Can you let me know what version of Visual Studio you have? Help -> About

[ellix4u]

I use visual studio 2017

[jamesmontemagno]

I have 15.6.4, the latest stable, which has a lot of fixes in it and it is building good for me here. I would highly recommend upgrading to the latest VS 2017 version for sure ;)

I am going to bump the Xamarin.Build.Download to 0.4.9, however some other said that 0.4.5 may work for older versions.

[ellix4u]

Well, i can't update now but the solution should be able to work with at least any vs2015-2017. I get a lot of error(as below) after i downgraded to Xamarin.Build.Download to 0.4.5.

[jamesmontemagno]

I optimize all solutions for the latest version of VS 2017 which is what I have currently. I can't go backwards in VS world to test really at all. I would say try 0.4.9 and see what it says. Do a full clean and re-compile. I can't reproduce locally.

[ellix4u]

OK. But i have tried 0.4.9 (check the first message and picture).

[jamesmontemagno]

So, I have to assume it was an issue that they fixed with newer versions of VS 2017.

I am not sure why that even comes up seeing progaurd isn't even on in the project properties. I tried it on another machine and seemed to be working for me.

Could you try one more thing just to see and install 0.4.4?

Another question is if you had upgraded any other libraries at all?
