Trying to add migration with .NET5 not working

[marzoukali]

Bug Description

I just upgraded from .Net core 3.1 to .Net 5 and I can see while typing dotnet --info in the cmd the below information:

To Reproduce

I migrated to .NET5 from 3.1 Core by following the below link:
https://docs.microsoft.com/en-us/aspnet/core/migration/31-to-50?view=aspnetcore-5.0&tabs=visual-studio

Now when I try to add migration or use any entityframework command even through the command line or visual studio package manager, I am getting the below error although i can see that I have already the SDK while running the dotnet --info command:

I tried to reinstall the SDK, runtime and update my windows 10 and visual studio 2019 but with no chance?

---

I am using:

• Windows 10
• Visual Studio 2019
• I've included the dotnet --info in the first attached image

Do you install the latest version of Microsoft.EntityframeworkCore.Tools? If not, this can be the cause.

@marzoukali What output do you get from running dotnet build?

Sorry guys we can close this now.

It was very wired. I just removed all my .NET Core SDKs and runtimes then installed .NET 5 as 32 bit instead of 64 and it works.
