没有找到匹配约束的导出：ContractName [英] no exports were found that match the constraint:ContractName

问题描述

我使用的是MS Visual Studio Professional 2012，版本：11.0.51106.01。从过去几天意识到，我不能再创建一个新的项目与模板JavaScript。我能够做到这一点。我猜这可能是由于一些系统更新发生。

I am using MS Visual Studio Professional 2012, Version: 11.0.51106.01. Since past few days realized that i am no more able to create a new project with template JavaScript. I was able to do this before. I am guessing this might have happened due to some system update.

这是我尝试创建一个新项目时的错误日志：

Here is the error log when i try to create a new project:

找不到符合约束的导出：ContractName
Microsoft.VisualStudio.Text.ITextDocumentFactoryService
RequiredTypeIdentity
Microsoft.VisualStudio.Text.ITextDocumentFactoryService

no exports were found that match the constraint:ContractName Microsoft.VisualStudio.Text.ITextDocumentFactoryService RequiredTypeIdentity Microsoft.VisualStudio.Text.ITextDocumentFactoryService

请帮助我最早解决这个问题，因为我还没有找到很多在线。

Please help me resolve this issue at the earliest as i have not been able to find much online.
