The following table outlines projects found in the solution. 4 | 5 | |Project |Description | 6 | |---------------------------------|------------------------------------------------------| 7 | |*ContosoLending.CurrencyExchange*|gRPC project handling currency conversion | 8 | |*ContosoLending.DomainModel* |.NET Standard project containing shared models | 9 | |*ContosoLending.LoanProcessing* |Durable Functions project for handling loan processing| 10 | |*ContosoLending.Ui* |Server-side Blazor UI project | 11 | 12 | ## Setup 13 | 14 | ### Install prerequisites 15 | 16 | The following software must be installed: 17 | 18 | 1. [.NET Core SDK version SDK 3.1.100 or later](https://dotnet.microsoft.com/download/dotnet-core/3.1) 19 | 1. [Visual Studio 2019 version 16.4 or later](https://visualstudio.microsoft.com/downloads/) with the following workloads: 20 | 1. **ASP.NET and web development** 21 | 1. **Azure development** 22 | 23 | ### Provision Azure resources 24 | 25 | 1. Open the [Azure Cloud Shell](https://shell.azure.com) in your web browser. 26 | 27 | 1. Run the following command to configure your Azure CLI defaults for resource group and region: 28 | 29 | ```bash 30 | az configure --defaults group= location= 31 | ``` 32 | 33 | 1. Run the following command to provision an Azure Storage account: 34 | 35 | ```bash 36 | az storage account create --name 37 | ``` 38 | 39 | 1. Run the following command to provision an Azure SignalR Service instance: 40 | 41 | ```bash 42 | az signalr create --name --sku Standard_S1 --service-mode Serverless 43 | ``` 44 | 45 | ### Configure the Azure Functions project 46 | 47 | 1. Create a new *local.settings.json* file in the root of the *ContosoLending.LoanProcessing* project with the following content: 48 | 49 | ```json 50 | { 51 | "IsEncrypted": false, 52 | "Values": { 53 | "AzureSignalRConnectionString": "", 54 | "AzureWebJobsStorage": "", 55 | "FUNCTIONS_WORKER_RUNTIME": "dotnet" 56 | }, 57 | "Host": { 58 | "CORS": "https://localhost:44364", 59 | "CORSCredentials": true, 60 | "LocalHttpPort": 7071 61 | } 62 | } 63 | ``` 64 | 65 | 1. From the Azure Cloud Shell, run the following command to get the Azure Storage account's connection string: 66 | 67 | ```bash 68 | az storage account show-connection-string --name --query connectionString 69 | ``` 70 | 71 | Copy the resulting value (without the double quotes) to your clipboard. 72 | 73 | 1. Replace "<storage_connection_string>" in *local.settings.json* with the value on your clipboard. 74 | 75 | 1. Run the following command to get the Azure SignalR Service's connection string: 76 | 77 | ```bash 78 | az signalr key list --name --query primaryConnectionString 79 | ``` 80 | 81 | Copy the resulting value (without the double quotes) to your clipboard. 82 | 83 | 1. Replace "<signalr_connection_string>" in *local.settings.json* with the value on your clipboard. 84 | 85 | ## Testing 86 | 87 | 1. Open the solution file (*src\ContosoLending.sln*). 88 | 1. In **Solution Explorer**, right-click the *libman.json* file in the **ContosoLending.Ui** project > **Restore Client-Side Libraries**. 89 | 1. In **Solution Explorer**, right-click the solution name > **Properties**. 90 | 1. Select the **Multiple startup projects** radio button, and configure the solution as follows: 91 | 92 | ![multiple project launch configuration in Visual Studio](https://user-images.githubusercontent.com/10702007/68152936-39716780-ff0a-11e9-9f62-babf2267ef77.png) 93 | 94 | 1. Select the **OK** button. 95 | 1. Select the **Start** button next to the **<Multiple Startup Projects>** launch configuration drop-down list. 96 | -------------------------------------------------------------------------------- /src/.gitignore: -------------------------------------------------------------------------------- 1 | ## Ignore Visual Studio temporary files, build results, and 2 | ## files generated by popular Visual Studio add-ons. 3 | 4 | # Azure Functions localsettings file 5 | local.settings.json 6 | 7 | # User-specific files 8 | *.suo 9 | *.user 10 | *.userosscache 11 | *.sln.docstates 12 | 13 | # User-specific files (MonoDevelop/Xamarin Studio) 14 | *.userprefs 15 | 16 | # Build results 17 | [Dd]ebug/ 18 | [Dd]ebugPublic/ 19 | [Rr]elease/ 20 | [Rr]eleases/ 21 | x64/ 22 | x86/ 23 | bld/ 24 | [Bb]in/ 25 | [Oo]bj/ 26 | [Ll]og/ 27 | 28 | # Visual Studio 2015 cache/options directory 29 | .vs/ 30 | # Uncomment if you have tasks that create the project's static files in wwwroot 31 | **/wwwroot/lib/ 32 | 33 | # MSTest test Results 34 | [Tt]est[Rr]esult*/ 35 | [Bb]uild[Ll]og.* 36 | 37 | # NUNIT 38 | *.VisualState.xml 39 | TestResult.xml 40 | 41 | # Build Results of an ATL Project 42 | [Dd]ebugPS/ 43 | [Rr]eleasePS/ 44 | dlldata.c 45 | 46 | # DNX 47 | project.lock.json 48 | project.fragment.lock.json 49 | artifacts/ 50 | 51 | *_i.c 52 | *_p.c 53 | *_i.h 54 | *.ilk 55 | *.meta 56 | *.obj 57 | *.pch 58 | *.pdb 59 | *.pgc 60 | *.pgd 61 | *.rsp 62 | *.sbr 63 | *.tlb 64 | *.tli 65 | *.tlh 66 | *.tmp 67 | *.tmp_proj 68 | *.log 69 | *.vspscc 70 | *.vssscc 71 | .builds 72 | *.pidb 73 | *.svclog 74 | *.scc 75 | 76 | # Chutzpah Test files 77 | _Chutzpah* 78 | 79 | # Visual C++ cache files 80 | ipch/ 81 | *.aps 82 | *.ncb 83 | *.opendb 84 | *.opensdf 85 | *.sdf 86 | *.cachefile 87 | *.VC.db 88 | *.VC.VC.opendb 89 | 90 | # Visual Studio profiler 91 | *.psess 92 | *.vsp 93 | *.vspx 94 | *.sap 95 | 96 | # TFS 2012 Local Workspace 97 | $tf/ 98 | 99 | # Guidance Automation Toolkit 100 | *.gpState 101 | 102 | # ReSharper is a .NET coding add-in 103 | _ReSharper*/ 104 | *.[Rr]e[Ss]harper 105 | *.DotSettings.user 106 | 107 | # JustCode is a .NET coding add-in 108 | .JustCode 109 | 110 | # TeamCity is a build add-in 111 | _TeamCity* 112 | 113 | # DotCover is a Code Coverage Tool 114 | *.dotCover 115 | 116 | # NCrunch 117 | _NCrunch_* 118 | .*crunch*.local.xml 119 | nCrunchTemp_* 120 | 121 | # MightyMoose 122 | *.mm.* 123 | AutoTest.Net/ 124 | 125 | # Web workbench (sass) 126 | .sass-cache/ 127 | 128 | # Installshield output folder 129 | [Ee]xpress/ 130 | 131 | # DocProject is a documentation generator add-in 132 | DocProject/buildhelp/ 133 | DocProject/Help/*.HxT 134 | DocProject/Help/*.HxC 135 | DocProject/Help/*.hhc 136 | DocProject/Help/*.hhk 137 | DocProject/Help/*.hhp 138 | DocProject/Help/Html2 139 | DocProject/Help/html 140 | 141 | # Click-Once directory 142 | publish/ 143 | 144 | # Publish Web Output 145 | *.[Pp]ublish.xml 146 | *.azurePubxml 147 | # TODO: Comment the next line if you want to checkin your web deploy settings 148 | # but database connection strings (with potential passwords) will be unencrypted 149 | #*.pubxml 150 | *.publishproj 151 | 152 | # Microsoft Azure Web App publish settings.
