Vb.net – Opening Crystal Report Viewer in VB.NET

This MSDN thread explains how to fix it.

To summarize:

• Either disable incremental linking, by going to

  Project Properties 
     -> Configuration Properties 
         -> Linker (General) 
            -> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"
  

• or install VS2010 SP1.

Edits (@CraigRinger): Note that installing VS 2010 SP1 will remove the 64-bit compilers. You need to install the VS 2010 SP1 compiler pack to get them back.

This affects Microsoft Windows SDK 7.1 for Windows 7 and .NET 4.0 as well as Visual Studio 2010.

Here is how I solved the "slow symbol loading" problem in Visual Studio 2012:

• Go to Tools -> Options -> Debugging -> General

• CHECK the checkmark next to "Enable Just My Code".

• Go to Tools -> Options -> Debugging -> Symbols

• Click on the "..." button and create/select a new folder somewhere on your local computer to store cached symbols. I named mine "Symbol caching" and put it in Documents -> Visual Studio 2012.

• Click on "Load all symbols" and wait for the symbols to be downloaded from Microsoft's servers, which may take a while. Note that Load all symbols button is only available while debugging.

• UNCHECK the checkmark next to "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.

• Click "OK".

From now on, symbol loading should be much faster.

Note that if you make any changes/downloads to Microsoft assemblies, you may need to go back into the Symbols dialog box and "Load all symbols" again.
