下面是一些有关如何解决此问题的简单代码.我必须提供主机租户(请参见下面的代码.

Here is some rough and ready code on how I solved this. I had to supply the host tenant (see in the code below.

    private async Task<string> SqlServerVersion()
    {
        var provider = new AzureServiceTokenProvider();
        var token = await provider.GetAccessTokenAsync("https://database.windows.net/", "<host tenant>.onmicrosoft.com").ConfigureAwait(false);

        SqlConnectionStringBuilder csb = new SqlConnectionStringBuilder
        {
            csb.DataSource = "<your server>.database.windows.net";
            csb.InitialCatalog = "<your database>";
        };

        using (var conn = new SqlConnection(csb.ConnectionString))
        {
            conn.AccessToken = token;
            await conn.OpenAsync().ConfigureAwait(false);

            using (var sqlCommand = new SqlCommand("SELECT @@VERSION", conn))
            {
                var result = await sqlCommand.ExecuteScalarAsync().ConfigureAwait(false);
                return result.ToString();
            }
        }
    }
