Runtime Changes for Migration from. NET Framework 4. 5. Introduction. Runtime changes affect all apps that are running under a. NET Framework it was not compiled against and that use a particular feature. In the topics that describe runtime changes, we have classified individual items by their expected impact, as follows Major. This is a significant change that affects a large number of apps or that requires substantial modification of code. UtwVJ.jpg' alt='Cannot Install Net Framework 4 Windows 7' title='Cannot Install Net Framework 4 Windows 7' />Minor. This is a change that affects a small number of apps or that requires minor modification of code. Edge case. This is a change that affects apps under very specific scenarios that are not common. Transparent. This is a change that has no noticeable effect on the apps developer or user. The app should not require modification because of this change. If you are migrating from the. NET Framework 4. 5. ASP. NETASP. NET MVC now escapes spaces in strings passed in via route parameters. Details. In order to conform to RFC 2. So, whereas controlleractionsome data would previously match the route controlleractiondata and provide some data as the data parameter, it will now provide some2. Suggestion. Code should be updated to unescape string parameters from a route. If the original URI is needed, it can be accessed with the Request. Uri. Original. String API. Scope. Minor. Version. Type. Runtime. Affected APIs. Analyzers. Grid. Views with Allow. Custom. Paging set to true may fire the Page. Index. Changing event when leaving the final page of the view. Details. A bug in the. NET Framework 4. 5 causes Page. Index. Changing to sometimes not fire for Grid. Views that have enabled Allow. Custom. Paging. Suggestion. This issue has been fixed in the. NET Framework 4. 6 and may be addressed by upgrading to that version of the. NET Framework. As a work around, the app can do an explicit Bind. Grid on any PageLoad that would hit these conditions the Grid. Cannot Install Net Framework 4 Windows 7' title='Cannot Install Net Framework 4 Windows 7' />View is on the last page and Last. Page. Size is different from Page. Size. Alternatively, the app can be modified to allow paging instead of custom paging, as that scenario does not demonstrate the problem. Scope. Minor. Version. Type.

The view state message authentication code MAC is now enforced for all requests with embedded view state. Only apps that explicitly set the Enable. View. State. Mac property to false are affected. Suggestion. Enable. View. State. Mac 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. Scope. Major. Version. If you are facing issues installing. NET Framework 3. 5 many applications actually need this to run in your Windows 10 and all the other op. If you have an application that you want to run on Windows Server 2012 that requires the. NET Framework 3. 5, you will most likely run in to a problem when trying to. Today, we are announcing the general availability of the. NET Framework 4. 7. The. NET Framework 4. Windows 10 Creators Update a.

Net MVC4 apps can lead to Fatal Execution Engine Error. Details. Profilers using NGEN Profile assemblies may crash profiled ASP. NET MVC4 applications on startup with a Fatal Execution Engine ExceptionSuggestion. This issue is fixed in the. NET Framework 4. 5. Alternatively, the profiler may avoid this issue by specifying CORPRFDISABLEALLNGENIMAGES in its event mask. Scope. Edge. Version. Type. Runtime. Core. A Concurrent. Dictionary serialized in. NET 4. 5 with Net. Data. Contract. Serializer cannot be deserialized by. NET 4. 5. 1 or 4. Cannot Install Net Framework 4 Windows 7' title='Cannot Install Net Framework 4 Windows 7' />Details. Due to internal changes to the type, Concurrent. Dictionarylt TKey,TValue objects that are serialized with the. NET Framework 4. 5 using the Net. Lemmings Game Downloads more. Data. Contract.

Similarly, all 4. NET Framework 4. 6. Serializing and deserializing with a single version of the. NET Framework is not affected. Suggestion. If it is necessary to serialize and deserialize a Concurrent. Dictionarylt TKey,TValue between the. NET Framework 4. 5 and. NET Framework 4. 5. Data. Contract. Serializer or Binary. Formatter serializer should be used instead of the Net. Data. Contract. Serializer. Alternatively, because this issue is addressed in the.

Base is no longer randomized by Use. Randomized. String. Hash. Algorithm. Details. Prior to the. NET Framework 4. Dynamic. Base would be randomized between application domains, or between processes, if Use. Randomized. String. Hash. Algorithm was enabled in the apps config file. Beginning in the. NET Framework 4. 6, Dynamic. Base will return a stable result between different instances of an app running, and between different app domains. Dynamic bases will still differ for different apps this change only removes the random naming element for different instances of the same app. Suggestion. Be aware that enabling Use. Randomized. String. Hash. Algorithm will not result in Dynamic. Base being randomized. If a random base is needed, it must be produced in your apps code rather than via this API. Scope. Edge. Version. Type. Runtime. Affected APIs. Calling Attribute. Get. Custom. Attributes on an indexer property no longer throws Ambiguous. Match. Exception if the ambiguity can be resolved by indexs type. Details. Prior to the. NET Framework 4. 6, calling Get. Custom. Attributes on an indexer property which differed from another property only by the type of the index would result in an Ambiguous. Match. Exception. Beginning in the. NET Framework 4. 6, the propertys attributes will be correctly returned. Suggestion. Be aware that Get. Custom. Attributes will work more frequently now. If an app was previously relying on the Ambiguous. Match. Exception, reflection should now be used to explicitly look for multiple indexers, instead. Scope. Edge. Version. Type. Runtime.
