NOTE: This is a sample application to help you understand how Semantic Kernel and AI can work in Web Applications. This sample is NOT FOR PRODUCTION deployments.//test2
This sample allows you to build your own integrated large language model (LLM) chat copilot. The sample is built on Microsoft Semantic Kernel and has three components:
- A frontend application React web app
- A backend REST API .NET web API service
- A .NET worker service for processing semantic memory.
These quick-start instructions run the sample locally. They can also be found on the official Chat Copilot Microsoft Learn documentation page for getting started.
To deploy the sample to Azure, please view Deploying Chat Copilot after meeting the requirements described below.
IMPORTANT: This sample is for educational purposes only and is not recommended for production deployments.
IMPORTANT: Each chat interaction will call Azure OpenAI/OpenAI which will use tokens that you may be billed for.
You will need the following items to run the sample:
- .NET 7.0 SDK (via Setup install.* script)
- Node.js (via Setup install.* script)
- Yarn (via Setup install.* script)
- Git
- AI Service (one of the following is required)
AI Service | Requirement |
---|---|
Azure OpenAI | - Access - Resource - Deployed models ( gpt-35-turbo and text-embedding-ada-002 ) - Endpoint - API key |
OpenAI | - Account - API key |

if using OpenAI. -
IMPORTANT: For
AzureOpenAI
, if you deployed modelsgpt-35-turbo
andtext-embedding-ada-002
with custom names (instead of the default names), also use the parameters:-CompletionModel {DEPLOYMENT_NAME} -EmbeddingModel {DEPLOYMENT_NAME}
Open the

Run Chat Copilot locally. This step starts both the backend API and frontend application.
.\Start.ps1
It may take a few minutes for Yarn packages to install on the first run.
NOTE: Confirm pop-ups are not blocked and you are logged in with the same account used to register the application.
-
(Optional) To start ONLY the backend:
.\Start-Backend.ps1

-
Open Bash as an Administrator.

Configure Chat Copilot.
-
For OpenAI
./configure.sh --aiservice OpenAI --apikey {API_KEY}
API_KEY
: TheAPI key
for OpenAI.
-
For Azure OpenAI
./configure.sh --aiservice AzureOpenAI \ --endpoint {AZURE_OPENAI_ENDPOINT} \ --apikey {API_KEY}
AZURE_OPENAI_ENDPOINT
: The Azure OpenAI resourceEndpoint
address.API_KEY
: TheAPI key
for Azure OpenAI.
IMPORTANT: If you deployed models
gpt-35-turbo
andtext-embedding-ada-002
with custom names (instead of the default names), you need to specify the deployment names with three additional parameters:./configure.sh --aiservice AzureOpenAI \ --endpoint {AZURE_OPENAI_ENDPOINT} \ --apikey {API_KEY} \ --completionmodel {DEPLOYMENT_NAME} \ --embeddingmodel {DEPLOYMENT_NAME}

Run Chat Copilot locally. This step starts both the backend API and frontend application.
./start.sh
It may take a few minutes for Yarn packages to install on the first run.
NOTE: Confirm pop-ups are not blocked and you are logged in with the same account used to register the application.
-
(Optional) To start ONLY the backend:
./start-backend.sh
-
(Optional) Run the memory pipeline
By default, the webapi is configured to work without the memory pipeline for synchronous processing documents. To enable asynchronous document processing, you need to configure the webapi and the memory pipeline. Please refer to the webapi README and the memory pipeline README for more information.
By default, Chat Copilot runs locally without authentication, using a guest user profile. If you want to enable authentication with Azure Active Directory, follow the steps below.
-
Create an application registration for the frontend web app, using the values below
Supported account types
: "Accounts in this organizational directory only ({YOUR TENANT} only - Single tenant)"Redirect URI (optional)
: Single-page application (SPA) and use http://localhost:3000.
-
Create a second application registration for the backend web api, using the values below:
Supported account types
: "Accounts in this organizational directory only ({YOUR TENANT} only - Single tenant)"- Do not configure a
Redirect URI (optional)
NOTE: Other account types can be used to allow multitenant and personal Microsoft accounts to use your application if you desire. Doing so may result in more users and therefore higher costs.
Take note of the
Application (client) ID
for both app registrations as you will need them in future steps.
-
Expose an API within the second app registration
-
Select Expose an API from the menu
-
Add an Application ID URI
-
This will generate an
api://
URI -
Click Save to store the generated URI

Issue: Unable to load chats.
Details: interactionin_progress: Interaction is currently in progress.
Explanation: The WebApp can display this error when the application is configured for a different AAD tenant from the browser, (e.g., personal/MSA account vs work/school account).
Solution: Either use a private/incognito browser tab or clear your browser credentials/cookies. Confirm you are logged in with the same account used to register the application.
-
Issue:: Challenges using text completion models, such as
text-davinci-003
Solution: For OpenAI, see model endpoint compatibility for the complete list of current models supporting chat completions. For Azure OpenAI, see model summary table and region availability.
-
Issue: Localhost SSL certificate errors / CORS errors
Explanation: Your browser may be blocking the frontend access to the backend while waiting for your permission to connect.
Solution:
- Confirm the backend service is running. Open a web browser and navigate to
https://localhost:40443/healthz
- You should see a confirmation message:
Healthy
- If your browser asks you to acknowledge the risks of visiting an insecure website, you must acknowledge this before the frontend can connect to the backend server.
- You should see a confirmation message:
- Navigate to
http://localhost:3000
or refresh the page to use the Chat Copilot application.
- Confirm the backend service is running. Open a web browser and navigate to
-
Issue: Yarn is not working.
Explanation: You may have the wrong Yarn version installed such as v2.x+.
Solution: Use the classic version.
npm install -g yarn yarn set version classic
-
Issue: Missing
/usr/share/dotnet/host/fxr
folder.Details: "A fatal error occurred. The folder [/usr/share/dotnet/host/fxr] does not exist" when running dotnet commands on Linux.
Explanation: When .NET (Core) was first released for Linux, it was not yet available in the official Ubuntu repo. So instead, many of us added the Microsoft APT repo in order to install it. Now, the packages are part of the Ubuntu repo, and they are conflicting with the Microsoft packages. This error is a result of mixed packages. (Source: StackOverflow)
Solution:
# Remove all existing packages to get to a clean state: sudo apt remove --assume-yes dotnet*; sudo apt remove --assume-yes aspnetcore*; sudo apt remove --assume-yes netstandard*; # Set the Microsoft package provider priority echo -e "Package: *\nPin: origin \"packages.microsoft.com\"\nPin-Priority: 1001" | sudo tee /etc/apt/preferences.d/99microsoft-dotnet.pref; # Update and install dotnet sudo apt update; sudo apt install --assume-yes dotnet-sdk-7.0;
Every release is associated with a release branch. For instance, release v0.9 is on a branch called 0.9. Once a release is out, its branch will no longer be updated. The exception to this is the latest release branch, which will only receive bug fixes. This is to provide some stability to those for whom breaking changes and being on the bleeding edge (with the bugs it can entail) is not a desirable option.
