I can help you. do you have a visual studio 2019 ?
can you initiate the Live shares ?
this is the controller class at my end.
WeatherForecastController.cs
[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
private static readonly string[] Summaries = new[]
{
"Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
};
private readonly ILogger<WeatherForecastController> logger;
public WeatherForecastController(ILogger<WeatherForecastController> logger)
{
this.logger = logger;
}
[HttpGet]
public IEnumerable<WeatherForecast> Get()
{
var rng = new Random();
return Enumerable.Range(1, 5).Select(index => new WeatherForecast
{
Date = DateTime.Now.AddDays(index),
TemperatureC = rng.Next(-20, 55),
Summary = Summaries[rng.Next(Summaries.Length)]
})
.ToArray();
}
}
and this is the razor view
@page "/fetchdata"
@using EMS.Shared
@inject HttpClient Http
<h1>Weather forecast</h1>
<p>This component demonstrates fetching data from the server.</p>
@if (forecasts == null)
{
<p><em>Loading...</em></p>
}
else
{
<table class="table">
<thead>
<tr>
<th>Date</th>
<th>Temp. (C)</th>
<th>Temp. (F)</th>
<th>Summary</th>
</tr>
</thead>
<tbody>
@foreach (var forecast in forecasts)
{
<tr>
<td>@forecast.Date.ToShortDateString()</td>
<td>@forecast.TemperatureC</td>
<td>@forecast.TemperatureF</td>
<td>@forecast.Summary</td>
</tr>
}
</tbody>
</table>
}
@code {
WeatherForecast[] forecasts;
protected override async Task OnInitializedAsync()
{
forecasts = await Http.GetJsonAsync<WeatherForecast[]>("WeatherForecast");
}
}
and if you still face the same issue then you may need to verify following things.
Do you have a proper new install of .Net Core 3.0 ?
Second thing is
You need to install blazor preview 9 template.
Command for installing preview 9.
dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview9.19424.4
