'IConfiguration' does not contain a definition for 'GetSection'

I am trying to add authentication to a web api with .Net 5 but I get the error above in the method I am creating the token.

private string CreateToken(User user)
    {
        List<Claim> claims = new List<Claim>
        {
            new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
            new Claim(ClaimTypes.Name, user.Username)
        };

        // The underlined error is on the line below on the GetSection method.
        SymmetricSecurityKey key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration.GetSection("AppSettings:Token").Value));

        SigningCredentials creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha512Signature);

        SecurityTokenDescriptor tokenDescriptor = new SecurityTokenDescriptor
        {
            Subject = new ClaimsIdentity(claims),
            Expires = DateTime.Now.AddDays(1),
            SigningCredentials = creds
        };

        JwtSecurityTokenHandler tokenHandler = new JwtSecurityTokenHandler();
        SecurityToken token = tokenHandler.CreateToken(tokenDescriptor);

        return tokenHandler.WriteToken(token);
    }

I have done this in a previous project before and it worked fine. Added the same packages in the same version of .Net.

Not sure what else could be causing this.

Thanks.

The IConfiguration interface should come from the Microsoft.Extensions.Configuration library.

In this case the IConfiguration interface was a definition from AutoMapper.Configuration.

Perhaps the Microsoft.Extensions.Options.ConfigurationExtensions library also may be required because of IOptions<>.
