I'm working on a project and hit a roadblock. I'm trying to implement I'm integrating two systems and I'm not sure how to approach While developing a suite of microservices in ASP.NET Core, we decided to integrate Swagger UI for better API documentation and testing. However, testing on different browsers reveals inconsistent rendering issues, especially in Internet Explorer and Safari. The Swagger UI looks perfect in Chrome and Firefox, but some elements are misaligned or completely missing in other browsers. I’ve tried multiple approaches to resolve this, including: 1. Ensuring that all CSS and JavaScript files are loading correctly and not being blocked due to CORS policy. 2. Updating the Swagger dependencies to the latest versions by running `dotnet add package Swashbuckle.AspNetCore --version 6.3.0`, as per the documentation recommendations. 3. Validating the API responses in the browser’s developer tools to ensure that they return the expected data format consistently across browsers. Despite these attempts, the specific issue persists. Here’s a snippet of how I’ve configured Swagger in the `Startup.cs`: ```csharp public void ConfigureServices(IServiceCollection services) { services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" }); }); } public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseSwagger(); app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1"); c.RoutePrefix = string.Empty; // Set Swagger UI at the app's root }); } ``` I’ve also considered polyfills or shims to address JavaScript compatibility issues but haven’t settled on one. It would be helpful to know what specific steps can be taken to ensure that Swagger UI works seamlessly across all major browsers, particularly focusing on older versions of IE or differences in rendering engines. Any insights or best practices to make this work smoothly would be greatly appreciated! Thanks for any help you can provide! I appreciate any insights! This is part of a larger REST API I'm building. Thanks in advance! I've been using C# for about a year now. Thanks in advance!
