How can you read the current value of an input element in Blazor?
The value of an input element is updated in the wrapper with the change events of elements in Blazor. To get the current value for each character input, you must use the oninput event of the input element. This can be achieved by binding the oninput event (native event) using the @bind:event=“oninput“.
How do I pass arguments to the onclick event in Blazor?

While upgrading Blazor applications, you many encounter these issues. You have to do the following changes to properly run the application: Update all Microsoft.AspNetCore.Blazor.* package references to 3.0.0-preview4-19216-03. Remove any package reference to Microsoft.AspNetCore.Components.Server. Remove any DotNetCliToolReference to Microsoft.AspNetCore.Blazor.Cli and replace with a package reference to Microsoft.AspNetCore.Blazor.DevServer. In client Blazor projects, remove the <RunCommand>dotnet</RunCommand> and <RunArguments>blazor serve</RunArguments> properties. In client Blazor projects, add the <RazorLangVersion>3.0</RazorLangVersion> property. Rename all _ViewImports.cshtml files to _Imports.razor. Rename all remaining .cshtml files to .razor. Rename components.webassembly.js to blazor.webassembly.js Remove any use of the Microsoft.AspNetCore.Components.Services namespace and replace with Microsoft.AspNetCore.Components as required. Update server projects to use endpoint routing. Run dotnet clean on the solution to clear out old Razor declarations.
