+======= what is the actual publish command =======
+specify output folder. I don't know what all the other bullshit it insists on dumping in the folder is.
+<code>
+dotnet publish -c Release -o ../publish
+</code>
+also you can't not get ''appsettings.Development.json'' to show up in release. your only option is to delete it manually.
+======= why is asp.net not accepting my frombody thing? =======
+microsoft replaced the working json parser with one that doesn't. https://devblogs.microsoft.com/dotnet/try-the-new-system-text-json-apis/
+fix:
+  - ''dotnet add package Microsoft.AspNetCore.Mvc.NewtonsoftJson --version [compatible version]''
+  - go find where services are being added; ''services.AddControllers().AddNewtonsoftJson();''. (hint: Builder.Services?)
+======= which is a field, which is a property? =======
+<code csharp>
+public class MyClass
+{
+    // this is a field.  It is private to your class and stores the actual data.
+    private string _myField;
+    // this is a property. When accessed it uses the underlying field,
+    // but only exposes the contract, which will not be affected by the underlying field
+    public string MyProperty
+    {
+        get
+        {
+            return _myField;
+        }
+        set
+        {
+            _myField = value;
+        }
+    }
+    // This is an AutoProperty (C# 3.0 and higher) - which is a shorthand syntax
+    // used to generate a private field for you
+    public int AnotherProperty { get; set; }
+}
