ServiceStack 和 AWS：創建了一個 ASP.NET 空項目，但無法在目標框架中選擇 .NET Core

[英]ServiceStack and AWS: Created a ASP.NET Empty project, but cannot select .NET Core in target framework

 原文  2019-08-15 12:57:52  5   2    c#/ visual-studio/ .net-core/ servicestack

問題描述

我在 VS2019 中啟動了一個 ServiceStack ASP.NET Empty 項目，因為這是我能找到的最接近我想要的東西。 模板是正確的，但我想在 .NET Core 中運行它。

但是，Target 框架設置為 .NET Framework 4.5，但我希望它是 .NET Core 2.1+，我也無法選擇它：

在此處輸入圖片說明

我知道我已經安裝了 .NET Core，因為我也在 VS2019 中開發了一個 Blazor 應用程序，它是 .NET Core。

我想知道我在這里缺少什么。

2 個解決方案

解決方案1

ServiceStackVS VS.NET Extension僅允許您創建 .NET Framework 項目。

要創建 ASP.NET Core 項目，您需要使用web new ，例如創建一個空的 ASP.NET Core 項目運行：

$ web new web ProjectName

解決方案2

嘗試打開您的.csproj進行編輯並將netcoreapp2.1作為您的目標框架。

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>
</Project>

通過從 cmd 運行dotnet --version來檢查全局安裝了哪個版本的 .NET Core。
