@Nick Actually the second call is actually being made. You can try assigning the instance to a var and printing it out, which works. The issue, as Jan and Alex pointed out, is the lack of a config file for the AppDomain, but it is only checked once. Specifying any config file (even a non-existent one) will get rid of the error. But as xUnit is the one setting up the AppDomain in the original example, I don't think that is very useful information. This does seem like a bug, though, since specifying a non-existent file can make the exception go away...

Hi, If you blame for machine.config, you might be correct because I see that: when creating the instance of AppDomainSetup with not empty ConfigurationFile, the console is working well.

My bet is second one isn't making it past the compiler since the obj is never used. Also the error says you have an Illegal char in your config. Probably the new international section that specifies how to use Unicode in the URL. Check

@timoconell Wow...I just debugged into the class and it is extraordinarily huge! I never thought that making a Uri is that complicated...

@Alex Simkin Thanks for the follow up. You answered my question. Interesting that System.Uri dissambles to over 6000 lines!

Now it is easy to explain why it works for the second time. private static void InitializeUriConfig() { if (!s_ConfigInitialized) { lock(InitializeLock) { if (!s_ConfigInitialized) { // Set this first to avoid possible recursion // if GetConfig's callees use Uri methods. s_ConfigInitialized = true; GetConfig(ref s_IdnScope, ref s_IriParsing); } } } } It only tries to parse config once.

Jan's comment sparked an interesting hunt. Could it be that you have IRI (International Resource Identifier) turned on in the machine.config? In the help file for the Uri class, it mentions that doing so prompts the Uri class to check your config for whether or not to parse using IDN (Internationalized Domain Name) rules. If it is expecting to find the config element and *isn't* that could account for finding a null during the ParseConfigFile call reference by Jan.

I got only this error: + $exception {"Invalid URI: The Authority/Host could not be parsed."} System.Exception {System.UriFormatException}

It has nothing to do with the Uri itself. With reflector you can see it tries to parse the app config file: ParseConfigFile(Path.Combine(Path.Combine(runtimeDirectory, "Config"), "machine.config"), out config, out config3); ParseConfigFile(appConfigFile, out config2, out config4); So there seems to be an error in the config file, or in the path to the config file?

Yep. Works for me too. So, what's the exception?

Works here... but what's the exception?

timoconnell , Then why would it work the second time around? And this is a console app

Matthijs, Nope. And even if there was, why wouldn't it work on the second time around?

A : (%3A) is forbidden in an URI in ASP.NET up to 3.5. In ASP.NET 4.0 you can allow it with some settings in web.config (forgot the name).

* Is this really System.Uri, or possibly another class Uri in another namespace? * check the bytes of the uristring , is there maybe something that LOOKS like a :, /, & or = but really is some weird Unicode character? * What is the Exception? * Maybe use Reflector Pro, set a breakpoint on System.Uri.InitializeUri and check what exactly this does to your Uri?

only thing I can think of is a race condition where uriString changes after the exception was already thrown.

Maybe, NET or IIS doesn't allow colons in urls [stackoverflow.com/.../using-a-colon-in-a-url-wi...](http://stackoverflow.com/questions/667429/using-a-colon-in-a-url-with-asp-net-iis)
