WORKAROUND

To work around this problem, delete all files in the Temporary ASP.NET Files directory. To do this, follow these steps:

1. Click Start, click Run, type iisreset /stop, and then click OK.
2. Open the DriveLetter: WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files directory.
3. Delete all files and all folders in the directory that you located in step 2.
4. Click Start, click Run, type iisreset /start, and then click OK.

You can also work around this problem by setting the batch property of the compilation tag to false. To do this, follow these steps:

1. In the Microsoft Visual Studio 2005 project, right-click Web.config in Solution Explorer, and then click Open.
2. Locate the code that resembles the following.

   <compilation debug="false" />

3. Replace the code that you located in step 2 with the following code.

   <compilation debug="false" batch="false" />

Note If you set the value of the numRecompilesBeforeAppRestart property in the compilation tag to a high number, such as 50, you will reduce the number of times that this problem occurs. The compilation tag will resemble the following after you set the numRecompilesBeforeAppRestart property.

<compilation debug="false" numRecompilesBeforeAppRestart="50" />
