It will attempt to connect to the broker based upon the configuration in the `appsettings.json` file. -------------------------------------------------------------------------------- /SampleService.sln: -------------------------------------------------------------------------------- 1 |  2 | Microsoft Visual Studio Solution File, Format Version 12.00 3 | Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "SampleService", "SampleService\SampleService.csproj", "{54FC15AF-8BA2-48F2-9B05-62FDC4204985}" 4 | EndProject 5 | Global 6 | GlobalSection(SolutionConfigurationPlatforms) = preSolution 7 | Debug|Any CPU = Debug|Any CPU 8 | Release|Any CPU = Release|Any CPU 9 | EndGlobalSection 10 | GlobalSection(ProjectConfigurationPlatforms) = postSolution 11 | {54FC15AF-8BA2-48F2-9B05-62FDC4204985}.Debug|Any CPU.ActiveCfg = Debug|Any CPU 12 | {54FC15AF-8BA2-48F2-9B05-62FDC4204985}.Debug|Any CPU.Build.0 = Debug|Any CPU 13 | {54FC15AF-8BA2-48F2-9B05-62FDC4204985}.Release|Any CPU.ActiveCfg = Release|Any CPU 14 | {54FC15AF-8BA2-48F2-9B05-62FDC4204985}.Release|Any CPU.Build.0 = Release|Any CPU 15 | EndGlobalSection 16 | EndGlobal 17 | -------------------------------------------------------------------------------- /SampleService/AppConfig.cs: -------------------------------------------------------------------------------- 1 | namespace SampleService 2 | { 3 | public class AppConfig 4 | { 5 | public string Host { get;
