问题描述
我是GitHub项目的贡献者,最近我们的 .NET标准遇到了一些麻烦2.0项目正确安装到.NET Framework 4.5项目中.原因是(如果我理解正确的话) .NET Standard 2.0支持的最低.NET Framework为4.6.1 .
I am a contributor to a GitHub project, and recently we had some trouble with our .NET Standard 2.0 project installing correctly into a .NET Framework 4.5 project. The cause of this is that (if I am understanding correctly) .NET Standard 2.0 supports a minimum .NET Framework of 4.6.1.
好的,很公平.因此,我们更新了.csproj来创建另一个框架输出:
OK, fair enough. So we updated the .csproj to create another framework output:
<TargetFrameworks>netstandard2.0;net45</TargetFrameworks>
在我们的测试项目中,受支持的框架的定义如下:
In our testing project, the supported frameworks are defined as such:
<TargetFrameworks>netcoreapp2.0;net471;net45</TargetFrameworks>
但是,我们遇到了net471
构建的问题,因为它似乎是在拾取net45
框架而不是netstandard2.0
.为了使此工作正常,我们必须将类库的TargetFrameworks
设置为:
However, we are running into a problem with the net471
build as it seems to be picking up the net45
framework and not the netstandard2.0
. In order to get this working, we are having to set the TargetFrameworks
of the class library as such:
<TargetFrameworks>netstandard2.0;net471;net45</TargetFrameworks>
这似乎太过分了,因为.netstandard2.0
应该是net471
拾取的TargetFramework
,而不是net45
目标.
This seems excessive as it would seem that .netstandard2.0
should be the TargetFramework
that net471
picks up, rather than the net45
target.
是否有一种方法可以强制将项目引用引用到特定的TargetFramework
?我在测试项目中确实尝试了以下方法,但是似乎没有用:
Is there a way to force a project reference to a particular TargetFramework
? I did try the following in our testing project, but it did not seem work:
<ItemGroup Condition="'$(TargetFramework)' != 'net471'">
<ProjectReference Include="..\..\src\ExtendedXmlSerializer\ExtendedXmlSerializer.csproj" />
</ItemGroup>
<ItemGroup Condition="'$(TargetFramework)' == 'net471'">
<ProjectReference Include="..\..\src\ExtendedXmlSerializer\ExtendedXmlSerializer.csproj">
<TargetFramework>netstandard2.0</TargetFramework>
</ProjectReference>
</ItemGroup>
在此先感谢您提供的任何帮助!
Thank you in advance for any assistance you can provide!
推荐答案
是的,解决这个问题的新方法是:
It is true, the new way to solve that is this:
<ProjectReference Include="..\multitargeted_lib\multitargeted_lib.csproj">
<SetTargetFramework>TargetFramework=netstandard2.0</SetTargetFramework>
</ProjectReference>
