I registered sample app from Microsoft graph sample app
And standard login is working but when I try to make it simplier by using this code:
var authContext = new AuthenticationContext(Settings.AzureADAuthority);
var token = authContext.AcquireToken(Settings.O365UnifiedAPIResource, new ClientCredential(Settings.ClientId, Settings.ClientSecret)).AccessToken;
I get the following error: Application with identifier '[ClientId here]' was not found in the directory microsoft.com
Setting.O365UnifiedAPIResource = @"https://graph.microsoft.com/";
Settings.AzureADAuthority = @"https://login.microsoftonline.com/common";
Does anyone know what can be the problem?

Settings.AzureADAuthority = @"https://login.microsoftonline.com/{tenant_id or tenant_name}";
When acquiring the token by using the client credential (client id + client secret). You should specify the tenant explicitly.
For example:
https://login.microsoftonline.com/{tenant_id}
or
https://login.microsoftonline.com/{your_domain.onmicrosoft.com}
BTW, as this registration will be for the sample app, it will only have the Mail.Send permission which is delegated permission. To acquire the app token, you also need to grant the app level permission in Azure AD since your are acquiring the app token rather than the user token.
