Serilog sql server sink not writing messages - serilog

Question

-=-=-=-= Latest update
In my catch block, I brought up the exception variable in Quick Watch, and drilling down the inner exceptions showed me this error:
Unable to load DLL 'Microsoft.Data.SqlClient.SNI.x86.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
Problem is, in my bin\debug directory, that file is there!!! So why can it not be found? I tried but was not able to reference it directly.

A suggested answer below had some links which I re-examined. I picked out useful code, such as assigning my log object to the static logger, followed by a call to CloseAndFlush.
That showed me Microsoft.Data.SqlClient.dll errors when the CloseAndFlush call was executed. I used NuGet to update SQLClient, but still getting those errors:
Exception thrown: 'System.DllNotFoundException' in Microsoft.Data.SqlClient.dll
Exception thrown: 'System.TypeInitializationException' in Microsoft.Data.SqlClient.dll
I am now investigating those SQL.Client errors.

Working with Asp.NET, not core. Trying to get a basic sql server sink to work, having no luck. Something very simple must be the problem, but I can't see it.
Below is the table to write to, it already exists. With the seriuser account I can connect via SSMS, and perform all CRUD operations. I also wrote a method that uses SQL data objects that connects to the db and I can perform all CRUD operations on it that way also. But with Serilog, the log statement logs nothing. What could I be missing? The database is local on my machine. Breakpoint shows a valid logger object. Tried it also by passing in schemaname in sinkoptions, no luck. And no errors, had a try catch block around logger code previously.
A solution with a console app and a class library. Can't get much simpler than this.
The console app has this in program.cs:
class Program
{
static void Main(string[] args)
{
SLogger logger = new SLogger();
}
}
The class file and sql table:
public class SLogger
{
public SLogger()
{
var columnOption = new ColumnOptions();
columnOption.Store.Remove(StandardColumn.MessageTemplate);
ILogger log = new LoggerConfiguration()
.MinimumLevel.Verbose()
.WriteTo.MSSqlServer(#"Data Source=LW39\QA;Initial Catalog=DEV;user id=seriuser;Password=SERIUSER1;",
sinkOptions: new MSSqlServerSinkOptions { TableName = "Logs" },
columnOptions: columnOption)
.CreateLogger();
log.Information("Logger created.");
.....
.....
CREATE TABLE [dbo].[Logs](
[Id] [int] IDENTITY(1,1) NOT NULL,
[Message] [nvarchar](max) NULL,
[MessageTemplate] [nvarchar](max) NULL,
[Level] [nvarchar](128) NULL,
[TimeStamp] [datetime] NOT NULL,
[Exception] [nvarchar](max) NULL,
[Properties] [nvarchar](max) NULL,
CONSTRAINT [PK_Logs] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

Answer 1

Mentioned in my last update that I was receiving this error, which I beleived was the root cause of my problem:
Unable to load DLL 'Microsoft.Data.SqlClient.SNI.x86.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
and my confusion because said file was in the class library directory.
As I also mentioned, I had two projects in my solution: the class library and the test console app. Turns out the dll need to be in the bin directory of the console app!! Specifically in the x86 directory, which I had to create.
Once I placed the file there, the problem was solved. Thanks for all who helped!
