Net Core 2.1项目TFS构建报错：GetTargetFrameworkIdentifier调用语法无效

错误详情 #

C:\Program Files\dotnet\sdk\6.0.102\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(54,5): error MSB4186: Invalid static method invocation syntax: "[MSBuild]::GetTargetFrameworkIdentifier('$(TargetFramework)')". [MSBuild]::GetTargetFrameworkIdentifier Static method invocation should be of the form: $([FullTypeName]::Method()), e.g. $([System.IO.Path]::Combine(`a`, `b`)).

    });

错误原因 #

• SDK与MSBuild版本不兼容：构建过程调用了.NET 6.0 SDK（路径显示为6.0.102），该SDK目标文件中使用的[MSBuild]::GetTargetFrameworkIdentifier语法，在适配.NET Core 2.1的旧版MSBuild（如VS2017配套的MSBuild 15.x）中不被支持，语法格式不符合旧版要求。
• 版本匹配缺失：.NET Core 2.1项目需要对应版本的SDK（2.1.x）和MSBuild版本构建，系统中存在更高版本SDK时，若未明确指定版本，MSBuild会优先调用最新SDK，触发语法不兼容报错。
• Cake脚本逻辑问题：当useLatestMsBuild为true时，未限制SDK版本，直接调用最新MSBuild必然引发版本冲突；即使指定了VS2017的MSBuild版本，若环境变量或全局SDK指向未调整，仍可能拉取高版本SDK执行构建。
