当我尝试创建一个新项目时，出现以下错误.我已经升级到CTP2. 错误:

I get the error below when I try to create a new project. I've upgraded to CTP2. Error:

The expression """.Substring(0, 6)" cannot be evaluated. Index and length must refer to a location within the string. Paramter name: length C:\USERS\ME\AppData\Roaming\npm\node_modules\vs-mda-targets\Microsoft.MDA.targets

The expression """.Substring(0, 6)" cannot be evaluated. Index and length must refer to a location within the string. Paramter name: length C:\USERS\ME\AppData\Roaming\npm\node_modules\vs-mda-targets\Microsoft.MDA.targets

发生此错误并检查解决方案文件夹时，尚未创建任何项目.

When this error occurs and I check the solution folder, no project has been created.

推荐答案

在VS关闭的情况下，在命令窗口中运行 npm -g uninstall vs-mda和npm -g uninstall vs-mda-targets

With VS closed, in a command window, run npm -g uninstall vs-mda and npm -g uninstall vs-mda-targets

检查是否删除了下的vs-mda和vs-mda-targets文件夹 C:\Users\YOUR-USER-NAME\AppData\Roaming\npm\node_modules\ 如果没有，您可以手动删除这些文件夹.

Check to see if this removed the vs-mda and vs-mda-targets folders under C:\Users\YOUR-USER-NAME\AppData\Roaming\npm\node_modules\ If it didn't, you can delete those folders manually.

然后重新启动VS并创建一个MDHA项目.它应该可以成功工作.

Then relaunch VS and create an MDHA project. It should work successfully.

如果在创建项目时遇到错误，指出未找到MDA目标，则可以手动安装'vs-mda'&从Visual Studio的扩展名"文件夹下单击"vs-mda-targets"，即可使工作再次正常进行.

If you get an error on project creation saying that the MDA targets were not found, you can manually install 'vs-mda' & 'vs-mda-targets' from under Visual Studio's Extension folder to get things working again.

退出Visual Studio并在安装Visual Studio的驱动器上，导航到 %Program Files%\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\uxbwjkun.gjn*\packages 在这里，您将找到两个文件夹"vs-mda"和"vs-mda-targets"

Exit Visual Studio and on the drive where Visual Studio is installed, navigate to %Program Files%\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\uxbwjkun.gjn*\packages Here you will find two folders "vs-mda" and "vs-mda-targets"

• 请注意，uxbwjkun.gjn并不是确切的文件夹名称，而是查找包含packages文件夹的类似文件.

现在从这里运行npm -g install <full path to current folder>\vs-mda和npm -g install <full path to current folder>\vs-mda-targets

发出此命令时，有必要在％Program Files％中的VS安装下为其提供vs-mda和vs-mda-targets文件夹的显式路径.

When issuing this command it's necessary to give it the explicit path to the vs-mda and vs-mda-targets folders under the VS installation in %Program Files%.

重新启动并创建一个新的MDHA项目.

Relaunch and create a new MDHA project.
