Any way to create a JWT token with key size 512? and changing default minimum size requirement of AsymmetricSignatureProvider

Question

I am currently getting following error:

IDX10630: The \'Microsoft.IdentityModel.Tokens.RsaSecurityKey, KeyId: \'...\', InternalId: \'5a946596-9fe6-4c91-8c

Following is the solution i have used

var mainclass = typeof(AsymmetricSignatureProvider)
                       .GetField(nameof(AsymmetricSignatureProvider.DefaultMinimumAsymmetricKeySizeInBitsForSigningMap), BindingFlags.Public | BindingFlags.Static);
                var field = mainclass.GetValue(null) as Dictionary<string, int>;
                if (field != null)
                {
                    field["RS256"] = 512;

                }

                var mainclass2 = typeof(AsymmetricSignatureProvider).GetField(nameof(AsymmetricSignatureProvider.DefaultMinimumAsymmetricKeySizeInBitsForVerifyingMap), BindingFlags.Public | BindingFlags.Static);
                var field2 = mainclass2.GetValue(null) as Dictionary<string, int>;
                if (field2 != null)
                {
                    field2["RS256"] = 512;
                }
