What does this error message mean?

class Program
{
    static async Task MainAsync(string[] args)
    {
        Account.accountTest accountTest = new Account.accountTest();

        bool result = await accountTest.CreateAccountAsync();

推荐答案

说明你的应用目前没有合适的入口点.

It means that you don't have a suitable entry point for your application at the moment.

该代码几乎可以与 C# 7.1 一起使用，但您需要在项目文件中显式启用 C# 7.1:

That code will nearly work with C# 7.1, but you do need to explicitly enable C# 7.1 in your project file:

<LangVersion>7.1</LangVersion>

或更笼统地说:

<LangVersion>latest</LangVersion>

您还需要将 MainAsync 重命名为 Main.比如:

You also need to rename MainAsync to Main. So for example:

程序.cs:

using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        await Task.Delay(1000);
    }
}

ConsoleApp.csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <LangVersion>7.1</LangVersion>
  </PropertyGroup>
</Project>

...构建并运行良好.

... builds and runs fine.
