You use Microsoft Visual Studio 2008 to build a Microsoft Visual Basic project.
The Visual Basic project contains many XML comments in a single file.
The file is probably a designer-generated file for a dataset or for a Web reference.
In this scenario, you may experience the following performance issues in the IDE:
The IDE takes a long time to build the solution and to rebuild the solution.
You experience a slow response time when you press F5 to start debugging.
You experience a slow response time in the Code Editor.
You experience a slow response time in IntelliSense.
This problem occurs because of how the Visual Studio 2008 compiler processes large files that contain XML documentation.

To work around this problem, use one of the following methods.
Method 1: Disable XML comment generation
To disable XML comment generation for the project, use one of the following procedures.
Visual Studio 2008
In Solution Explorer, right-click ProjectName, and then click Properties.
On the Compile tab,click to clear the Generate XML documentation file check box.
On the File menu, click Save All.
Visual Basic 2008 Express Edition
Create a backup of the project.
In Notepad, open the .vbproj file for the project.
Locate and then delete all the <DocumentationFile> elements in the .vbproj file.
Note Typically, you will delete two elements in the .vbproj file.
Method 2: Remove the XML comments
To remove the XML comments, follow these steps for the designer-generated file:
On the Edit menu, point to Find and Replace, and then click Quick Replace.
In the Find what box, type '''.
In the Replace with box, type '', and then click Replace All.
Note You must repeat these steps if you perform one of the following actions:
You save the designer file that generated this code file.
You refresh the Web reference.
You right-click the file, and then you click Run Custom Tool.
Method 3: Create a separate project to store the file that has the XML comments
Create a new class library project to store the designer-generated files. The following procedure is an example of to do this:
Create a new class library project to store files that contain a dataset or that contain a Web reference.
In the original Visual Basic project, add a reference to the new class library project.
Use Method 1 to disable the XML documentation file.
Note You may have to add import statements to the Visual Basic code.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
