While preparing my phone app for release, I thought I\'d change the version numbers on all my assemblies.

I also had an issue with the WCF service client not auto-ge

Answer 1

By renaming your Namespace your Project properties lost the Startup Object.

Just check in Project / "Project Name" Properties / Application => Startup Object, it is very likely empty.

Scroll down and select the new Namespace.Class type for the Startup.

Hope it helps.

Answer 2

Last week I got the same strange bug.

After creating a new solution (which builded and runned without problems) I discovered that changing the namespace caused the bug.

Hope it helps.

Answer 3

I post here as reference, as it took me some hours to fix this: I had the same problem, i had to go in Assembly.cs file, then make make sure that the following element has empty value:

[assembly: AssemblyCulture("")]

Putting a culture info there (eg. "en-US") makes the app quit silently on startup, without any exception nor log info.

No problem in leaving culture information in the following field:

[assembly: NeutralResourcesLanguageAttribute("en-US")]

Answer 4

Take a look at your .csproj file. In my case, everything was correct but in that file there was a reference to the old name of the project like <SilverlightAppEntry>TheOldNamespace.App</SilverlightAppEntry> So i just changed that to the new namespace name and now it works again ;)
