With this change, platforms that don't support RC2 (currently only Android, bring-up still in progress) now try to use non-existent certificate files:

runtime/src/libraries/Common/tests/System/Net/Configuration.Certificates.cs

Lines 40 to 43 in aece157

	string contosoPfxSuffix = PlatformSupport.IsRC2Supported ? ".pfx" : ".noRC2.pfx";
	byte[] serverCertificateBytes = File.ReadAllBytes(Path.Combine(TestDataFolder, $"testservereku.contoso.com{contosoPfxSuffix}"));
	byte[] clientCertificateBytes = File.ReadAllBytes(Path.Combine(TestDataFolder, $"testclienteku.contoso.com{contosoPfxSuffix}"));
	byte[] noEKUCertificateBytes = File.ReadAllBytes(Path.Combine(TestDataFolder, $"testnoeku.contoso.com{contosoPfxSuffix}"));

Those files were added in dotnet/runtime-assets#120 and consumed in #49461. It looks like they were not included in dotnet/runtime-assets#124.

@aik-jahoda could you get those certs included in all this credentials re-passwording / suppression work? Or point us at what needs to happen here?

@elinor-fung there is a fix in runtime assets: dotnet/runtime-assets#128, I will change package version in runtime once the PR is merged and package published.
