Display project version in ASP.NET MVC Core application

Display project version in ASP.NET MVC Core application

To display the project version in an ASP.NET MVC Core application, you can add a middleware component that reads the version from the assembly information and adds it to the response headers. Here's an example:

  • Add a VersionMiddleware class that reads the version from the assembly information:
public class VersionMiddleware { private readonly RequestDelegate _next; public VersionMiddleware(RequestDelegate next) { _next = next; } public async Task InvokeAsync(HttpContext context) { var version = typeof(Startup).Assembly.GetName().Version.ToString(); context.Response.Headers.Add("X-Version", version); await _next(context); } }

In this example, we're adding a VersionMiddleware class that reads the version from the assembly information of the Startup class and adds it to the response headers with the key "X-Version". The middleware component then passes the request to the next component in the pipeline using the RequestDelegate object.

  • Register the VersionMiddleware in the Configure method of the Startup class:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { // ... app.UseMiddleware<VersionMiddleware>(); // ... }

In this example, we're using the UseMiddleware method to add the VersionMiddleware component to the middleware pipeline.

  • Display the version in the View or layout file:
<p>Version: @Context.Response.Headers["X-Version"]</p>

In this example, we're using the Context.Response.Headers property to access the response headers and display the version in a paragraph element.

By following these steps, you should be able to display the project version in an ASP.NET MVC Core application.

  3. "ASP.NET Core display assembly version on homepage"

    • Code:
      // In the HomeController public IActionResult Index() { ViewData["Version"] = typeof(Startup).Assembly.GetName().Version.ToString(); return View(); } 
      <!-- In the Index.cshtml --> <p>Version: @ViewData["Version"]</p>
    • Description: Passes the project version to the view data and displays it on the homepage.

  4. "ASP.NET Core show application version in footer"

    • Code:
      // In a BaseController or middleware HttpContext.Items["Version"] = typeof(Startup).Assembly.GetName().Version.ToString(); 
      <!-- In the _Layout.cshtml --> <footer> <p>Version: @HttpContext.Items["Version"]</p> </footer>
    • Description: Stores the version in HttpContext.Items and displays it in the footer of the layout.

  5. "ASP.NET Core display project version in Swagger"

    • Code:
      // In the Startup.cs, inside ConfigureServices method services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "Your API", Version = typeof(Startup).Assembly.GetName().Version.ToString() }); });
    • Description: Sets the Swagger API version using the project version in the SwaggerGen configuration.

  6. "ASP.NET Core get version from project file"

    • Code:
      string version = Assembly.GetEntryAssembly()?.GetCustomAttribute<AssemblyInformationalVersionAttribute>()?.InformationalVersion;
    • Description: Retrieves the version from the project file using AssemblyInformationalVersionAttribute.

  7. "ASP.NET Core display version on error page"

    • Code:
      // In the ErrorController ViewData["Version"] = typeof(Startup).Assembly.GetName().Version.ToString(); 
      <!-- In the Error.cshtml --> <p>Version: @ViewData["Version"]</p>
    • Description: Passes the version to the error view data and displays it on error pages.

  8. "ASP.NET Core show project version in response headers"

    • Code:
      // In a middleware context.Response.Headers.Add("X-App-Version", typeof(Startup).Assembly.GetName().Version.ToString());
    • Description: Adds the project version to the response headers for API consumers.

  9. "ASP.NET Core display version in debug information"

    • Code:
      // In the Startup.cs, inside Configure method if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); app.UseBrowserLink(); app.UseDatabaseErrorPage(); app.UseMigrationsEndPoint(); app.UseSwagger(); app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "Your API " + typeof(Startup).Assembly.GetName().Version.ToString())); }
    • Description: Includes the project version in debug information such as Swagger UI during development.

  10. "ASP.NET Core display version on about page"

    • Code:
      // In the AboutController public IActionResult Index() { ViewData["Version"] = typeof(Startup).Assembly.GetName().Version.ToString(); return View(); }
