How to solve server errors in ASP. NET "/" applications, asp.net applications

When I learned how to verify the control in asp.net, I always prompted this problem when running the program: "/" server errors in the application. For example:

 

Related methods are found on the Internet:

In webconfig, find

<appSettings>    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />     <addkey="ValidationSettings:UnobtrusiveValidationMode"value="WebForms" />     </appSettings> 

Then delete<Addkey = "ValidationSettings: UnobtrusiveValidationMode" value = "WebForms"/>You can.

However, when you view the content in the configuration file, you find that there is no such content at all, and you cannot add all the content. I don't want to think about it anymore. I will put it aside for the moment.

However, I have been talking about this issue for a long time. Then I carefully read the content added to the configuration file and found that the second key is for the Validation control and the final attribute is set to "WebForms ", I have seen similar problems on the Internet before, so I willSet the value attribute to "None ",Then run the task again.

The added content is:

<Add key = "ValidationSettings: UnobtrusiveValidationMode" value = "None"/>

We hope that the solution provided in this Article can help you solve server errors in the "/" application.
