How to fix Command dotnet ef not found on Visual Code on MacOS

The issue you're encountering in Visual Studio Code (VS Code) involves two parts: a notification about the default shell and an error with the dotnet ef command

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET program, but dotnet-ef does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

Explanation:

  • The dotnet ef command is part of the Entity Framework Core CLI, used for managing migrations, databases, etc.
  • The error occurs because the dotnet-ef tool is not found. Possible reasons:
    1. The dotnet-ef tool is not installed.
    2. The tool is installed but not in the system PATH.
    3. The .NET SDK version is incompatible.

Install the dotnet-ef tool, run the following command:

.NET 9

dotnet tool install --global dotnet-ef --version 9.*

.NET 8

dotnet tool install --global dotnet-ef --version 8.*

.NET 7

dotnet tool install --global dotnet-ef --version 7.*

.NET 6

dotnet tool install --global dotnet-ef --version 6.*

.NET 5

dotnet tool install --global dotnet-ef --version 5.*

.NET Core 3

dotnet tool install --global dotnet-ef --version 3.*
