Blazor Boilerplate

Blazor is a web framework designed to run in the browser on a WebAssembly-based .NET runtime. Blazor Boilerplate aka Blazor Starter Template is a SPA admin template that is able to run both WebAssembly (Core-Hosted) and Server-Side Blazor with a .NET 5.0 Server. Default mode for BB is Server Side. To switch to Webassembly log in as Admin and go to settings. Read more here

Blazor Web Developer Opportunity

Enkode, the originator of Blazor Boilerplate is actively looking for an individual to help write code that is built off of the Blazor Boilerplate platform. It is a part-time position, salary based off of experience. I am willing to help mentor beginners. Interested persons email:

  • Fluxor - Branched from version 0.6.0 with an example with Blazor Fluxor *Note: not maintained

Build Status Live Demo GitHub Stars GitHub Issues MIT Donate Gitter


  • This repository is community driven. It is not and never will be controlled by a corporation. It's success is dependent on people using it, reviewing it, offering suggestions and most importantly contributing. Please join the gitter discussion
  • To create a boilerplate with Blazor / Razor components that includes the most common functionality to start a real world application quickly.
  • Avoid many external components & libraries which can make it difficult to maintain, update, track down code, learn code and issues.
  • Minimal Javascript. Currently only using them for MatBlazor / Material Design. We may use components with JS in them but so far no Javascript has been written specifically for anything in the repository.

Complete all Blazor dependencies.

  • The latest .Net 5.0 SDK
  • Install the Latest Visual Studio 2019 with the ASP.NET and web development workload selected.
  • Entity Framework Core on the command-line tools: dotnet tool install --global dotnet-ef

How to run

  1. Install the latest Visual Studio 2019 (v16.8 at least)
  2. Clone or download.
  3. Review / Update appsettings.json - DefaultConnection.
  4. Open the solution in Visual Studio and press F5.
  5. To view the API using Swagger UI, Run the solution and go to: http://localhost:53414/swagger/index.html. Live example:

Publish on IIS - What works for me on my Windows Server 2016 & SQL Server 2014 (Enkodellc)

  1. Publish BlazorBoilerplate.Server project to your IIS website folder.

  2. Install your SSL. Make sure your SSL is in the WebHosting Certificate Store, and in Linux My Certificate Store.

    • A free certificate from Let's Encrypt will work.
    • For steps 2 & 3 the utility win-acme installs the certificate on your server, performs renewal and configure your IIS Website Bindings to have https binding with the SSL certificate set and Port 443 for default.
  3. Configure your IIS Website Bindings to have https binding with the SSL certificate set and Port 443 for default. Enable WebSockets for SignalR.

  4. Configure / create appsettings.production.config. Set Connection String. If you are using Sql Server then make sure your connection string contains MultipleActiveResultSets=true, Set Thumbprint / SSL. Thumbprint example: 143fbd7bc36e78b1bcf9a53c13336eaebe33353a

  5. Login with either the user [user | user123] or admin [admin | admin123] default accounts.

Thanks To


Please star, watch and fork! We'd greatly appreciate any contribution you make. I am very open to updates and features, though most feature requests will be depending on how much community support exists.

Disclaimer / About the Author

I (Enkodellc) started this repository as I was frustrated with the examples out there that people were charging money for and were in my opinion incomplete or closed source. I paid for 4-5 of these solutions with an Angular front-end / .Net Core back-end and none of them were what I was looking for. This is my attempt to create something that developers can start a Blazor project with several great features to build from. I have a lot of experience with ASP.Net webforms an new to .NET Core and Blazor. This code is not meant to be perfect or follow every best practice. It though is my ambition to learn and get feedback on what best practices can be implemented. I will be migrating a Webforms app to Blazor so this is my opportunity to learn, share, grow, and get feedback on what hopefully will be a great Blazor Starter Kit.

I have taken small solutions from other repositories and will do my best to recognize those contributions. I am very open to ideas and suggestions. I am not a great developer, but I try. So please take this into consideration when using this repository. If you wish to hire me for consulting or as a contractor please reach out via email or I have taken well over 1,000 hours to create, maintain, and answer questions. Please donate to support my efforts.

Problem Solving Tips

  • If you are having issues wih authentication or any other strange behavior try using Incognito mode / different browser.
  • Make sure you have all pre-requisites installed.
  • Keep It Simple Stupid: If you are running into issues with SQL / connection string. First CHECK both appsettings.json (appsettings.production.json for production) and (appsettings.development.json for development).
  • Test out with SQLlite / file db. Then test out with a known good connection string.
  • Go back to the Origin: BlazorBoilerplate was built off of BlazorWithIdentity so first step is to run this and try and publish. The reasoning is that this is a very lean project to reduce the amount of code and resources requiring debugging.
  • If still failing get on Gitter BlazorBoilerplate for Blazor Boilerplate or Gitter aspnet/Blazor.
  • Debugging is very limited on WebAssembly / Client-side Blazor. Use Debug_SSB for debugging the UI. Just be aware of browser caching issues when switching modes. The server side of the project can easily be debugged, just not there yet on the client-side code.
  • If you are getting compiler errors try and close VS delete your .vs directory in the solution folder. If that doesn't work delete the solution and redownload the repo.

Postgres Support

*Note this might be out of date.. Delete Existing Migrations in the BlazorBoilerplate.Server/Migrations Folder and then create your own migrations:
-dotnet ef --startup-project ..\BlazerBoilerplate.Server migrations add InitialApplicationDbMigration --context ApplicationDbContext -o Migrations\ApplicationDb
-dotnet ef --startup-project ..\BlazorBoilerplate.Server\ migrations add InitialConfigurationDbMigration --context ConfigurationDbContext -o Migrations\ConfigurationDb
-dotnet ef --startup-project ..\BlazorBoilerplate.Server\ migrations add PersistedGrantDbContext --context PersistedGrantDbContext -o Migrations\PersistedGrantDb

Docker Support

  • Prerequisite: Install Docker Desktop
  • Include / Reload docker-compose project in solution.
  • Do Docker stuff - I don't have much experience with Docker.
  • In the command line go to the Utils folder and run "docker-compose build". Once complete run "docker-compose up"
  • The following will happen in the browser with ASPNETCORE_ENVIRONMENT=Development:
  • Connecting via localhost in chrome or firefox: You will get a console error: "Cannot assign requested address (localhost:port)" - because the js client is trying to connect to your local machine rather than the docker container. Login will not work.
  • Connecting over external ip address/dns: Login will work, but you will get a console error in the following scenarios:
  • In chrome over http: Cannot read property 'register' of undefined. Login works. After login: There is no additional error.
  • In chrome over https: 1) An SSL certificate error occurred when fetching the script; 2) DOMException: Failed to register a ServiceWorker for scope ('https://x.x.x.x:port/') with script ('https://x.x.x.x:port/service-worker.js'); Login works. After login: There is no additional error.
  • In firefox over http: 1) navigator.serviceWorker is undefined. Login works. After login: WebSocket is not in the OPEN state
  • In firefox over https: 1) No errors. Login works. After login: WebSocket is not in the OPEN state.
  • In ASPNETCORE_ENVIRONMENT=Production: http will redirect to https. If you are using a self signed/invalid ssl certificate the following will occur:
  • In chrome or firefox over https: Same as above except login will fail. After login attempt: There was an unhandled exception on the current circuit, so this circuit will be terminated.
  • Note: In Production, if the httpClientHandler server certificate validation returns false (caused by a self signed/invalid ssl certificate) then the login will fail. In Development, overriding the certificate validation via ServerCertificateCustomValidationCallback = () => { return true; } prevents the ssl cert validation from failing which causes the login to succeed.

Azure Support
