B4.2 not fully interoperable with 4.1

Hi,

It's not a GUID problem, cTrader 4.2 uses new SDK style projects and cTrader 4.1 uses old legacy style projects, these two aren't compatible with each other.

Here is an example of cTrader 4.2 .NET framework cBot project file:

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net40</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="cTrader.Automate" Version="1.*" />
  </ItemGroup>
</Project>

And cTrader 4.1 cBot project file:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

cTrader 4.2 can use and build cTrader 4.1 cBots/Indicators, but cTrader 4.1 can't.

Your answer does not adress algos barred from compile under 4.1 after being compiled under 4.2. It might be solved by calling  4.1 XML snippet from 4.2,  not its 4.2 version.

Actualy all algos complied under 4.2 must be re-sourced from scratch under 4.1 in order to compile. 

Actually compiling under 4.2 targeting 4.1  brings this csprojj XML. This denied when compiling under 4.1.

RE:

Hi,

As I said on my first post, the cBots/indicators that are compiled in cTrader 4.2 is not compatible with cTrader 4.1, the compatibility is one side, you can build cTrader 4.1 indicators/cBots on cTrader 4.2 but not vice versa.
