Build my first Blazor app

     While reading C# 8.0 recently, I came across an article about writing wasm. Here is an example of how to build Blazor.

    command prompt :dotnet new blazorserver -o BlazorApp --no-https  and cd BlazorApp ,and dotnet run

 Counter.razor

@page "/counter"

<PageTitle>Counter</PageTitle>

<h1>Counter</h1>

<p role="status">Current count: @currentCount</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}

at index.rator:

@page "/"

<PageTitle>Counter</PageTitle>

<h1>Hello, world!</h1>

Welcome to your new app.

<SurveyPrompt Title="How is Blazor working for you?" />

<Counter />

to change:

@page "/counter"

<PageTitle>Counter</PageTitle>

<h1>Counter</h1>

<p>Current count: @currentCount</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private int currentCount = 0;

    [Parameter]
    public int IncrementAmount { get; set; } = 1;

    private void IncrementCount()
    {
        currentCount += IncrementAmount;
    }
}

　　

@page "/"

<h1>Hello, world!</h1>

Welcome to your new app.

<SurveyPrompt Title="How is Blazor working for you?" />

<Counter IncrementAmount="10" />
