Windows Error Log:

Application 'EnterpriseReportsAPI' with physical root '...\Repos\InternalReportsAPI\EnterpriseReportsAPI' failed to load coreclr. Exception message: CLR worker thread exited prematurely
Process Id: 10688. File Version: 13.1.19350.1. Description: IIS ASP.NET Core Module V2 Request Handler. Commit: e276c8174b8bfdeb70efceafa81c75f8badbc8db

Every thing works more or less fine until I try to further the dependency injection by changing my static connectionstring helper into an injected service.

public class Connections : IConnections
    {
        private readonly ISecurityServiceHelper _securityServiceHelper;

        public Connections(ISecurityServiceHelper securityServiceHelper)
        {
            _securityServiceHelper = securityServiceHelper;
        }
        public string GetSqlConnectionString(string[] creds)
        {
            return _securityServiceHelper.GetSqlConnectionStringAsync(creds).Result;
        }
    }

Then in the startup.cs I change it to:

public Startup(IConfiguration configuration, IConnections connections)
        {
            Configuration = configuration;
            Connections = connections;
        }

        private readonly IConfiguration Configuration;
        private readonly IConnections Connections;

Then utilize those properties inside the following:

string[] creds =
            {
                        Configuration.GetSection("ApplicationCreds").GetSection("appId").Value,
                        Configuration.GetSection("ApplicationCreds").GetSection("appToken").Value,
                        Configuration.GetSection("ConnectionString").GetSection("connectionString").Value
            };
            services.AddDbContext<InternalReportsContext>(options =>
                options.UseSqlServer(Connections.GetSqlConnectionString(creds)));

I have declared the two services as follows:

services.AddScoped<IConnections, Connections>();

services.AddScoped<IConfiguration>(sp =>
            {
                IConfigurationBuilder configurationBuilder = new ConfigurationBuilder();
                configurationBuilder.AddJsonFile("appsettings.json");
                return configurationBuilder.Build();
            });

So I have looked at a few posts (notably [this])(HTTP Error 500.30 - ANCM In-Process Start Failure) on changing the InProcess to OutOfProcess however that gives me other weird issues. I am not sure what changes when I make these changes under the hood and it has been driving me crazy for several days.

I had started the API in 2.2 but it is now 3.1.1 and I removed all the 2.2 references from the csproj file as well.

If I change the properties to OutOfProcess as suggested by the other "related" post I get the following:

This seems to be very close to my issue but I can't figure out which reference has a dependency on the Core 2.2. I have removed all the 2.2 references from the csproj and I don't see anything that jumps out in my references. Or I am looking in the wrong place.
