Issues with swagger after migrating to .NET Core 3.0
There is a discussion on the aspnet/AspNetCore github repo discussing this: Restore MvcJsonOptions to ASP.NET Core 3.0 as a type forward?
It suggests the issue was resolved.
I'd suggest ensuring you have the latest Swashbuckle.AspnetCore package installed: https://www.nuget.org/packages/Swashbuckle.AspNetCore/
In the offical asp.net core docs, it states:
Install-Package Swashbuckle.AspNetCore -Version 5.0.0-rc2
So I'd suggest you need to install a pre-release version, at the time of writing only 4.X is stable and 5.0.0-rc3 is the latest.

After migrating to .NET Core 3.0. I'm having issues configuring swagger.
Following is my configuration.
public void ConfigureServices(IServiceCollection services) { services.AddMvc().SetCompatibilityVersion(Microsoft.AspNetCore.Mvc.CompatibilityVersion.Version_3_0).AddNewtonsoftJson(); services.AddSwaggerGen(setup => { setup.SwaggerDoc( "v1", new Info { Title = "Docker", Version = "v1" }); }); } public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { Configuration.SwaggerOptions swaggerOptions = new Configuration.SwaggerOptions(); _configuration.GetSection("SwaggerOptions").Bind(swaggerOptions); app.UseSwagger(options => { options.RouteTemplate = swaggerOptions.JsonRoot; }); app.UseSwaggerUI(options => { options.SwaggerEndpoint(swaggerOptions.UiEndpoint, swaggerOptions.ApiDescription); }); }
Following is the exception
TypeLoadException: Could not load type 'Microsoft.AspNetCore.Mvc.MvcJsonOptions' from assembly 'Microsoft.AspNetCore.Mvc.Formatters.Json
Is there a solution for this ?
