Hi there, Chris 👋🏻 I'm August from the GrowthBook team. We had a customer recently ask about the C# SDK and I wanted to post their question here in case you can answer it.

I’m attempting to add the GrowthBook.dll into a Unity/C# project we have, it successfully builds in the Unity editor, however on Android builds it runs into problems.

I’ve imported GrowthBook.dll in Assets/Plugins

I reference the GrowthBook namespace and am able to access the types and classes in the GrowthBook.dll in the Unity editor, however as soon as it’s on a device it no longer works, is this dll compatible with Android/iOS?

Do you have any other customers who’ve attempted something similar?

Hello everyone, I have a query regarding the

GetFeatureValue

method in GrowthBook when testing with C# in LINQPad. Executing the command ``gb.GetFeatureValue("test", default(bool?)).Dump();`` yields different outcomes depending on the default feature value. Specifically, if the feature's default is set to true, the result is as expected: true. However, when the default is set to false, the result is unexpectedly null, which seems illogical, especially since the production environment is active. Adding to the confusion, the response from the request indicates the default value as null, which contradicts the expected behavior. Here's the response snippet for clarity: ``{"status":200,"features":{"test":{"defaultValue":false},"gbdemo-checkout-layout":{"defaultValue":"current","rules":[{"condition":{"is_employee":true},"force":"dev"},{"coverage":1,"seed":"gbdemo-checkout-layout","hashVersion":2,"variations":["current","dev-compact","dev"],"weights":[0.3334,0.3333,0.3333],"key":"gbdemo-checkout-layout","meta":[{"key":"0","name":"Current"},{"key":"1","name":"Dev-Compact"},{"key":"2","name":"Dev"}],"phase":"0","name":"gbdemo-checkout-layout"}]}},"dateUpdated":"2024-02-21T145528.321Z"}``. This discrepancy is baffling and I'm looking for insights or explanations.

Good morning all. I've been integrating the sdk with our codebase and wanted to get some clarity on whether there's an issue with our setup or an issue in the sdk itself. The situation is where we have a forcing rule and a tracking callback configured. This causes a null ref ex in this code due to rule.Tracks being null

I can't see anywhere in the front end which would allow us to define this collection for a forced rule

This is our configuration code for setting up the growthbook instance

Adding a null check before rule.Tracks resolves this issue but it would be good to know how we would setup a rule with tracking information. Thanks!

C# SDK has been updated - 1.0.5 https://github.com/growthbook/growthbook-c-sharp and https://www.nuget.org/packages/growthbook-c-sharp/ - Big thanks to @magnificent-twilight-21363 for his work on this!

Dear Team, I am new to GrowthBook and am currently setting it up locally. We plan to use it with Sitecore CMS. I am trying to set it up in an ASP.NET framework using the pipeline. I have already installed the NuGet package with the following details:

<package id="growthbook-c-sharp" version="1.0.5" targetFramework="net48" />

. However, I am encountering an error stating that the relevant method cannot be found. Can you please help me resolve this issue?

Hello everyone, I integrated growthbook into my project. My backend is in .NET and my database is postgreSQL. When I released it to production, my response times went through the roof. Any recommendations you can give me? I think I skipped something in the documentation 😞

I have another question about the SDK: I have it set up in a way that it should receive the changes from the API, which I can see is happening in the logs. This config was not document anywhere so I may have set it up incorrectly. However, the value of the flag does not change, so it continues to evaluate to

true

even though I set it to

false

. I create a Singleton instance that I make available to DI:

var context = new GrowthBook.Context
{
   Enabled = true,
   ClientKey = "sdk-...",
   LoggerFactory = loggerFactory
};

_gb = new GrowthBook.GrowthBook(context);
_gb.LoadFeatures();

These are the logs indicating that it received the feature change.

info: GrowthBook.Api.FeatureRefreshWorker[0]
      API response JSON contained no encrypted features, returning '1' unencrypted features
info: GrowthBook.Api.FeatureRefreshWorker[0]
      Cache has been refreshed with server sent event features
info: GrowthBook.Api.FeatureRefreshWorker[0]
      Making an HTTP request to server sent events endpoint '<https://cdn.growthbook.io/sub/sdk-...>'
info: GrowthBook.Api.FeatureRefreshWorker[0]
      API response JSON contained no encrypted features, returning '1' unencrypted features
info: GrowthBook.Api.FeatureRefreshWorker[0]
      Cache has been refreshed with server sent event features

This is how I evaluate the flag on the GrowthBook instance injected via DI:

_gb.Attributes["workspaceId"] = workspaceId.ToString();
 return _gb.IsOn(key);

As I said, the value of the flag only changes after I restart the service.

Hi Team, a customer is trying to set up the C# server side SDK. Do you have an example with the SDK fetching the flags from the API and refreshing them? This seems to be supported in code but not documented.

Where do you see 1.0.2? In Growthbook portal, while creating a sdk connection?

Hey Team, what is the syntax for the trackingCallback in C#? I can't find it documented here or here. Customer query in screenshot

Hello, is anyone aware of how to fix this? https://github.com/growthbook/growthbook-c-sharp/issues/36

is it possible to collaborate for the c# SDK? are you guys accepting pull-requests?
