The framework 'Microsoft.AspNetCore.App', version '3.1.3' was not found

Question

After upgrading targetFramework for my web app from dotnet-core-2.2 to dotnet-core-3.1.2 on another developer machine we are getting following error

It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '3.1.3' was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=3.1.3&arch=x64&rid=win10-x64

We have tried several approaches to solve the issue

• Downloaded and install the dotnet core from specified link in error
• Downloaded runtime from the link https://dotnet.microsoft.com/download/dotnet-core/3.1
• Uninstalled the other dotnet core framework version other than 3.1.2 or 3.1.3

still we are facing the same issue, please guide me to troubleshoot this issue.

Answer 1

I solved the problem by installing the Hosting bundle from here.

Answer 2

I have posted same question on github dotnet issues page, the user vitek karas provided me the lead that x64 runtime C:\ProgramFiles\dotnet\shared\Microsoft.AspNetCore.App\3.1.3 folder was missing.

Then I tried reinstalling SDK 3.1.201 still folder was missing.

I also tried install aspnetcore-runtime-3.1.3 X64 still folder was missing.

finally I have downloaded dotnet-sdk-3.1.201-win-x64.zip and copied Microsoft.AspNetCore.App\3.1.3 folder manually from the zip file to C:\ProgramFiles\dotnet\shared\Microsoft.AspNetCore.App\3.1.3 then my asp.net core application started working .
