System.IO.IOException: Failed to bind to address https://127.0.0.1:5001: address already in use.

In this post I will show you how to solve above problem. To solve this problem there are multiple ways in VS Code. some of them are...
Before that previously I had shown you

• How to Install Linux on Raspberry Pi 3
• How to Install .Net Core 3.1 on Raspberry Pi 3
• Jquery DataTable Custom Excel Export
• Jquery DataTable Custom PDF Export
• Jquery DataTable Custom PDF Export with New Column
• Jquery DataTable Custom PDF Export with logo
• The entity type '' requires a primary key to be defined.
• Unable to configure HTTPS endpoint. No server certificate was specified

Solution:

Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date.

In this post I will show you how to solved the Issue. Here I am using VS Code.
Previously I had shown

• How to Install .Net Core 3.1 on Raspberry Pi 3
• Jquery DataTable Custom Excel Export
• Jquery DataTable Custom PDF Export
• Jquery DataTable Custom PDF Export with New Column
• Jquery DataTable Custom PDF Export with logo
• The entity type '' requires a primary key to be defined.

To solve this problem I had generated certificates as described in the error message as shown below.
    To generate a developer certificate run 'dotnet dev-certs https'.
    To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'.
    But no use.

Don't worry there is a solution.

Steps for solution:

The entity type '' requires a primary key to be defined. If you intended to use a keyless entity type call 'HasNoKey()'.

As the title says The entity type '' requires a primary key to be defined. If you intended to use a keyless entity type call 'HasNoKey()'.
