* When consuming a portable class library depending on `HttpClient` from a
Windows Store application, the app can crash with a `MissingMethodException` .
We’ blog post about Microsoft.Bcl.Async ](http://blogs.msdn.com/b/bclteam/archive/2013/04/17/microsoft-bcl-async-is-now-stable.aspx ):
we ensure during the build that the application has a reference to the NuGet
package.
* Installing `HttpClient` NuGet package into an application can corrupt existing
binding redirects in the app.config file
* The encoding ISO-8859-1 isn’
* When using `HttpClient` in Silverlight over the browser networking stack
aborting the HTTP connection can result in a `NullReferenceException`
* Header values containing commas get incorrectly split into multiple headers.
* `HttpClientHandler.AllowAutoRedirect` can’
it should be supported.
* `HttpWebRequest.AllowReadStreamBuffering` defaults to true on Windows Phone
which prevents practical use of `HttpClient` with chunked responses, such as
streaming live data.

* First release of the portable version of `HttpClient`
## Troubleshooting
### ~~Issue 1~~
Fixed.
### ~~Issue 2~~
Fixed.
### Issue 3
#### Symptom
When using HttpClient from a Silverlight application many http headers are not
supported and will result in an `ArgumentException` or `NotImplementedException`
when set and calling `HttpClient` methods that send a request.
#### Resolution
For a list of headers which are not supported in Silverlight please see:
http://msdn.microsoft.com/en-us/library/system.net.webheadercollection(v=vs.95).aspx
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers(v=vs.95).aspx
### Issue 4
#### Symptom
When `HttpClientHandler.SupportsProtocolVersion()` is `false` the
`HttpResponseMessage` returned from a request will have a `null` value for
`Version` .
#### Resolution
Make sure that anytime you are using a version from the `HttpResponseMessage` ,
you do a null check on it if `SupportsProtocolVersion()` is `false` .
### ~~Issue 5~~
Fixed.
### Issue 6
#### Symptom
When using `HttpClient` on Silverlight or the Phone be aware that the networking
stack may cache responses.
#### Resolution
To avoid inconsistencies when creating portable class library that runs on both
platforms be sure that your server sets the cache control-header on the response
to match your expected caching behavior on the Phone. If you do not control the
server, consider making a portion of the request unique if you do not want a
cached result.
### ~~Issue 7~~
Fixed.
### Issue 8
#### Symptom
ClickOnce applications targeting .NET Framework 4.0 that reference the
`Microsoft.Net.Http` package may experience a `TypeLoadException` or other
errors after being installed.
#### Resolution
This occurs because ClickOnce fails to deploy certain required assemblies. As a
workaround, do the following:
1. Right-click on the project and choose Add Existing Item
2. Browse to the `net40` in the `HttpClient` package folder
3. In the File name text box enter *.*
4. Holding CTRL, select `System.Net.Http.dll` and `System.Net.Http.Primitives.dll`
5. Click the down-arrow next to the **Add** button and choose **Add as Link**
6. In **Solution Explorer** , holding CTRL select `System.Net.Http.dll` and `System.Net.Http.WebRequest.dll`
7. Right-click the selection, choose **Properties** and change **Copy to Output Directory** to **Copy always**
8. Republish
