我只是想从Visual Studio 2013测试预构建的Microsoft UCMA 4.0 Quickstart示例应用程序。
如果按开始键，我会收到警告：
Warning 1 The primary reference "Microsoft.Rtc.Collaboration, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the assembly "System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" which was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0". RecorderSample
和一堆错误，例如：
Error 3 The type or namespace name 'AudioVideo' does not exist in the namespace 'Microsoft.Rtc.Collaboration' (are you missing an assembly reference?) C:\Program Files\Microsoft UCMA 4.0\SDK\Core\Sample Applications\QuickStarts\AudioVideoCall\Recorder\RecorderSample.cs 10 35 RecorderSample
我的电脑上有.net framework 4.5.1
答案 0 :(得分：0)
我通过转到项目，项目属性，应用程序，目标框架并更改为4.5.1
来解决
