History

Support for Enum by Ref 5.5.3

1. Contributed support for Enum by ref parameters.

Bug Fix for Important Edge Case 5.5.2

1. Contributed fix to case service on a host with same interface was called previously on a different host.

Replaces BinaryFormatter with System.Text.Json 5.5.0

1. Replaces BinaryFormatter in DefaultSerializer with System.Text.Json. Improves performance and reduces allocations in serializing small object graphs which is the most common use case in any RPC library.
2. Fixes null value in string array bug #50.
3. See source for former DefaultSerializer in ServiceWire.Serializers in BinaryFormatterSerializer. Use that code as a custom injected serializer if this version breaks your serialization.
4. Using ServiceWire in an ASP.NET app no longer requires the use of the EnableUnsafeBinaryFormatterSerialization flag in your project file.

Capture serialization error bug fix in 5.4.2

1. Single target of NetStandard 2.0 for a smaller NuGet package.
2. Fix to a NamedPipes performance issue.
3. Elimination of NET462 code differences.

Capture serialization error bug fix in 5.4.1

1. In .NET 5+, the BinaryFormatter is marked obsolete and prohibited in ASP.NET apps.
2. This bug caused an end of stream error rather than capturing it properly. This version fixes that bug and exposes the limitation introduced in .NET 5+ on ASP.NET apps.
3. Using ServiceWire in an ASP.NET app is still possible but requires the use of the EnableUnsafeBinaryFormatterSerialization flag in your project file. Use this carefully and be sure you understand the risks.

ICompression added for injecting compression strategy in 5.4.0

1. Added ICompression for injecting custom compression into usage.
2. Added .NET 5.0 as target back in.

AssemblyQualified names from user defined types in 5.3.6

1. Fix for AssemblyQualified names from user defined types.

Multiple Framework Targets and void Return Types 5.3.5

1. Updated all projects to target .net462, .net48, netcoreapp3.1, and net6.0 only.
2. Corrected multiple targets for multiple OS in projects for those using Linux.
3. Updated NuGet package version.

BugFix + Test cases + 48

1. Throwing the original error through an Intercept would fail for interface methods that have a void return type
2. Updated framework references from .net462 to .net48

.NET Framework to .NET Core and Serializer Bug Fixes 5.3.4

1. Support for .NET Framework to .NET Core core parameter types to eliminate exceptions when a Framework client is talking to a Core host or vice versa.
2. Serializer injection bug fixed.

.NET 4.62 added back in version 5.3.3

1. Added .NET Framework 4.62 build in package to prevent permissions issue in named pipes.
2. Fixed custom serializer issue.
3. .NET Standard 2.0 and 2.1 builds remain.
4. Resolved parallel Zk test issues.

Note: Use of async/await and Task<T> not recommended. Use of Task return type not supported. While the syntax of Task return type is supported, apparently it is not marked as Serializable. In fact async/await is not really supported. Under the covers the task type is stripped away over the wire and the method is executed on a worker thread on the server synchronously. If you think about it, you will understand that it's two separate processes, so the Task Parallel Library is not going to be able to manage the thread context across the processes. RPC is inherently synchronous but the handling of each request on the host is done on thread pools.

.NET Standard 2.0 and 2.1 in version 5.3.2

1. Changed library build to only .NET Standard 2.0 and 2.1.
2. This breaks users of named pipes in .NET 4.6.2 -- DO NOT UPGRADE until we resolve that issue.

Bug Fixes in version 5.3.1

1. Fixed bug related to complex type serialization that occurred when using output parameters.

BREAKING CHANGES in version 5.3.0

1. Injectable serialization (see project library tests for examples).

2. Removes dependency on Newtonsoft.Json and uses BinaryFormatter for default serialization which means wire data classes must be marked [Serializable].

3. Internal classes are attributed to support protobuf-net serialization as well.

Changes in version 5.2.0

1. Adds support for return types of Task and Task<T> to support async / await across the wire.

Changes including some breaking changes in version 5.1.0

1. Dropped strong named assembly.

2. Support for NetCoreApp 2.0, 2.2 and .NET Framework 4.62. Dropped support for .NET 3.5.

3. Modified projects and NuGet package generation from Visual Studio 2017.

4. Dropped separate projects used to build different targets.

5. Converted test projects to XUnit with multiple targets to allow "dotnet test" run of all targets.

Breaking Changes in version 4.0.1

1. Switched ServiceWire (and ServiceMq) to Newtonsoft.Json for serialization. Eliminates use of BinaryFormatter and its required Serializable attribute. Also eliminates ServiceStack.Text 3 dependency which has problems serializing structs.

2. Relaxed assembly version matching to allow additive changes without breaking the client or requiring an immediate client update.

3. Strong name added to allow the library to be used by strong named applications and libraries.

4. Added .NET 3.5 support to allow legacy applications to use the library. This adds a Framework specific dependency on TaskParallelLibrary 1.0.2856.0.

5. For the .NET 4.0 and 3.5 versions, changed to "Client Profile" for the target framework.

6. Removed dependency on System.Numerics in order to support .NET 3.5 and introduced ZkBigInt class taken from Scott Garland's BigInteger class. See license text for full attribution.

ConnBenchmarks (6/6/2022)

No real change from previous benchmarks. Making a connection is still expensive. About 15ms.

AllBenchmarks (6/6/2022)

These benchmarks so the improvements in switching to System.Text.Json in the CxOut tests. Faster and fewer allocations that previous benchmarks. Performance improvement is 17% on average on those specific benchmarks.
