.NET MAUI workload restore error Failed to run MSBuild Target _GetRequiredWorkloads

Question

**When I create and Build a .NET MAUI application (.NET 6), I get the following errors. How can I solve them? Visual Studio 2022 version 17.4.2 Is this problem related to my country's internet? (From Iran) Is the problem with certain individual components that I have not installed? Errors

Build

Answer 1

I had the exact same errors with the "hello world", "click me" app that is the default. It worked for weeks then suddenly it would no longer compile. Got the same errors.

After a few weeks of looking, this finally resolved it for me:

In the Developer Command Prompt I ran:

dotnet workload install maui

(run this with sudo if you get not enough permissions error)

This ran for quite a while.

After it completed I exited out of visual studio, restarted, reloaded the solution, but it still failed. I gave it time to do all the stuff it seemed to be doing.

I exited out of visual studio more time, relaunched and I am now compiling. (I fear it will stop again at some point).
