Steps to Reproduce

1. Create blip int testBlip = createyourblip
2. Then try delete blip using RemoveBlip(out testblip);
3. Log.Info(testBlip) will show value (i assume its the handle) but will not be removed.
4. Same as RemoveObject(out object) client sided though transferring of network object to server, will remove object or props

Expected Behavior

Blip should be removed on client sided

Actual Behavior

Blip was not removed on client sided

EDIT: Please disregard this comment and see below since this appears to be related specifically to .NET

I wasn't able to replicate this in Lua. Is this perhaps exclusive to a runtime? If so, they will probably need more data and a test resource would be helpful.
Here's what I tried(resource attached, just extract and start test):

local blips = {}

---@param coords vector3
---@return number
function CreateBlip(coords)
	local blip = AddBlipForCoord(coords)

	SetBlipSprite(blip, 671)
	SetBlipScale(blip, 1.0)
	SetBlipColour(blip, 25)
	SetBlipDisplay(blip, 4)
	SetBlipAsShortRange(blip, true)

	BeginTextCommandSetBlipName("STRING")
	AddTextComponentString("Test Blip")
	EndTextCommandSetBlipName(blip)

	return blip
end

RegisterCommand("addblip", function()
    local coords = GetEntityCoords(PlayerPedId())
    table.insert(blips, CreateBlip(coords))
end, false)

RegisterCommand("removeblips", function()
    for i=1, #blips do
        print("Attempting to remove blip with id: "..blips[i])
        RemoveBlip(blips[i])
    end
end, false)

Forgot to mentioned its C# client sided

I think there's a problem with the out version of the native in the C# code (E.g. public static void RemoveBlip(out int blip)).
By creating a Ref<int> and passing that in I was able to use the other override public static void RemoveBlip(Ref<int> blip) without issue.

Broken example:

[OnCommand("testblips")]
public static async void OnTestMarkerNull()
{
    if (API.Players.Local.Ped == null) return;
    
    var pedLoc = API.Players.Local.Ped.Position;
    var blip = Native.AddBlipForCoord(pedLoc.X, pedLoc.Y, pedLoc.Z);
    API.Log.Debug($"Created blip {blip} at {pedLoc}");

    await Task.Delay(2500);
    Native.RemoveBlip(out blip); // Value of `blip` is never actually accessed in the Native code
    API.Log.Debug($"Removed blip {blip}"); // Prints 0, but blip wasn't deleted
}

Working example code:

[OnCommand("testblips")]
public static async void OnTestMarkerNull()
{
    if (API.Players.Local.Ped == null) return;
    
    var pedLoc = API.Players.Local.Ped.Position;
    var blip = Native.AddBlipForCoord(pedLoc.X, pedLoc.Y, pedLoc.Z);
    API.Log.Debug($"Created blip {blip} at {pedLoc}");

    await Task.Delay(2500);
    var blipRef = new Ref<int>(ref blip); // Create Ref of our blip AFTER await as Ref<int> doesn't survive the async await
    Native.RemoveBlip(blipRef);
    API.Log.Debug($"Removed blip {blipRef.Value}"); // Prints 0 since the blip is deleted?
}

Looking at the assemblies:

public static void RemoveBlip(out int blip) // Never accessed a value
 {
   Native.nativeApi.ResetContext();
   Native.nativeApi.PushArg<int>(0); // ERROR here maybe? Should probably use a blip ID here instead of 0
   int num = (int) Native.nativeApi.Invoke(18326475465518923026UL, nameof (RemoveBlip));
   blip = Native.nativeApi.GetResInt(1);
 }

[MrGonzy]

Agreed. Probably it was resetted to 0 before being deleted

Looking at the assemblies:

public static void RemoveBlip(out int blip) // Never accessed a value
 {
   Native.nativeApi.ResetContext();
   Native.nativeApi.PushArg<int>(0); // ERROR here maybe? Should probably use a blip ID here instead of 0
   int num = (int) Native.nativeApi.Invoke(18326475465518923026UL, nameof (RemoveBlip));
   blip = Native.nativeApi.GetResInt(1);
 }

out int does not work with DeleteEntity also..

[MrGonzy]

Yes apparently doesnt work. DeleteObject too doesnt work

[dBozee]

Pretty much any native that should be expected to take an out var with no other params will be non-functional it seems.
