• Since C# 7.1, you can make the Main method async.
• You can return the exit code directly, rather than using Environment.Exit.
• You should avoid throwing an exception if the URL in the config file is invalid.
• You should wrap the HttpResponseMessage in a using block.
• There's no point in the reasoncode and httpReasonStatus variables, since you never use them.
• Console applications should generally return 0 if they succeed, and non-zero if they fail. The non-successful HTTP status code looks like a good candidate here.

but it's not working and i'm guessing it is not working because you cannot query with parameter "Images", in the database is stored as a blob. So im guessing i have to convert List to something else that is more easily supported in sqlite.

In my application every template has 5 images, but this might change in the future. What is the correct approach according to DB design, to have a TemplateImage object with 5 images or to have only one image for every TemplateImage object like this:

however the GetSequenceHashCode doesnt work as expected, it gives different results on every run, so i will have to check with another code.

But looks very bad to me, will this have impact on performance? is there any other way for the same result?

Quote:

You could combine those five queries into one. Something like "SELECT Id FROM TemplateImages WHERE ImageHash IN (@value1, @value2, @value3, @value4, @value5". If the values already exist in the table, such a query would give you their Id's.

var result = DatabaseHelper.db().Query<TemplateImage>("Select * from TemplateImages where Image=?", images[0]);

So the question is, how i can md5 List<templateimage>? (or another consistent hash)

If i can find a single query that can do that for all the images, i think im good
