+
+## Type specification and Loading
+
+A significant change was made to the type specification language.  Instead of having to type `|System.Collections.Generic.Dictionary``2[System.String, System.Collections.List``1[System.Int64]]|`, 
+one can now declare type aliases and also use special type names such as `int` as generic type arguments.
+By declaring type aliases
+
+```clojure
+(alias-type Dictionary |System.Collections.Generic.Dictionary`2|)
+(alias-type List |System.Collections.Generic.List`1|)
+(alias-type IntList |List[int]|)
+```
+
+one can refer to types in this way:
+
+```clojure
+|Dictionary[String, List<long>]|
+|Dictionary[String, IntList]|
+```
+
+and create expressions such as
+
+```clojure
+(def my-list (IntList/new))
+(IntList/.Add my-list 42)
+```
+
+In addition, changes were made to improve discovery of assemblies that should be checked and automatically loaded when looking up types.
+The `DependencyContext`	class is used to find the entry assembly's dependencies.  We also discover assemblies that are part of the shared
+.NET runtime via `AppContext.GetData("TRUSTED_PLATFORM_ASSEMBLIES")`. 
+
+Note that the `AppContext.GetData` is not available on Framework 4.6.2.  A build for Framework 4.8.1 was added -- if you want to take advantage of the improved assembly discovery under .NET Framework, you will have to move to that version.
+
+Details are available in the blog post [Typename syntax and resolution in ClojureCLR](https://dmiller.github.io/clojure-clr-next/general/2025/09/21/typename-syntax-and-resolution.html).
