ClickOnce deployed Lightswitch application (Out-Of-Browser) white screen

Question

I have a LightSwitch application that is deployed Out-Of-Browser using ClickOnce.

When a user installs and starts the application, a window opens and I can see Silverlight loading the XAP file (it shows the percentages).

Then, the window content just goes white.

How can I debug that? How can I get an error message to know what's the cause of the error?

Does Lightswitch write some log, or can I configure it to do so?

I only have the binaries. I can re-configure and re-zip the XAP file, but I cannot re-compile the code or execute the code in Visual Studio.

Here's my config: Windows Server 2012 x64, SQL Server 2008 Express x64.

Answer 1

Solved it. I needed to install WCF HTTP Activation for some component of LightSwitch to work.

Just go to Server Manager, Add Features, then click through until you're at the feature page, then select HTTP Activation in the .NET 3.5 or .NET 4.5 nodes.
