If you are migrating from the. NET Framework 4. Beginning in the. Although this will typically make apps more reliable, there are edge cases in which an app needs to know that the connection was lost so that it can take some action upon reconnection.

If this feature is undesirable due to compatibility concerns, it can be disabled by setting the System. ConnectRetryCount property of a connection string or System. SqlConnectionStringBuilder to 0. For applications that target. InputAttributes and CheckBox. LabelAttributes that are programmatically added to a WebForms CheckBox control are lost after postback. For the correct behavior for restoring attributes on postback, set the targetFrameworkVersion to 4. In applications that target. NET might incorrectly parse multipart boundary values, resulting in form data being unavailable during request execution.

Applications that target. Starting with applications running on. When targeting previous framework versions or not using targetFrameworkVersion , trailing delimiters for some values are still returned. In order to conform to RFC , spaces in route paths are now escaped when populating action parameters from a route.

Code should be updated to unescape string parameters from a route. OriginalString API. ValidationAttribute , the ValidationContext. MemberName property returns null. Starting with. Add the following setting to your web. Beginning in. HttpRequest s’ bodies. Data for applications that depend on incoming UTF-7 data will not decode properly in some cases.

Ideally, applications should be updated to not use UTF-7 encoding in System. HttpRequest s. Alternatively, legacy behavior can be restored by using the aspnet:AllowUtf7RequestContentEncoding attribute of the appSettings element. Starting with the. NET appSettings element in your configuration file.

NET browser capabilities file, so it should not be used in a custom capabilities file. If iPad-specific capabilities are required, it is necessary to modify iPad behavior by setting capabilities on the pre-defined gateway refID “IPad” instead of by generating a new “IPad” ID by user agent matching.

The view state message authentication code MAC is now enforced for all requests with embedded view state. Only apps that explicitly set the EnableViewStateMac property to false are affected. EnableViewStateMac must be assumed to be true, and any resulting MAC errors must be resolved as explained in this guidance , which contains multiple resolutions depending on the specifics of what is causing MAC errors. The LoadComplete event no longer causes the System.

This change eliminates an extraneous trip to the database, prevents the values of controls from being reset, and produces behavior that is consistent with other data controls, such as System.

SqlDataSource and System. This change produces different behavior in the unlikely event that applications rely on invoking data binding in the LoadComplete event. If there is a need for databinding, manually invoke databind in an event that is earlier in the post-back. When enabling System. StateServer session state, all of the servers in the given web farm must use the same version of the. NET Framework in order for state to be properly shared. By default, decoding methods no longer decode an invalid input sequence into an invalid UTF string.

Instead, they return the original input. The change in decoder output should matter only if you store binary data instead of UTF data in strings. To explicitly control this behavior, set the aspnet:AllowRelaxedUnicodeDecoding attribute of the appSettings element to true to enable legacy behavior or to false to enable the current behavior.

In the. With this change the SafeArray is now marshalled successfully. When using a WinRT event with a. In previous versions of the. If enabling the QI for IAgileObject breaks execution, you can disable this code by setting the following configuration. This might be just a single console session, or it might affect the entire machine if you set the environment variable globally. The environment variable name is not case-sensitive. Method 2: Registry Using Registry Editor regedit.

EXE tool to add this value from a command-line or scripting environment. The registry value name is not case-sensitive. In System. The behavior will change only when all of the following are true: The URI has the scheme file: and is followed by four or more slashes. The host name begins with an underscore or other non-reserved symbol.

The URI contains Unicode characters. Applications working with URIs consistently containing Unicode could have conceivably used this behavior to disallow references to UNC shares. Those applications should use IsUnc instead. Prior to the. Dynamic bases will still differ for different apps; this change only removes the random naming element for different instances of the same app. If a random base is needed, it must be produced in your app’s code rather than via this API.

If an assembly of compiled regular expressions is built with the. NET Framework 4, attempting to use one of the regular expressions in that assembly on a system with. NET Framework 4 installed throws an exception. To work around this problem, you can do either of the following: Build the assembly that contains the regular expressions with the.

Use an interpreted regular expression. This change makes it possible to work with collections when one of the collections is either empty or completed, but the other collection still has items that can be retrieved.

If TryTakeFromAny returning -1 or TakeFromAny throwing were used for control-flow purposes in cases of a blocking collection being completed, such code should now be changed to use. IsCompleted to detect that condition. Be aware that GetCustomAttribute s will work more frequently now. If an app was previously relying on the System. AmbiguousMatchException , reflection should now be used to explicitly look for multiple indexers, instead.

WaitAll behavior was made more consistent in. NET Framework 4, these methods behaved inconsistently. When the time-out expired, if one or more tasks were completed or canceled before the method call, the method threw an System.

AggregateException exception. When the time-out expired, if no tasks were completed or canceled before the method call, but one or more tasks entered these states after the method call, the method returned false. AggregateException exception only if an input task was cancelled regardless of whether it was before or after the method call and no other tasks are still running. If an System.

AggregateException was being caught as a means of detecting a task that was cancelled prior to the WaitAll call being invoked, that code should instead do the same detection via the IsCanceled property for example:. IsCanceled since. A new CodeDOM feature allows a compiler to compile against the targeted version of mscorlib. In some cases, when an app uses two or more app domains with different application bases, trying to deserialize objects in the logical call context across app domains throws an exception.

EventListener truncates strings with embedded nulls. Null characters are not supported by the System. EventSource class. The change only affects apps that use System. EventListener to read System. EventSource data in process and that use null characters as delimiters. EventSource data should be updated, if possible, to not use embedded null characters.

The runtime now enforces the contract that specifies the following: A class derived from System. An System. EventListener reads System.
