ASP.NET Web API fails on startup with net::ERR_HTTP2_PROTOCOL_ERROR

[evan-cx]

Describe the Bug

We added Mvp.Xml as a dependency in our ASP.NET Web API, which caused a net::ERR_HTTP2_PROTOCOL_ERROR on startup when application was started on a server without internet access. When we removed the package from the application dependencies, the application started without issue. My suspicion is that the Mvp.SponsorLink package is calling home even though the documentation says it won't. Another thought is that the System.Net.Http.WinHttpHandler package, which SponsorLink requires, is checking to see if HTTP/2 is supported on the host.

Steps to Reproduce

Run a ASP.NET application in IIS 10

Expected Behavior

Application startup is successful

Exception with Stack Trace

Client did not give us the full stack trace.

Version Info

v3.0.0

Additional Info

We don't run into the same issues when we run the app on a server with internet access.
