Setup

Install prerequisites

The following software must be installed:

1. .NET Core SDK version SDK 3.1.100 or later
2. Visual Studio 2019 version 16.4 or later with the following workloads:
   1. ASP.NET and web development
   2. Azure development

Provision Azure resources

1. Open the Azure Cloud Shell in your web browser.

2. Run the following command to configure your Azure CLI defaults for resource group and region:

   az configure --defaults group=<resource_group_name> location=<region_name>

3. Run the following command to provision an Azure Storage account:

   az storage account create --name <storage_resource_name>

4. Run the following command to provision an Azure SignalR Service instance:

   az signalr create --name <signalr_resource_name> --sku Standard_S1 --service-mode Serverless

Configure the Azure Functions project

1. Create a new local.settings.json file in the root of the ContosoLending.LoanProcessing project with the following content:

   {
     "IsEncrypted": false,
     "Values": {
   	"AzureSignalRConnectionString": "<signalr_connection_string>",
   	"AzureWebJobsStorage": "<storage_connection_string>",
   	"FUNCTIONS_WORKER_RUNTIME": "dotnet"
     },
     "Host": {
   	"CORS": "https://localhost:44364",
   	"CORSCredentials": true,
   	"LocalHttpPort": 7071
     }
   }

2. From the Azure Cloud Shell, run the following command to get the Azure Storage account's connection string:

   az storage account show-connection-string --name <storage_resource_name> --query connectionString

   Copy the resulting value (without the double quotes) to your clipboard.

3. Replace "<storage_connection_string>" in local.settings.json with the value on your clipboard.

4. Run the following command to get the Azure SignalR Service's connection string:

   az signalr key list --name <signalr_resource_name> --query primaryConnectionString

   Copy the resulting value (without the double quotes) to your clipboard.

5. Replace "<signalr_connection_string>" in local.settings.json with the value on your clipboard.

CurrencyExchange project Target Framework

Hi Scott- great project (mind blown)...
just wondering if there was a reason to leave the CurrencyExchange project (gRPC) on version netcoreapp3.0?
