coverlet.collector v3.1.0 causes fatal package downgrade of Microsoft.Extensions.DependencyInjection

[TonyTroeff]

In some of my tests my team needs to start an instance of one of our services. This is a part of the code:

var hostBuilder = CreateHostBuilder(args);
var host = hostBuilder.Build();
await host.ExecuteStartupTasksAsync();

await host.RunAsync();

Unfortunatelly, after publishing the tests project the reference to Microsoft.EXtensions.DependencyInjection is downgraded to 2.2.0 and we receive the following exception upon tests execution:

Error Message:
   System.MissingMethodException : Method not found: 'Void Microsoft.Extensions.DependencyInjection.ServiceProviderOptions.set_ValidateOnBuild(Boolean)'.
  Stack Trace:
     at Microsoft.Extensions.Hosting.Host.<>c.<CreateDefaultBuilder>b__1_3(HostBuilderContext context, ServiceProviderOptions options)
   at Microsoft.Extensions.Hosting.HostingHostBuilderExtensions.<>c__DisplayClass3_0.<UseDefaultServiceProvider>b__0(HostBuilderContext context)
   at Microsoft.Extensions.Hosting.Internal.ServiceFactoryAdapter`1.CreateBuilder(IServiceCollection services)
   at Microsoft.Extensions.Hosting.HostBuilder.CreateServiceProvider()
   at Microsoft.Extensions.Hosting.HostBuilder.Build()

This property ValidateOnBuild is added after Microsoft.Extensions.DependencyInjection version 3.0.0 so it really could not be found.

I would be very interested to understand why coverlet should reference this package and how could we potentially fix our issue without removing coverlet as this is something we would not like to do.

This is mostly a guess, but it may be similar to the issue with Newtonsoft.Json during publish that was fixed by #1243, so maybe that PR will also fix this case. It's not released yet, but should be in the nightly build if you want to give it a try:

@petli is right, can you try the nightly build and let us know if it's solved?
So we can also do a release asap.

Solved into shipped 3.1.1
