Hi, I’m liking the idea of the new Checkout API (it’s just what I need), and after following through the Quick Start guide using VS2019 and C#. I successfully tested in the sandbox and got back a response that I can use. This was a C# “Console Application” as per the example. But, and here is my pr…

:wave: What are the errors that you’re getting from Square? Also what’s your application Id? :slightly_smiling_face:

Hi Bryan, I don’t get as far as talking to the square server. My issue is inside VS2019, it looks like the Square SDK and some Microsoft Package/components are in conflict with each other. Sorry, what do you mean by Application ID (where is this from)? cheers

Do you have any more code we can look at? Or can you make a very small repro you can upload? Also you said you updated to .NET Framework 4.7.2. What were you on before? :slightly_smiling_face:

Hi, I am going to try starting from a new WEB Application project and see where that gets me, and I will post the code for that (plus list dependants, etc.). Unfortunately can’t do that till tomorrow (but appreciate your quick reply). I was on .NET Framework 4.6.x.

Sounds good! We’ll wait for the results. :slightly_smiling_face:

This is a Licensed version and…

Hi, my entire solution is now broken, after installing the Square SDK, despite installing ‘System.Collections’ I cannot get past this error:- System.BadImageFormatException: Cannot load a reference assembly for execution. [BadImageFormatException: Could not load file or assembly ‘System.Collect…

We checked everything and the team didn’t find actionable things on our side, it’s very likely related to the set up of the solution. The team has two suggestions: Try .NET 6 instead of .NET 4.6. It seems you are trying to mix with .NET standard. They suggest that you create a clean project and tr…

Hi Bryan, ok will do. Thanks. The repro had information in it I shouldn’t have shared, so made it private.
