SharpSkylazer，您好

Hi SharpSkylazer,

此问题仅发生在当前项目或Visual Studio 2017 RC创建的所有项目中吗?我创建了一个WPF项目，该项目用于调用控制台应用程序，并且在我新安装的VS2017 RC中可以正常工作.

Is this issue only occurs in current project or all projects created by Visual Studio 2017 RC? I create a WPF project which used to invoke a console application and it works fine in my new installed VS2017 RC.

如果仅在此特定项目中发生，则此问题应与升级到VS2017时的项目本身有关.建议您创建一个新的WPF项目，然后将原始项目文件复制到该新项目中，然后再次尝试调试.

If just occurs in this specific project, this issue should be related to your project itself when upgrade to VS2017. I suggest you create a new WPF project and then copy the original project files into this new project and try debug again.

如果在VS2017 RC中调试所有项目时发生此问题，则恐怕VS2017 RC安装中存在一些问题.我建议您修复它以检查是否可以解决此问题.

If this issue occurs when debugging all projects in VS2017 RC, I'm afraid that there has some problem in your VS2017 RC installation. I suggest you repair it to check whether this issue could be fixed.

此外，VS2017 RC已发布更新.请打开VS2017 RC安装程序，它将提示您安装此更新.

In addition, VS2017 RC has an Update released. Please open the VS2017 RC installer, it will prompt you to install this update.

***的问候，
