I have just upgraded from .NET SDK 10.0.202 to 10.0.203 and upon compiling an application, have been treated to the following error:

SDKError

The details are as follows:

An issue was encountered verifying workloads. For more information, run "dotnet workload update".

The problem, needless to say, is the workloads.

We fix them by running the dotnet workload update command:

dotnet workload update

If you are on macOS or Linux, you must run them as root:

sudo dotnet workload update

You should get the following output:

Successfully updated workload(s): .

TLDR

Fix the “An issue was encountered verifying workloads” error by updating your workloads.

Happy hacking!
