以编程方式构建.net3.5项目导致错误MSB4067：元素<project>下的元素<importgroup>无法识别

Question

我已编写代码来编程.net3.5项目编程，

var engine = new Engine
            {
                DefaultToolsVersion = "3.5",
                BinPath =  @"C:\Windows\Microsoft.NET\Framework64\v3.5"
            };

            var logger = new FileLogger { Parameters = @"logfile=" + MsBuildLogPath};

            engine.RegisterLogger(logger);

            var properties = new BuildPropertyGroup();
            properties.SetProperty("Configuration", "release");
            properties.SetProperty("OutputPath", @"bin\Release\");
            properties.SetProperty("Platform", "Any CPU");
            properties.SetProperty("TargetFrameworkVersion", "3.5");
            properties.SetProperty("OutputPath", destinationPath + @"\Output");

            bool result = engine.BuildProjectFile(solutionPath, new[] { "rebuild" }, properties);

我的msbuild路径是＆＃34; C：\ Windows \ Microsoft.NET \ Framework64 \ v3.5＆＃34;由于我的构建器项目基于.net3.5，并且出于某些原因我无法将其更新为.net4 。

编译项目导致错误

 "error MSB4067: The element <ImportGroup> beneath element <Project> is unrecognized"

我知道将我的项目更新为.net4并使用构建引擎4.0解决了我的问题，但正如我之前所说的由于某种原因我无法将我的项目更新为.net4并将构建路径切换到.net4 / msbuild。那么我该怎么做才能解决这个错误呢？

这是我的项目文件内容，不包含ImportGroup标记！
