Scaffold-DbContext - CultureNotFoundException: Only the invariant culture is supported in globalization-invariant mode. par'name' en-us is an invalid

Scaffold-DbContext "connection string" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Entities 

I am running the command above and I get the following error, tried both with .NET 7 and 8 preview.

I even added <InvariantGlobalization>true</InvariantGlobalization> to project but that didn't do anything.

<PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <InvariantGlobalization>true</InvariantGlobalization>
</PropertyGroup>

You have to make changes in .csproj file of your project, need to add InvariantGlobalization attribute to false in PropertyGroup.

This is how it looks.

<PropertyGroup>
  <TargetFramework>net8.0</TargetFramework>
  <ImplicitUsings>enable</ImplicitUsings>
  <InvariantGlobalization>false</InvariantGlobalization>
</PropertyGroup>

Check your .csproj file; ensure the following line is added within the <PropertyGroup></PropertyGroup> section: <InvariantGlobalization>false</InvariantGlobalization>

If it is not available, add the line to fix the issue. If available, ensure it is set to false.

Example .csproj entry:

<PropertyGroup>
  <InvariantGlobalization>false</InvariantGlobalization>
