NuGet.Common Ambient correlation ID used to associate information pertaining to a current activity. A single activity engages multiple method calls at different layers. Sometimes it's necessary to identify separate calls belonging to the same activity if shared state is needed. Returns current activity correlation ID or a default if not set previously. Starts a new activity activity correlation ID by updating ambient context value.

This enum is used to quantify NuGet error and warning codes. Format - NUxyzw where NU is the prefix indicating NuGet and xyzw is a 4 digit code Numbers - xyzw x - 'x' is the largest digit and should be used to quantify a set of errors. For example 1yzw are set of restore related errors and no other code path should use the range 1000 to 1999 for errors or warnings. y - 'y' is the second largest digit and should be used for sub sections withing a broad category. For example 12zw cvould be http related errors. Further 'y' = 0-4 should be used for errors and 'y' = 5-9 should be warnings. zw - 'zw' are the least two digit. These could be used for different errors or warnings within the broad categories set by digits 'xy'.

Log an exception to an ILogger. This will log using NU1000 if the exception does not contain a code. A class that allows one thread at a time synchronization, but is fine grained per key. For example, the key can be a resource name that must only be accessed one at a time, but different resources can be accessed concurrently. The dictionary that contains a for each key. Both reading and modifying this dictionary must be synchronized though . A lock to synchronize reading and modifying . Nested class to hold the state of per-key locks. The synchronization object used to ensure only 1 thread at a time can obtain the key's lock. A counter of how many threads/tasks have interest in the key's lock. When this reaches zero, it means no more threads or tasks want access to the resource, and the dictionary can clear its memory of the key and this state. Determines whether the full exception (including stack trace) should be displayed to the user. In prerelease or dogfooding scenarios, it is useful to have a non-verbose logging level but, in the case of an unhandled exception, print the full exception for bug reporting. True if the exception stack should be displayed to the user. False, otherwise. Fetch all of the errors logged so far. This method is useful when error log messages should be redisplayed after the initial log message is emitted. A generic interface for logging. Call legacy Log* methods from LogAsync/Log. This is for legacy ILogger implementations, new loggers should use LoggerBase. True if the message meets the verbosity level. True if the message is an error or warning.

Examples: - "a $b$ c" is parsed into {text, "a "}, {variable, "b"}, {text, " c"}. - "a $$b$$ c" is parsed into {text, "a $b$ c"}. - "a $b$ $c" is parsed into {text, "a "}, {variable, "b"}, {text, " $c"}. - "a $b$$c$" is parsed into {text, "a "}, {variable, "b"}, {variable, "c"}. - "a $b c$d$" is parsed into {text, "a $b c"}, {variable, "d"} (because space is not a word character). Gets the next token. The parsed token. Or null if no more tokens are available.

Creates an instance of with safe settings A set of . Provides a resource pool that enables reusing instances of instances. Renting and returning buffers with an can increase performance in situations where instances are created and destroyed frequently, resulting in significant memory pressure on the garbage collector. This class is thread-safe. All members may be used by multiple threads concurrently. Retrieves a shared instance. Retrieves a that is at least the requested length. The minimum capacity of the needed. A that is at least in length. This buffer is loaned to the caller and should be returned to the same pool via so that it may be reused in subsequent usage of . It is not a fatal error to not return a rented string builder, but failure to do so may lead to decreased application performance, as the pool may need to create a new instance to replace the one lost. Returns to the pool an array that was previously obtained via on the same instance, returning the built string. The previously obtained from to return to the pool. Once a has been returned to the pool, the caller gives up all ownership of the instance and must not use it. The reference returned from a given call to must only be returned via once. The default may hold onto the returned instance in order to rent it again, or it may release the returned instance if it's determined that the pool already has enough instances stored.
