EF Core 8: Only the invariant culture is supported in globalization-invariant mode

[ttosello]

In .NET 8, using EntityFrameWorkCore, when I attempt to run the update-database command (with or without pending migration), the following error is thrown:

System.Globalization.CultureNotFoundException: Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information. (Parameter 'name') en-us is an invalid culture identifier. at System.Globalization.CultureInfo.GetCultureInfo(String name) at Microsoft.Data.SqlClient.SqlConnection.TryOpen(TaskCompletionSource1 retry, SqlConnectionOverrides overrides)

Removing the following from the Project file resolves the error:

<InvariantGlobalization>true</InvariantGlobalization>

@ttosello Can you provide a simple repro console app just with M.D.SqlClient?

Hi @ttosello, look for InvariantGlobalization property in your project setting and change it to false. I had the same issue and this solves it.

Having the same error. It worked @adeyinkaroyal, but I don't understand the error. It started at .NET 8.

@eduardscript it started at .NET 8 because that flag is now set by default in api templates (dotnet/aspnetcore#47066). Might be a good idea to raise this issue with aspnetcore folks.

@adeyinkaroyal I had the same problem when trying to Update-Database, with a project .net 8 and your solution works.

Duplicate of issue #220. Closing issue as it is by design

Just encase someone doesn't know how to change InvariantGlobalization . Make your you unload your project.

@ttosello I am using .net 8 and Entity Framework Core 8.0.0 versions in my project. When I made a request from api, I got the error in the image and it was solved by making the setting false in sdk. But I'm trying to understand something, is this problem caused by collation mismatch when connecting to the data with EF? Because the collation of the database I created in MSSQL DB is Turkish_CI_AS, I wanted to try changing it to a collation that supports en-us, but this was not a solution. I solved my problem but I don't understand the logic here. Someone explain for me.
