Error when changing an applications Target Framework from 2.0 to 4.0

I've had a problem with Crystal Reports when changing an applications Target Framework from 2.0 to 4.0 

Error:
Could not load file or assembly 'file:///C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.

Resolution:
Add the following to app.config:

<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime Version="v4.0" sku=".NETFramework, Version=v4.0" />
startup>

System: VS 2010, Crystal Reports 13, Windows 7 x64 

Make Visual Studio 2010 use more than 2GB of RAM

Tested on Windows 7 Ultimate x64:

1. Make a backup of 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devaenv.exe'
2. Add 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin' without quotes to PATH variable
3. Open cmd under: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE
4. Run in cmd: 'editbin /LARGEADDRESSAWARE devenv.exe' without quotes
5. Restart

Visual Studio 2008 Windows 7 x64 doesn't break on throw new Exception

I thought so too, but after a little search I found that under Visuals Studio Debug-Exceptions menu the "thrown" checkbox under Common language runtime exceptions wasn't checked. To solve the problem, just check "thrown" under CLRE.
