dotnet ef CLI - Cannot find compatible framework version

Question

User960236597 posted

Hi, I am using the .NET command line tool for Entity framework, keying in

dotnet ef dbcontext info

It says cannot find compatible framework version. It is looking for Microsoft.NETCore.App version 3.1.1 but it detected a few versions including 2.1.14 which I am using.

How do I configure it to use 2.1.14 and resolve this error? Preferably without uninstalling because I might want to use the version in the future

You should be able to install 3.1.1 here,which should resolve this particular issue.

You are going to need to go within the properties of your application and choose .NET Core 2.1 as your preferred runtime, which should be an option since you have 2.1.14 installed.

You shouldn't need to install any of them unless you don't plan on using them moving forward. The installations will live side by side, and the only one that would possibly overwrite one another would be major point releases (e.g. 3.0 vs 3.1, etc.)

I configured global.json to use version 2.1.14:

{
  "sdk": {
    "version": "2.1.14"
  }
}

Then I got this error:
