Updated target frameworks to .NET 10.0 in `BlazorBootstrap.Demo.RCL.csproj`and `BlazorBootstrap.Demo.WebAssembly.csproj`. Upgraded package referencesto version `10.0.0` of relevant libraries.Enabled HTML asset placeholders in `BlazorBootstrap.Demo.WebAssembly.csproj`.Improved `App.razor` formatting and added preloading and import map supportin `index.html`. Introduced cache-busting placeholders for JavaScript files.Removed unused `<Folder>` entry in `BlazorBootstrap.Demo.RCL.csproj` toclean up the project structure.

Upgraded the target framework to .NET 10 in `BlazorBootstrap.Demo.Server.csproj` and added the `BlazorDisableThrowNavigationException` property.Enhanced `App.razor` with `<ResourcePreloader />`, `<ImportMap />`, and a new `<ReconnectModal />` component for handling reconnection scenarios. Updated script references to use dynamic asset management.Added a `ReconnectModal.razor` component with a `<dialog>` element, user interaction buttons, and messages for reconnecting, retrying, and resuming sessions. Styled the modal with animations in `ReconnectModal.razor.css` and implemented reconnect logic in `ReconnectModal.razor.js`.Modified `_Imports.razor` to include layout components. Updated `Program.cs` to use `app.MapStaticAssets()` and `app.MapRazorComponents` for interactive server rendering and added custom status code handling.These changes improve user experience, modularity, and resilience to connectivity issues.

Updated `<link>` and `<script>` tags in `App.razor` to use the`@Assets` syntax for referencing asset paths dynamically.This change was applied to multiple CSS and JavaScript files,including `blazor.bootstrap.css`, `blazorbootstrap.demo.rcl.css`,`BlazorBootstrap.Demo.Server.styles.css`, and their correspondingJavaScript files.This refactor improves maintainability by centralizing assetpath management and ensures consistency in asset referencingthroughout the application.

This commit removes the Blazor Hosted Server and WebAssembly applications, along with their associated files, assets, and configurations:- Deleted `BlazorBootstrap.Demo.Hosted.Server` and `BlazorBootstrap.Demo.Hosted.Client` projects.- Removed routing logic, startup code, and launch settings.- Deleted application settings (`appsettings.json`, `appsettings.Development.json`).- Removed Razor pages (`_Host.cshtml`, `Error.cshtml`) and controllers.- Deleted image assets (`placeholder.png`, multiple icons, and logos).- Removed `sitemap.xml` and other project-specific files.- Updated `blazorbootstrap.sln` to reflect project removals.These changes indicate the decommissioning or migration of the Blazor Hosted and WebAssembly applications.

The `dotNetVersion` value in the `appsettings.json` file was updated from `"9.0.0"` to `"10.0.0"`. This change reflects the application's compatibility with .NET version 10.0.0, ensuring it targets the latest framework version.
