"Method not found" Issue with UseEncryptAttribute() Method in .NET 8 Upgrade

[srmomin]

I am currently in the process of upgrading my API from .NET 6 to .NET 8. As part of this project, we are using the AltairCA.EntityFrameworkCore.PostgreSQL.ColumnEncryption library (Version 6.0.2.3). During this upgrade process, I have updated all NuGet packages to their respective latest stable versions and upgraded all projects to target .NET 8. While trying to run the application, I encounter an error from the OnModelCreating() method when UseEncryptAttribute() method from your library is invoked.

Here is the relevant code snippet:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);
    var password = // Code to get encryption password
    modelBuilder.HasPostgresExtension("pgcrypto");
    modelBuilder.UseEncryptAttribute(password, EncKeyLength.L128);
}

The error message I receive is as follows:

Method not found: 'System.Collections.Generic.IEnumerable`1<Microsoft.EntityFrameworkCore.Metadata.IMutableProperty> Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType.GetProperties()'.

And here is the related stack trace:

AttributeExtension.UseEncryptAttribute(ModelBuilder builder, String password, EncKeyLength encKeyLength)
DirectoryDbContext.OnModelCreating(ModelBuilder modelBuilder)
ModelCustomizer.Customize(ModelBuilder modelBuilder, DbContext context)
ModelSource.CreateModel(DbContext context, IConventionSetBuilder conventionSetBuilder, ModelDependencies modelDependencies)
ModelSource.GetModel(DbContext context, ModelCreationDependencies modelCreationDependencies, Boolean designTime)
DbContextServices.CreateModel(Boolean designTime)
DbContextServices.get_Model()
...
...
...
IntegrationTest.CreateClient(String organisationId, String clientId, String clientName, String userId)
IntegrationTest.ExecuteTest(Func`2 request)
IntegrationTest.Get(String requestUri)

The error indicates that during the call to UseEncryptAttribute, there is an attempt to use a method called GetProperties() on IMutableEntityType from EF Core which cannot be found. Any guidance or suggestions regarding this issue would be greatly appreciated. Thank you for your time and help.

I upgraded the nuget package, please check if it's working now :)
