Unable to retrieve project metadata. Ensure it's an SDK-style project

Question

I have a solution that is made up of 4 projects as shown in the screenshot

The DbContext is inside NewKyc.Data project. The startup project is NewKyc

The ConfigureServices method of the Startup.cs contains the following block

services.AddDbContext<AppDbContext>(
           dbContextOptions => dbContextOptions
              .UseMySql(Configuration["ConnectionStrings:MySQLConnection"], 
              new MySqlServerVersion(new Version(mysql_version[0], mysql_version[1], mysql_version[2])), b=>b.MigrationsAssembly("NewKyc")

To add migrations, I write the following

dotnet ef migrations add EntityRelationshipsReview --startup-project "../NewKyc.csproj" --context AppDbContext --verbose

and I get the following messages

MSBUILD : error MSB1009: Project file does not exist. Switch: /Users/mac/Documents/Projects/folder/subfolder/subsubfolder/NewKyc.csproj

And this

Unable to retrieve project metadata. Ensure it's an SDK-style project. If you're using a custom BaseIntermediateOutputPath or MSBuildProjectExtensionsPath values, Use the --msbuildprojectextensionspath option.

Where am I getting it wrong?

It is a .NET Core 3.1 project upgraded to .NET 6

Answer 1

Since you've upgraded from Net Core 3.1 to 6.0 it's possible your dotnet-ef CLI tool is out of date, you can update it globally, according to the docs, using the following command:

dotnet tool update -g dotnet-ef

Or locally:

dotnet tool update --local dotnet-ef
