public TEntity GetById(Guid id)
{
return _entities.Find(id);
}/// <summary>
/// Get all records.
/// </summary>
/// <returns></returns>
public IEnumerable<TEntity> GetAll()
{
return _entities.ToList();
}4 days back, I updated my entity framework version from 6.4.0 to 6.4.4 ( is this causing any issue)

2021-05-25T21:47:37.7+00:00 EF is already using the Repository pattern, and the usage of the generic Repository over EF is not optimal. I avoid using the generic repository. I don't know you changing to framework 6.4.0 is causing problems. Does EF have a 6.4.4 version?

2021-05-28T10:58:40.137+00:00 Thank you so much for all your valuable inputs. @Duane Arnold @AddWebSolution
The root cause of the issue was due to this below-mentioned line was missing from the windows service startup file,
Environment.SetEnvironmentVariable("AppendManifestToken_SQLiteProviderManifest", ";BinaryGUID=True;");
Mistakenly it got removed and created big chaos in the application.
