I get an error when creating a new project with ASP.net Application (.NET Framework) format

Question

This is my error message interface, I have checked the complete files in Packages but the device still says these versions cannot be found. If I uninstall and reinstall VS, I still have the same problem

Answer 1

1. What version of Visual Studio e.g. VS2022 edition 17.18.0
2. Did you install Visual Studio to your C drive?

The following seems strange and what to focus on: The packages failed to install from I:\WindowsApps\Packages. Packages should be installed from NuGet unless cached under your user profile.

In regards to stuff like jQuery, look under the folder www/lib to see if there are libraries there.

Bottom line, if not using a preview edition of Visual Studio and Visual Studio is installed on your C drive, report this to Microsoft via the feedback/issue button, top right corner of Visual Studio.

Answer 2

my guess you have nuget configured to read from a file share. visual studio has no effect on this configuration. see:

Answer 3

Hi @THANH HUY ĐẶNG, 

Welcome to Microsoft Q&A!

Are you using Package Source Mapping? You can remove all package source mappings by going to Tools > Options > NuGet Package Manager > Package Source Mapping > Remove All. If it is added incorrectly, please correct it. 

You can create a new project and check that it is created properly. 

If it doesn’t work, please tell us your VS version and more details. 

Sincerely,

Anna
