是的，Azure DevOps管道可以构建
net5.0应用。如果您正在使用“.Net Core”（yaml中为
DotNetCoreCLI）任务进行构建-请在其前面添加“Use .NET Core”（yaml中为UseDotNet）任务，并使用正确的版本：sqxo8psd2#
支持此功能。
由于您使用的是.Net 5，请尝试使用带有restore命令的
Use .net core task和Dotnet core task，而不要使用Nuget restore。强烈建议针对以
.net core为目的的项目使用dotnet restore和dotnet build责任。请参阅this statement from Nuget task：再看一下这个类似的问题：Azure CI pipeline for Blazor .NET 5 doesn't work

希望这个答案能帮助那些仍然在Azure DevOps中使用“经典管道”（而不是yaml）的人。
有完全相同的任务模板来设置.net core sdk的特定版本，可以通过搜索对话框添加：
将其包含在您的管道中并通过UI设置正确的版本。还要确保它在实际的构建/发布步骤之前运行。

我需要使用两个framework版本来构建我在. net5中的函数。
