After installing ASP.NET Core 2018.2.516 errors on compile?

[Rob Ainscough]

I'm getting the following errors every time I start a Compile on my Web Solution (SL5 application with some standard ASP.NET)

"Operation Failed"

An exception was thrown while initializing part of "NuGet.PackageManagement.VisualStudio.VSSolutionManager". GetFullVsVersionString must be called on the UI thread.

 

I have NO idea what this error message means and it ONLY started to happen AFTER I installed ASP.NET Core 2018.2.516 which is actually being refrenced in my Web Solution so I don't understand why this installation would cause this problem??

Tried a new project (actually trying to get the JS and CSS stuff!) and it compiled but immediately caused IIS 502.5 error.

Suspect this product isn't the focus of development in what must be a hectic schedule.

All seems a bit clunky!

Hello Chairmaker,

We are not aware of such issues, related to our latest official release. This is why, I would like to ask you to provide us with the mentioned standalone project, where the last reported problem occurred. Hence, we will be able to locally test and pin down the reason for the problem.

Hi Nencho,

I believe this has now been fixed by Telerik - it was a template error  https://www.telerik.com/forums/net-2-1-template-does-not-work 

Always a bit disconcerting when you create a new project from a template, hit F5 and it crashes! 

No big deal. Looks like it's all solved now.

Thank you,

Hello Peter,

Indeed the issue was caused by the official release of Core 2.1. However, we have fixed it and everything should work properly now.

Let me know, should you have any other questions.
