Hi,
Why is this code for setting up an imperfection analysis not working?
```auto
var imperfectionSettings = new Calculate.Imperfection
(
loadCombinations,
new List { 5 },
true,
5,
true
);
analysis = new Analysis(imperfection: imperfectionSettings, calcImpf: true);
connection.RunAnalysis(analysis);
```
I get the following exception:

Hi @dfepe !
I have found an issue in the analysis setting in our code.
Can you get the latest source code from the branch 23.7.0 ?
I have just done a commit which should solve the issue

The dev channel is not available through nuget. Could you write some simple instructions to install the API downloading the github repository? I find it a bit difficult

Sure! Are you using Visual Studio? if so,
Navigate to:
> **[GitHub - strusoft/femdesign-api at 23.7.0\_Dev](https://github.com/strusoft/femdesign-api/tree/23.7.0_Dev)**
>
> 23.7.0\_Dev
click on `code` and download [.zip](https://github.com/strusoft/femdesign-api/tree/23.7.0_Dev)
In your project Visual Studio project, you can now add the `FemDesign.Core.csproj`
I would also suggest to download “GitHub desktop” to make this process easier 🙂

Thank you! I normally use Visual Studio Code, but it should work in a similar way.

I actually tried it before in VSCode and this was the problem:
Do you know any solution for it?

what happen if you click on `Use C# Extension` ? It should work out of the box 🙂
I have found a thread about the topic. It seems that our team can do some work related to the SDK-style

Then the solution explorer is not available so I don’t know how to add existing projects. I also get problems with other libraries and references, like the Newtonsoft.

All right 🙂
add the following .dll to your project and it will work. I have compiled the .dll of this temporary version for you.
