+
+## Troubleshooting
+
+### Issue 1
+
+#### Symptom
+
+You may get the following error when trying to add a reference to the Microsoft.Bcl.Async package:
+
+    Attempting to resolve dependency 'Microsoft.Bcl (= 1.0.0-beta)'.
+    Successfully installed 'Microsoft.Bcl 1.0.10-beta'.
+    Successfully installed 'Microsoft.Bcl.Async 1.0.10-beta'.
+    Successfully uninstalled 'Microsoft.Bcl 1.0.10-beta'.
+    Install failed. Rolling back...
+    Could not install package 'Microsoft.Bcl 1.0.10-beta'.
+    You are trying to install this package into a project that targets '.NETPortable,Version=v4.0,Profile=Profile4',
+    but the package does not contain any assembly references or content files that are compatible with that framework.
+    For more information, contact the package author.
+
+#### Resolution
+
+This happens when trying to reference a NuGet package from a Portable Class
+Library that supports platforms not supported by the package. For
+`Microsoft.Bcl.Async`, this usually occurs when trying to reference it from a
+Portable Class Library which supports Windows Phone 7.0. To resolve this, change
+the Portable Class Library to target Windows Phone 7.5 and higher.
+
+### Issue 2
+
+#### Symptom
+
+After installing the `Microsoft.Bcl` or `Microsoft.Bcl.Async` packages to
+certain projects, you may get build errors or warnings similar to:
+
+    Cannot await 'System.Threading.Tasks.Task'.
+
+-or-
+
+    The primary reference "Microsoft.Threading.Tasks" could not be resolved because it has an indirect dependency on the framework assembly "System.Runtime, Version=1.5.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "Microsoft.Threading.Tasks" or retarget your application to a framework version which contains "System.Runtime, Version=1.5.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
+
+#### Resolution
+
+`Microsoft.Bcl.Async` package is not supported in Visual Basic Web Application
+projects. As a workaround, place all async/await usage in a class library and
+consume that from the Web Application project.
+
+Otherwise, for other project types add an `App.Config` to the project with the
+following contents, replacing [version] with the version (for example,
+`2.5.10.0`) of `System.Runtime` and `System.Threading.Tasks` that you are
+referencing:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<configuration>
+  <runtime>
+    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
+      <dependentAssembly>
+        <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
+        <bindingRedirect oldVersion="0.0.0.0-[version]" newVersion="[version]" />
+      </dependentAssembly>
+      <dependentAssembly>
+        <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
+        <bindingRedirect oldVersion="0.0.0.0-[version]" newVersion="[version]" />
+      </dependentAssembly>
+    </assemblyBinding>
+  </runtime>
+</configuration>
+```
+
+### Issue 3
+
+#### Symptom
+
+After retargeting a .NET Framework, Portable or Windows Phone project from an
+older target framework version to a newer target framework version, you may get
+build warnings similar to:
+
+    The predefined type 'System.Runtime.CompilerServices.AsyncStateMachineAttribute' is defined in multiple assemblies in the global alias; using definition from 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\mscorlib.dll'
+
+#### Resolution
+
+Higher versions of these platforms already include the types from the
+`Microsoft.Bcl` and `Microsoft.Bcl.Async` packages. Uninstall them from the
+project, and remove the `<assemblyBinding>` elements from any `app.config` that
+refers to `System.Runtime` and `System.Threading.Tasks`.
+
+### Issue 4
+
+#### Symptom
+
+You get syntax errors when you attempt to use the Microsoft.Bcl.Async package in
+a web site project, similar to:
+
+    The type or namespace name 'async' could not be found (are you missing a using directive or an assembly reference?)
+
+-or-
+
+    The type or namespace name 'await' could not be found (are you missing a using directive or an assembly reference?)
+
+#### Solution
+
+`Microsoft.Bcl.Async` package is not supported in Web Sites. As a workaround,
+place all async/await usage in a class library and consume that from the Web Site.
+
+### Issue 5
+
+#### Symptoms
+
+When using the NuGet package restore feature the code doesn’t build with the
+following error message:
+
+    The imported project "<ProjectPath>\packages\Microsoft.Bcl.Build.<version>\tools\Microsoft.Bcl.Build.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
+
+#### Solution
+
+Package Restore is a feature of NuGet that will download any missing packages as
+part of the build, which means the packages folder doesn’t need to be checked
+into source control. However, this doesn’t work for NuGet packages that inject
+MSBuild targets files. You will need to make sure all *.targets files under the
+packages folder are being checked into version control.
+
+For `Microsoft.Bcl.Build` you need check in the following file:
+
+    Microsoft.Bcl.Build.<version>\tools\Microsoft.Bcl.Build.targets
+
+### Issue 6
+
+#### Symptoms
+
+When adding the NuGet package to a project that is consumed by another project
+with a different target framework you might see warnings similar to the
+following:
+
+    The primary reference "Microsoft.Threading.Tasks, Version=1.0.12.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Runtime, Version=2.5.19.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.5". To resolve this problem, either remove the reference "Microsoft.Threading.Tasks, Version=1.0.12.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Runtime, Version=2.5.19.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
+    The primary reference "Microsoft.Threading.Tasks.Extensions, Version=1.0.12.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Runtime, Version=2.5.19.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.5". To resolve this problem, either remove the reference "Microsoft.Threading.Tasks.Extensions, Version=1.0.12.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Runtime, Version=2.5.19.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
+
+#### Solution
+
+The problem is that NuGet added incorrect binding redirects for platform
+assemblies. To remove them, please open the `app.config` for the project that
+caused the warnings and remove the highlighted entries:
+
+```xml
+<?xmlversion="1.0"encoding="utf-8"?>
+<configuration>
+  <runtime>
+    <assemblyBindingxmlns="urn:schemas-microsoft-com:asm.v1">
+      <dependentAssembly>
+        <assemblyIdentityname="System.Runtime"publicKeyToken="b03f5f7f11d50a3a"culture="neutral" />
+        <bindingRedirectoldVersion="0.0.0.0-2.5.19.0"newVersion="2.5.19.0" />
+      </dependentAssembly>
+      <dependentAssembly>
+        <assemblyIdentityname="System.Threading.Tasks"publicKeyToken="b03f5f7f11d50a3a"culture="neutral" />
+        <bindingRedirectoldVersion="0.0.0.0-2.5.19.0"newVersion="2.5.19.0" />
+      </dependentAssembly>
+    </assemblyBinding>
+  </runtime>
+</configuration>
+```
+
+### Issue 7
+
+#### Symptoms
+
+When building a Windows Runtime Component (.winmd) you might get one of the following error messages:
+
+    Could not resolve reference 'Assembly(Name=System.Threading.Tasks, Version=1.5.11.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a)'.
+    Could not resolve reference 'Assembly(Name=System.Threading.Tasks, Version=2.5.11.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a)'.
+
+Please note the version number that it mentions.
+
+#### Solution
+
+This is an issue with the tool that creates a Windows Runtime Component
+(WINMDEXP). Until we address this issue you will need to work around this by
+adding a reference to the assembly directly by following these steps:
+
+1. Unload the Windows Runtime Component project by right click the project node
+   in Solution Explorer and selecting Unload Project.
+2. Edit the project by right clicking it again in Solution Explorer and
+   selecting Edit `<Project Name>`.
+3. Jump to end of the file (after the imports). Depending on the version number
+   of the error message paste in one of the following snippets before the
+   closing `</Project>` element.
+
+Version 1.5.x:
+
+```xml
+<Target Name="InjectAsyncDependencies" BeforeTargets="ExportWindowsMDFile">
+  <ItemGroup>
+    <ReferencePath Include="..\packages\Microsoft.Bcl.1.0.19\lib\sl4\System.Threading.Tasks.dll" />
+  </ItemGroup>
+</Target>
+```
+
+Version 2.5.x:
+
+```xml
+<Target Name="InjectAsyncDependencies" BeforeTargets="ExportWindowsMDFile">
+  <ItemGroup>
+    <ReferencePath Include="..\packages\Microsoft.Bcl.1.0.19\lib\net40\System.Threading.Tasks.dll" />
+  </ItemGroup>
+</Target>
+```
+
+### Issue 8
+
+#### Symptom
+
+When targeting .NET 4 you get the following error:
+
+    Could not load file or assembly 'System.Core, Version=2.0.5.0
+
+#### Resolution
+
+Using `Microsoft.Bcl.Async` on .NET 4 requires http://support.microsoft.com/kb/2468871 to be installed.
+
+### Issue 9
+
+#### Symptom
+
+ClickOnce applications targeting .NET Framework 4.0 that reference the
+`Microsoft.`Bcl or `Microsoft.Bcl.Async` packages 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 folde `net40` within the `Microsoft.Bcl` package folder
+3. In the File name text box enter `*.*`
+4. Holding CTRL, select `System.Runtime.dll` and `System.Threading.Tasks.dll`
+5. Click the down-arrow next to the Add button and choose Add as Link
+6. In Solution Explorer, holding CTRL select `System.Runtime.dll` and `System.Threading.Taks.dll`
+7. Right-click the selection, choose Properties and change **Copy to Output Directory** to **Copy always**
+8. Republish

+* Initial Release
+
+## Troubleshooting
+
+### Issue 1
+
+#### Symptom
+
+When building a phone application you get the following error:
+
+    Phone Application: Project must install NuGet package Microsoft.Bcl.Compression.
+
+After adding the reference to `Microsoft.Bcl.Compression` and rebuilding your
+app, a new MSBuild task (which comes with the NuGet package) will deploy CPU-
+specific binaries as dependencies of your app. If your app is configured as Any
+CPU, the build will fail again with this error message:
+
+    Phone Application: Microsoft.Bcl.Compression does not support the currently selected platform of 'AnyCPU'. The supported platforms are 'x86' and 'ARM'.
+
+##### Resolution
+
+The project should build successfully after you change the platform target to
+`X86` or `ARM`.
+
+### Issue 2
+
+#### Symptom
+
+When creating large ZIP files, the resulting archive is corrupted and can't be
+read by either the ZipArchive class nor by any other 3rd party compression tool.
+
+#### Resolution
+
+The problem occurs due to a bug in `ZipArchive`. Whenever the sized of the
+compressed data exceeds 4GB the very next entry that is written will cause to
+overwrite existing data.
+
+The workaround is to avoid creating ZIP files where the compressed data exceeds
+4GB. You can achieve this by compressing multiple ZIP files instead.
+
+This problem exists on the following platforms:
+
+* .NET Framework 4.5
+* .NET for Windows Store apps
+* Windows Phone 8

+
+* [Announcement](http://blogs.msdn.com/b/dotnet/archive/2013/05/22/portable-httpclient-is-now-available-as-rc.aspx)
+* When consuming a portable class library depending on `HttpClient` from a
+  Windows Store application, the app can crash with a `MissingMethodException`.
+  We’ve fixed it by using the same technique we explained in our [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’t supported on Silverlight-based platforms
+* 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’t be set on Windows Phone 8 although
+  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.
+
+### 2.1.3 Beta (Microsoft.Net.Http)
+
+* [Announcement](http://blogs.msdn.com/b/bclteam/archive/2013/02/18/portable-httpclient-for-net-framework-and-windows-phone.aspx)
+* 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
