[英]How do I target .NET Standard 2.0 in a freshly created .NET Core 2.0 web app?
I've just created a fresh project using dotnet new web
. 我刚刚使用
dotnet new web
创建了一个新项目。 My Google-foo may be failing me, but I didn't find anything relating to my answer (please link to another SO answer, or relevant documentation if I've missed something obvious). 我的Google-foo可能会让我失望,但我没有找到任何与我的答案相关的内容(请链接到另一个SO答案,或相关文档,如果我错过了一些明显的东西)。
If I want to ensure this new project is .NET Standard 2.0 compliant, what do I now do? 如果我想确保这个新项目符合.NET Standard 2.0,我现在该怎么办?
NET Standard is for class libraries. NET Standard适用于类库。 Applications must target netcoreapp* where * is a version number.
应用程序必须以netcoreapp *为目标,其中*是版本号。 The following shows the compatibility matrix: https://docs.microsoft.com/en-us/dotnet/standard/net-standard
以下显示了兼容性矩阵: https : //docs.microsoft.com/en-us/dotnet/standard/net-standard
For example, .NET Core 2 can consume .NET Standard version 2 and below. 例如,.NET Core 2可以使用.NET Standard 2及更低版本。
It is not inherently possible to run a
netstandard
project as an executable.将
netstandard
项目作为可执行文件运行本身并不是可能的。 Sincenetstandard
was designed to be used for libraries.由于
netstandard
旨在用于图书馆。
In order to develop your web application entirely in netstandard2.0
, you would have to create a separate project that targets either .NET Core or .NET Framework to execute your library that contains your web app (developed using .NET Standard) . 为了完全在
netstandard2.0
开发Web应用程序, 您必须创建一个单独的项目,该项目以.NET Core或.NET Framework为目标,以执行包含Web应用程序的库(使用.NET Standard开发) 。
1. Executable Project (ex: console app)
-- Target Framework: netcoreapp2.0 / net462
2. Web Application Project (library)
-- Target Framework: netstandard2.0
You can use the following steps to change the target framework of your project. 您可以使用以下步骤更改项目的目标框架。
Step 1. Target the desired framework 步骤1.定位所需的框架
Right-click on your project and select Edit *****.csproj
右键单击您的项目,然后选择
Edit *****.csproj
In the .csproj
file, you need to replace the target framework to the .NET Framework. 在
.csproj
文件中,您需要将目标框架替换为.NET Framework。
Example .csproj file: 示例.csproj文件:
<Project Sdk="Microsoft.NET.Sdk.Web"> //<-- note the .Web for the web template
<PropertyGroup>
<TargetFramework>netstandard2.0</TargetFramework>
</PropertyGroup>
</Project>
For a list of the Target Framework Moniker (TFM) (ie, net47
, netstandard2.0
, netcoreapp2.0
, etc.*) you can check this link out: https://docs.microsoft.com/en-us/dotnet/standard/frameworks 有关Target Framework Moniker(TFM)的列表(即
net47
, netstandard2.0
, netcoreapp2.0
等*),您可以查看以下链接: https : netcoreapp2.0
/标准/框架
Step 2. Run dotnet restore
步骤2.运行
dotnet restore
Go to your output window and run dotnet restore
. 转到输出窗口并运行
dotnet restore
。
Note: Sometimes Visual Studio may misbehave (depending on which update you have installed), so you may have to close and re-open your Visual Studio. 注意:有时Visual Studio可能会出现异常(取决于您安装的更新),因此您可能必须关闭并重新打开Visual Studio。 Otherwise, sometimes a clean/re-build may do the trick.
否则,有时干净/重建可能会成功。
You can pick one or the other, or even target both frameworks. 您可以选择其中一个,甚至可以定位两个框架。
<TargetFrameworks>netcoreapp2.0; net47</TargetFrameworks> //<-- note the plural form!
