Additional info

I had issues related to signing certificate in the certificate store when I tried running it with the debugger even before I edited any code. I deleted:

<PropertyGroup>
  <ManifestCertificateThumbprint>F0BB6B4AB81DCB530A46721FAE58938516286746</ManifestCertificateThumbprint>
</PropertyGroup>
<PropertyGroup>
    <ManifestKeyFile>BorderlessMinecraft_TemporaryKey.pfx</ManifestKeyFile>
</PropertyGroup>
<PropertyGroup>
    <GenerateManifests>true</GenerateManifests>
</PropertyGroup>
<PropertyGroup>
    <SignManifests>true</SignManifests>
</PropertyGroup>

However, I left it out of this pull request as I believe the error occurred at the fault of myself.
