The book takes you through an introduction to the microservices architectural style. Next, you'll learn important practical aspects of developing microservices from simple core concepts to more sophisticated. Throughout the book, you'll see many code examples implementing it with lightweight .NET technologies—most prominently Nancy. By the end, you'll be able to quickly and easily build reliable and operations-friendly microservices using Nancy, OWIN and other open technologies. ## Branches From time to time I will update the code use newer versions of libraries as well as .NET Core. I will keep each such update in a branch. The brances in the repository are: * `master`: The code as it appears in the book * `2017-05`: Everything updated to use `csproj` files instead of `project.json` files, so it's compatible with Visual Studio 2017 and newer `dotnet` command line versions. Furhtermore everything is updated to .NET Core 1.1 and Nancy 2.0.0-clinteastwood. ================================================ FILE: src/Chapter01/HelloMicroservices/.gitignore ================================================ ## Ignore Visual Studio temporary files, build results, and ## files generated by popular Visual Studio add-ons. # User-specific files *.suo *.user *.userosscache *.sln.docstates # User-specific files (MonoDevelop/Xamarin Studio) *.userprefs # Build results [Dd]ebug/ [Dd]ebugPublic/ [Rr]elease/ [Rr]eleases/ x64/ x86/ build/ bld/ [Bb]in/ [Oo]bj/ # Visual Studio 2015 cache/options directory .vs/ # Uncomment if you have tasks that create the project's static files in wwwroot #wwwroot/ # MSTest test Results [Tt]est[Rr]esult*/ [Bb]uild[Ll]og.* # NUNIT *.VisualState.xml TestResult.xml # Build Results of an ATL Project [Dd]ebugPS/ [Rr]eleasePS/ dlldata.c # DNX project.lock.json artifacts/ *_i.c *_p.c *_i.h *.ilk *.meta *.obj *.pch *.pdb *.pgc *.pgd *.rsp *.sbr *.tlb *.tli *.tlh *.tmp *.tmp_proj *.log *.vspscc *.vssscc .builds *.pidb *.svclog *.scc # Chutzpah Test files _Chutzpah* # Visual C++ cache files ipch/ *.aps *.ncb *.opendb *.opensdf *.sdf *.cachefile # Visual Studio profiler *.psess *.vsp *.vspx *.sap # TFS 2012 Local Workspace $tf/ # Guidance Automation Toolkit *.gpState # ReSharper is a .NET coding add-in _ReSharper*/ *.[Rr]e[Ss]harper *.DotSettings.user # JustCode is a .NET coding add-in .JustCode # TeamCity is a build add-in _TeamCity* # DotCover is a Code Coverage Tool *.dotCover # NCrunch _NCrunch_* .*crunch*.local.xml nCrunchTemp_* # MightyMoose *.mm.* AutoTest.Net/ # Web workbench (sass) .sass-cache/ # Installshield output folder [Ee]xpress/ # DocProject is a documentation generator add-in DocProject/buildhelp/ DocProject/Help/*.HxT DocProject/Help/*.HxC DocProject/Help/*.hhc DocProject/Help/*.hhk DocProject/Help/*.hhp DocProject/Help/Html2 DocProject/Help/html # Click-Once directory publish/ # Publish Web Output *.[Pp]ublish.xml *.azurePubxml # TODO: Comment the next line if you want to checkin your web deploy settings # but database connection strings (with potential passwords) will be unencrypted *.pubxml *.publishproj # NuGet Packages *.nupkg # The packages folder can be ignored because of Package Restore **/packages/* # except build/, which is used as an MSBuild target. !**/packages/build/ # Uncomment if necessary however generally it will be regenerated when needed #!**/packages/repositories.config # Microsoft Azure Build Output csx/ *.build.csdef # Microsoft Azure Emulator ecf/ rcf/ # Microsoft Azure ApplicationInsights config file ApplicationInsights.config # Windows Store app package directory AppPackages/ BundleArtifacts/ # Visual Studio cache files # files ending in .cache can be ignored *.[Cc]ache # but keep track of directories ending in .cache !*.[Cc]ache/ # Others ClientBin/ ~$* *~ *.dbmdl *.dbproj.schemaview *.pfx *.publishsettings node_modules/ orleans.codegen.cs # RIA/Silverlight projects Generated_Code/ # Backup & report files from converting an old project file # to a newer Visual Studio version.
