I have recently got a Mac M1, I have to build a Microservice based Web API application on Asp.net Core using EF & SQL Server.

I added EntityFrameworkCore(5.0.11) through NuGet Package successfully. The sdk & runtime installed details on my Mac is:

.NET SDKs installed:
- 6.0.101
.NET runtimes installed:
- Microsoft.AspNetCore.App 6.0.1 
- Microsoft.NETCore.App 6.0.1

Firstly , I was not able to install SQL Server 2019 on Mac but after searching I found a solution for that by installing SQL Edge on Docker & connecting to Azure Data Studio and it's working fine.

Now the problem is I am not able to run EFcore migration add initial, Update Database through Entity Framework. I searched everywhere but whenever I am executing these command, I am getting following error:

Build started... Build succeeded. It was not possible to find any
compatible framework version The framework 'Microsoft.AspNetCore.App',
version '3.1.0' (arm64) was not found.
 - The following frameworks were found: 6.0.1 
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=3.1.0&arch=arm64&rid=osx.12-arm64.

I did install the above framework but that is x64. And still EF command are not working and I am not able to update the database. Is there any solution for this? Does EFCore work on Mac M1 machines?

The reason is that ef tool is not able to find the correct arch for now. A workaround is to force ef tool to use the latest runtime found on your machine.

export DOTNET_ROLL_FORWARD=LatestMajor

export the above env var and run dotnet ef xxx again.

Update

This fixes the problem permanently:

dotnet tool uninstall dotnet-ef -g
dotnet tool install dotnet-ef -a arm64 -g

You can also install EF tool locally

CD to your source directory and do this:

dotnet new tool-manifest
dotnet tool install  dotnet-ef

In this way, it works with the .Net 5/6 arm64.

There's a bug in the arm64 version installer that references the x64 version of EF Core.

Try to install proper SDK version manually from this link.

You need to use the sdk version for your cli,.NET 5 and below installs in a different directory and from your output looks like you cli points to .NET 6. You should install the ef tools locally like so

dotnet new tool-manifest # if you are setting up this repo
dotnet tool install --local dotnet-ef --version 5.0.15

then,

/usr/local/share/dotnet/x64/dotnet ef migrations add initialCreate -s ../API -o Migrations

You can shorten the path by using this article https://dev.to/smiththe_4th/use-multiple-net-sdk-cli-commands-on-mac-m1-64j
