运行Visual Studio 2019 React模板时出现错误400

Question

I created an ASP NET Core application with React template and I didnt change anything there. When I am starting it I am getting error 400 in browser. There are no errors in Output window.

Answer 1

If you copy the address which your application starts eg https://localhost:44371/ and your app loads there, then you have cache issue or some conflict.

I have cleaned my browser cache from here:

chrome://settings/clearBrowserData?search=cache

Good idea is to set a proper time period, otherwise you will erase cookies that you don't need to.

Hope this helps. It did in my case.
