How to configure Visual Studio for debugging .NET framework
Find type and member declarations, files, assemblies and GUIDs
| Search for: | Examples |
|
Full or partial type or member name.
The string needs to be a prefix, "Builder" won't find "StringBuilder", but will find "BuilderType".
Use quotes to find exact string (turns off prefix search).
|
|
| Use "assembly" prefix to search for assembly names. | |
|
Use a keyword to filter by member type:
assembly,
type,
class,
struct,
interface,
enum,
delegate,
method,
property,
event,
field,
file
|
|
| Add words separated by space to filter results to only those that contain all of the words. Can also filter by assembly name. | |
| Find .cs or .vb files. | |
| Find projects by path. | |
| Find GUIDs mentioned in string literals. |
Easy hyperlinks to files, types, members, projects/assemblies
When viewing the source code in a file, two links at the bottom provide shortcuts to the current file and the current assembly.
Click on a line number to get a hyperlink to that particular line.
| Feature | Example |
| Link to assembly | /#System.Core |
| Link to file | /#mscorlib/system/environment.cs |
| Link to line number | /#mscorlib/system/environment.cs#56 |
| Link to a type/member | /mscorlib/a.html#1f55292c3174123d (right-click the definition and choose Copy Shortcut) |
| Link to search results | /#q=Button%20PresentationFramework |
Features
| Feature | Description |
| Go To Definition | Click any identifier to go to definition. |
| Find All References | Click the symbol name in definition to find all references. Find References also shows derived types, interface implementations, base members, overriding and overridden members, class instantiations and field or property writes separately. |
| Highlight References | Click on a local variable, parameter or type parameter to highlight all references inline in source. |
 Document Outline |
In the document view, show the list of types and members in the file. |
 Project Explorer |
