Azure Devops nuget 恢复无法解决依赖关系

Question

我有一个带有 EF 的 dotnet web api 项目。 当我尝试配置构建并运行Nuget 还原步骤失败并出现以下错误

The nuget command failed with exit code(1) and error(Errors in E:\TFS_Agents2017\...\s\ABC.Employees\ABC.Employees.csproj
    Unable to resolve 'Microsoft.NETCore.App (>= 3.1.0)' for '.NETCoreApp,Version=v3.1'.

Packages failed to restore

我错过了什么，我需要添加任何其他步骤吗？

我们在代理信息中看不到 .NET Core SDK 版本 3.1.0。 Please run the cmd dotnet –info to check your local .NET Core SDK version and Runtime version, then open the build definition and add the task .NET Core SDK and .NET Core restore to restore the package.
