When checking if the provided assembly is the Entry Point Assembly, we
previously just checked if the AssemblyNames were equal, but it turns
out AssemblyName doesn't implement Equals, so it was using Reference
Equality, which fails. This change uses Assembly.Equals, which has an
Equals implementation that works.
Also adds some tests to ensure it's working.
This unblocks scenarios where the EntityFramework `dotnet-ef` command
was trying to read DependencyContext.Default but receiving a null
reference.
- ProjectModel uses AssemblyLoadContext which is only available in netstandard1.5. Moving ProjectModel and all its dependencies up to netstandard1.5.
- Work around our dependencies still being on old CoreFX builds by hoisting System.Runtime.Serialization.Primitives, System.Private.DataContractSerialization, System.Linq.Expressions, and System.Xml.XmlSerializer references to the current version.
Update .exe's project.json Target Framework from dnxcore50 to netstandardapp1.5.
Update .dll's project.json Target Framework from dnxcore50 to netstandard1.3.
Adding workaround for DataContractSerialization to src\dotnet\project.json to fix crossgen issue.
Build 23901 has a dependency issue that doesn't allow the runtime.any.System.Private.DataContractSerialization
package to be restored. When we move to a new build of CoreFX we should take this workaround out.
