in `StyleBackgroundImage.cs` to fetch images asynchronously. Convert methods in `MhtBuilder.cs`, `MhtWebClientLocal.cs`, and `MhtWebFile.cs` to async versions. Update `RunRenderMht` in `Report.cs` to call the async `SavePageArchive`. These changes enhance the application's performance and scalability.

Introduced HttpClientExtension class with AddMajorsilenceReportingUserAgent method to set a custom User-Agent header. Updated various methods to use this extension, ensuring consistent User-Agent headers across HTTP requests. Added necessary using directives for RdlEngine.Utility namespace.

Updated several methods in DesignXmlDraw.cs and DesignCtl.cs to be asynchronous, improving performance and responsiveness. The `HttpClientExtension` class is now public, and its `AddMajorsilenceReportingUserAgent` method is used to set the user agent header in `HttpClient`. The `DrawImageExternal` method now uses `HttpClient` instead of `WebRequest`.

Converted various methods in DesignCtl.cs and DesignXmlDraw.cs to use async/await for non-blocking operations. Updated SelectedStyle property in DesignCtl.cs to retrieve style info asynchronously. Modified multiple drawing methods in DesignXmlDraw.cs to be asynchronous. Changed GetStyleInfo and its helper method to handle HTTP requests using HttpClient for better performance.

Updated the `Directory.Build.props` file to increment the
`AssemblyVersion`, `FileVersion`, and `Version` properties
from `5.0.0` to `5.0.1` and `5.0.1-alpha`. This change
indicates a minor update or patch, with the `-alpha` suffix
denoting an alpha release of the new version.

…esign namespace

Changed constructors from internal to public in several classes
within the fyiReporting.RdlDesign namespace. This allows for
greater flexibility in creating instances of these classes from
other assemblies. Affected classes include PropertyAction,
PropertyAppearance, PropertyBackground, PropertyBorder,
PropertyExpr, PropertyTable, and PropertyVisibility, along with
their respective UIEditor classes.

if net8.0 runtime errors

Updated instantiation of ZXing.BarcodeWriter in AztecCode.cs, BarCode128.cs, BarCode39.cs, BarCodeEAN8.cs, and QrCode.cs to use different types based on compilation symbols. For DRAWINGCOMPAT, replaced with ZXing.SkiaSharp.BarcodeWriter. For NETSTANDARD2_0 or NET5_0_OR_GREATER, replaced with ZXing.Windows.Compatibility.BarcodeWriter. Default remains ZXing.BarcodeWriter. These changes ensure compatibility with different frameworks and improve barcode writing for various image formats.

Added a comprehensive .editorconfig file to enforce consistent coding standards for C# files. Included the .editorconfig file in a new "Solution Items" project within the MajorsilenceReporting.sln solution file.

Updated .editorconfig to include a new rule enforcing the CA2000 diagnostic, which ensures objects are disposed of before losing scope. The severity for this rule is set to "warning" to improve resource management and code quality.

Refactor: Convert synchronous methods to async

Converted several synchronous methods to asynchronous across multiple files to improve performance and responsiveness. Key changes include:
- Updated methods in `ChartBar.cs`, `ChartColumn.cs`, `ChartPie.cs`, and `CustomReportItem.cs` to use `await`.
- `GetCategoryValue` now returns a tuple instead of using an `out` parameter.
- Made `GetFilteredData` in `DataRegion.cs` asynchronous.
- Updated `ValuesCalc` in `DefaultValue.cs` and its callers to use `await`.
- Refactored `Apply` methods in `Filter.cs` and `Filters.cs` for async operations.
- `RunPage` in `Image.cs` now awaits `_Value`.
- Made methods in `List.cs` like `RunSetGrouping`, `PrepGroups`, and `RunPage` asynchronous.
- Refactored `MatrixEntry.cs` for readability and updated `Compare` in `MatrixEntryComparer` to use `Task.Run`.
- Updated methods in `Query.cs` to use `await` for async operations.
- `DefaultValue` in `ReportParameter.cs` now uses `Task.Run` for `ValuesCalc`.
- Updated `Compare` in `RowsSortExpression` to use `Task.Run`.
- `GetPageImage` in `StyleBackgroundImage.cs` now awaits `_Value`.
- Made methods in `Subreport.cs` and `Table.cs` asynchronous.
- Updated `Evaluate` methods in various classes to be asynchronous.

These changes enhance the application's performance and scalability by leveraging asynchronous programming.

Refactored the Query class and methods for improved readability and maintainability. Added `using` statements for proper disposal of `IDbCommand` and `IDataReader` resources. Introduced a helper method `CreateDataReader` to streamline data reader creation. Modified `GetData` to apply filter logic within the loop. Reformatted various methods and properties for consistent formatting.

Updated .editorconfig to set CA2007 and CA4014 severities to warning and error respectively. Refactored path handling in RdlDesigner.cs, RdlDesktop.cs, and RdlReader.cs to use new methods from the newly added RdlEngine.Utility.Paths class. Made menuEditFind_Click asynchronous in RdlDesigner.cs. Improved exception rethrowing in FileReadCache.cs and EMFRecordObject.cs to preserve original stack traces.

…lems with async code in Paint method

- Enabled double buffering in the `DesignCtl` constructor.
-HACK: Refactored `DrawPanelPaint` to handle drawing asynchronously with a `Bitmap` buffer and an `async` method `Internal_DrawPanelPaint`.
- Added a `Dispose` method to clean up the `Bitmap` buffer.
