How to use multiple if/then in JSON schema - json.net

Question

I have a JSON schema defined as below -
{
"type": "object",
"properties": {
"prop1": {
"type": "string"
},
"prop2": {
"type": "string"
},
"prop3": {
"type": "string"
},
"prop4": {
"type": "string"
}
},
"anyOf": [
{
"if": {
"properties": {
"prop1": {
"const": "v1"
},
"prop2": {
"const": "v2"
}
}
},
"then": {
"required": [
"prop1",
"prop2",
"prop3"
]
}
},
{
"if": {
"properties": {
"prop1": {
"const": "v11"
},
"prop2": {
"const": "v22"
}
}
},
"then": {
"required": [
"prop1",
"prop2",
"prop4"
]
}
}
],
"required": [
"prop1",
"prop2"
]
}
A few scenarios i would like to validate -
{
"prop1": "aaa"
}
//should say prop2 is required --This works
{
"prop1": "aaa",
"prop2": "bbb"
}
//should validate to true --This works
{
"prop1": "v1"
"prop2": "v2"
}
//should say prop3 is required --This DOESN'T work
{
"prop1": "v11"
"prop2": "v22"
}
//should say prop4 is required --This DOESN'T work
Could someone please help me how to fix the above 2 test cases that doesnt work?

You need to change your anyOf to a allOf, to make sure both conditions are checked.
Due to the way you have written your if conditions, only one of them can be true at a time, so for one or the other of them (or both), the else clause will be executed, but you haven't provided an else clause, so it defaults to true, so at least one of the anyOf clauses will be true, so anyOf is true.
