The remote server returned an error: (400) Bad Request - Sharepoint

Question

Hi, I keep encountering the following error every time I try to log in to SharePoint using C# code:

'The remote server returned an error: (400) Bad Request.'

I've already followed all the steps outlined here 'https://learn.microsoft.com/en-us/answers/questions/1921238/how-to-upload-a-file-to-sharepoint?page=1&orderby=Helpful&comment=answer-1713065#newest-answer-comment'

and here [https://learn.microsoft.com/en-us/answers/questions/1922586/did-not-get-a-response-from-the-login-server-(idcr?page=1&orderby=Helpful&comment=answer-1781065](https://learn.microsoft.com/en-us/answers/questions/1922586/did-not-get-a-response-from-the-login-server-(idcr?page=1&orderby=Helpful&comment=answer-1781065)

I've been trying to resolve this issue for over a week and am running out of options.

Any help would be greatly appreciated

Hi @Braian Anderson,

The issue here might was that VS created console application as a .net core app, which as far as I'm aware does not work with the Microsoft.SharePoint.Client library. Please check if you created Console App(.Net Framework)
