dataverse for teams & vscode how to link??

Hi bingqiling,

According to the article "Creating a native Teams app with Dataverse integration" by Jan de Vries, to connect to the Microsoft Dataverse REST API in a native Teams app, you need to:

1. Get the Web API endpoint for your environment. You can do this by navigating to the environment in the browser and searching for the Developer resources in settings.
2. Create a JWT bearer token with the user_impersonation scope for Dynamics 365. To do this, you can use the following code:

private string dynamicsResource = "https://[thePowerPlatformEnvironment].api.crm4.dynamics.com/";
private string dynamicsScope = "user_impersonation";

private async Task ConsentAndShow()
{
    try
    {
        await teamsUserCredential.LoginAsync(new[] { _scope, dynamicsResource + dynamicsScope });
        NeedConsent = false;
        await ShowProfile();
        await ShowDynamicsUserId();
    }
    catch (ExceptionWithCode e)
    {
        ErrorMessage = e.Message;
    }
}

1. Add the token to the Authorization header of your requests to the Dataverse REST API.

For example, to query the accounts in Dataverse, you could use the following code:

private async Task LoadDataverseData()
{
    var dynamicsToken = (await teamsUserCredential.GetTokenAsync(new TokenRequestContext(new string[] { dynamicsResource + dynamicsScope}), new System.Threading.CancellationToken())).Token;
    var httpClient = HttpClientFactory.CreateClient();
    httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", dynamicsToken);
    var accountsResponse = await httpClient.GetAsync(dynamicsResource + "/api/data/v9.2/accounts?$select=name,revenue&$orderby=revenue desc&$top=3");

    if (accountsResponse.IsSuccessStatusCode)
    {
        var topAccountsWithRevenue = await JsonSerializer.DeserializeAsync<Models.Dataverse.Accounts.WithRevenue.Rootobject>(
                                        await accountsResponse.Content.ReadAsStreamAsync());
        _accountCollection.Clear();
        _accountCollection.AddRange(topAccountsWithRevenue.value);
    }
    else
    {
        ErrorMessage += "Web API call failed";
        ErrorMessage += "Reason: " + accountsResponse.ReasonPhrase;
    }
}
