 .SYNOPSIS
-    Generates a filtered .slnx solution file that only includes test projects supporting a given target framework.
+    Generates a filtered .slnx solution file by removing projects that don't match the specified criteria.
 
 .DESCRIPTION
-    Parses a .slnx solution file and queries each test project's TargetFrameworks using MSBuild.
-    Removes test projects that don't support the specified target framework, writes the result
-    to a temporary or specified output path, and prints the output path.
-
-    This is useful for running `dotnet test --solution` with MTP (Microsoft Testing Platform),
-    which requires all test projects in the solution to support the requested target framework.
+    Parses a .slnx solution file and applies one or more filters:
+    - Removes projects that don't support the specified target framework (via MSBuild query).
+    - Optionally removes all sample projects (under samples/).
+    - Optionally filters test projects by name pattern (e.g., only *UnitTests*).
+    Writes the filtered solution to the specified output path and prints the path.
 
 .PARAMETER Solution
     Path to the source .slnx solution file.
