Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

by XDK 2. July 2013 20:12

Explanation:

  • The Work item with large amount of data in the custom HTML fields fails to open after migration.
  • The error may occur for the build logs with large amount of data as well.

Workaround:

Try to modify web.config in \Program Files\Microsoft Team Foundation Server 11.0\Application Tier\Web Services to adjust the size.
The default length is 20MB, so try a larger value than that. The value below is for 50MB. Experimentation may be necessary to find the best value.

<appSettings>
<add key="maxJsonLength" value="52428800" />
</appSettings>

Installing Visual Studio 2012 and then installing Visual Studio 2010 causes unreliable results for Office Integration add-ins

by XDK 1. July 2013 11:10

Explanation

If you install Visual Studio 2012 and then install Visual Studio 2010, and then you open Office to use an Office Integration add-in, Office displays two Team ribbons. Both ribbons are unreliable and may cause worksheets to become corrupted.

Workaround

Disable the Visual Studio 2010 version of the add-in, as follows:

  1. On the menu bar in Office, choose File, Options.
  2. In the Options dialog box, select Add-Ins.
  3. In the Manage box, select COM Add-ins and then choose the Go button.
  4. In the list of add-ins, clear the check box for the Visual Studio 2010 version of the add-in and then choose the OK button. (To determine the version of an add-in, select it and then read its location at the bottom of the Options dialog box. The location for a Visual Studio 2010 add-in is "Microsoft Visual Studio 10.0".)
