You've installed analyzers through NuGet.  Remove and reinstall the analyers.

 I have not install analyzers at all.
I have just install This Package through NuGet.

I had the same issue.  Removing and reinstall the analysers worked for me. Or just remove the analyzers as the error is related JavaScript validation.

It also seems that you have NuGet  reference issues where you might need to update/downgrade the packages.  Sometimes just restarting VS removes the error or running "dotnet restore" from the PMC.

How to Solve This Problem ?

According to your description, I found this error is thrown by ESLint.

As far as I know, the VS team has reimplemented ESLint support for15.8

If you don't want to use it, you could disable it.

More details, you could refer to below answer:

https://stackoverflow.com/a/44458832/7609093 

From release article.

We reimplemented ESLint support for this release. ESLint has the following improvements and enhancements:

• Rather than only linting saved files, Visual Studio will now lint JavaScript files as you edit, as well.
• Results can be reported for all JS files in your project, not just open files; if there are parts of your project you do not want to be linted, an .eslintignore file can now be used to specify directories and files that should be ignored.
• ESLint was updated to use ESLint 4 by default, but if your project has a local installation of ESLint, it will use that version instead.

ESLint may be disabled globally in Visual Studio by unchecking the Enable ESLint setting in the **Tools > Options > Text Editor > Javascript/Typescript > Linting ** (Figure 12).

Best Regards,

Brando
