SearchPatterns Property

Search patterns to use when looking for assemblies for the PartsCatalog.

Syntax

Visual Basic
C#

'Declaration
 
Public Shared Property SearchPatterns As List(Of String)

'Usage
 
Dim value As List(Of String)
 
CompositionHost.SearchPatterns = value
 
value = CompositionHost.SearchPatterns

public static List<string> SearchPatterns {get; set;}

Remarks

For ASP.NET and Silverlight applications the default is "*.dll"; for other applications the default is "*.dll" and "*.exe".

You may add and remove patterns from the list to suit your needs. You may supply a Regex pattern or a simple wildcard pattern. If you supply a simple pattern it will be converted to a Regex pattern. The conversion escapes the "." (dot) character, and changes "*" (wildcard) to ".*".

Use the SearchPatterns and IgnorePatterns to improve the startup time of your application. The only assemblies which must be probed for discovery purposes are those containing your entity models, extensible components and known types. If many unnecessary assemblies are probed the startup time of your application will suffer. However, if assemblies which should be probed are not, your application will not work correctly.

SearchPatterns are applied before IgnorePatterns.

Example

<code lang="C#">
  // At application startup
  CompositionHost.SearchPatterns.Clear();
  CompositionHost.SearchPatterns.Add("DomainModel.dll");  //  Add whatever assemblies you need probed
