Can't open solution in VS 2019

Hi there,

I download the last version of NC (nopCommerce_4.30_Source.zip). Unzip to an folder and try to open the "NopCommerce.sln" with VS 2019. On my Windows 10 desktop VS 2019 Version 16.5.0 and the .net Framework 4.8.04... are installed, also the  Core SDK and runtime. MS SQL >2012.

The message of VS is:

Thank you, dear Yidna,

Today VS offered me an update. I installed it and tried to download the solution. See there, now it was opened.

I hope, now everything else works as well!

Kind regards,
Walter
