Z3 API for .NET Core
Z3's .NET API uses Code Contracts, which are not included in .NET Core. The
enclosed file called DummyContracts.cs provides stubs for the Code Contracts
functions, so that the API will compile, but not perform any contract
checking. To build this using .NET core, run (in this directory):
dotnet restore
dotnet build core.csproj -c Release
If you are building with the cmake system, you should first
copy over files that are produced by the compiler into
this directory. You need to copy over Native.cs and Enumeration.cs
-- good luck!

The default Z3 bindings for .NET are built for the .NET framework version 4.
Should the need arise, it is also possible to build them for .NET 3.5; the
instructions are as follows:
In the project properties of Microsoft.Z3.csproj:
- Under 'Application': Change Target framework to .NET Framework 3.5
- Under 'Build': Add FRAMEWORK_LT_4 to the conditional compilation symbols
- Remove the reference to System.Numerics
- Install the NuGet Package "Microsoft Code Contracts for Net3.5":
In the Package Manager Console enter Install-Package Code.Contract
