Create a site-column of type user, multichoice and multiuser using Sharepoint Client Object Model

Question

I'm trying to create site-columns with following types: Text, Note, Number, Choice, User, MultiUser, MultiChoice

I've implemented it for all the types except for User, MultiChoice and MultiUser. Can't seem to find how to achieve it. This is what I've achieved so far.

StringBuilder choiceFieldGenericShema = new StringBuilder();
                choiceFieldGenericShema.Append("<Field Type='Choice' Format='Dropdown' Group='{1}' Name='{0}' DisplayName='{2}' Status='{3}' > <CHOICES> ");
                choiceFieldGenericShema.Append("</CHOICES>  </Field> ");
                string choicFieldSchema = string.Format(choiceFieldGenericShema.ToString(), columnItem.Title, columnItem.GroupName, columnItem.Name, columnItem.Status);
                var newField = web.Fields.AddFieldAsXml(choicFieldSchema, true, AddFieldOptions.DefaultValue);
                clientContext.Load(newField);
                clientContext.ExecuteQuery();

Can anyone please suggest a way following the above method to achieve my task? Thanks in advance!

I suggest you take a look at these articles:

In this case, you'll need to tweak with some attributes to toggle multi select for a choice + user field:

Choice:

<Field Type="MultiChoice" 
DisplayName="Labels_Selected" 
FillInChoice="FALSE" 
Group="Sample Site Columns" 
ID="{2fdf0ba7-0052-4e9f-80f6-e7669ac4ae4f}"
SourceID="http://schemas.microsoft.com/sharepoint/v3"
StaticName="LabelsSelected" Name="LabelsSelected"> 
</Field>

User:

<Field ID="{A0372EB5-A947-41CA-A5FA-A34C29D2FB88}"
Name="Employee"
DisplayName="Employee"
Type="UserMulti"
Required="TRUE"
StaticName="Employee"
UserSelectionMode="PeopleOnly"
Group="SampleGroup"/>

You can create site column using csom, below is code

string schemaChoiceField = "<Field ID='<GUID>' Type='Choice' Name='SideDishesChoice' StaticName='SideDishesChoice' 
   DisplayName='Side dishes' Format='RadioButtons'>"
   + "<Default>Patatoes</Default>"
   +         "<CHOICES>"
   +         "    <CHOICE>Fresh vegetables</CHOICE>"
   +         "    <CHOICE>Beans</CHOICE>"
   +         "</CHOICES>"
   + "</Field>";
