Code contracts - Rewriter fails with missing reference

∥☆過路亽.° 提交于 2019-12-24 02:08:01
问题 I'm trying to use code contracts for some libraries I have. My library A has a reference to ThirdParty library B. Library C references A, and never uses B nor does it use the bits of A that use B. The rewriter fails though trying to find library B. The reference assembly for A exists, I was hoping that the rewriter would be just happy with that. Any ideas on how I can build this, short of moving the bits in A that rely on B out into its own assembly? EDIT: To answer a question, yes, there are

ccrewrite fails on the build machine due to nuget references having contract assemblies

橙三吉。 提交于 2019-12-24 01:54:35
问题 Here is the whole context: I build two nuget packages containing A.nupkg: A.dll, A.Contracts.dll B.nupkg: B.dll, B.Contracts.dll; B depends on A I create a new project and solution C depending on A and B, and set "Contract Reference Assembly" to Build. Locally, everything compiles just fine. However, on the build server (MSBuild 2012.2), an exception is thrown from ccrewrite, saying ccrewrite : error : Rewrite aborted due to metadata errors. Check output window . Setting the logging to

CodeContracts issue

时光总嘲笑我的痴心妄想 提交于 2019-12-23 13:15:45
问题 Hello I have a little issue regarding CodeContracts. I have a class library project which as a class with a method foo(string s1, string s2); inside the foo method, I have a Contract.Requires(s1 != null). So if I understand the meaning of my code (yes, I just installed CodeContracts and playing with :), the contract will check the s1 != null expression during build process and in runtime, throwing ArgumentException>. I wanted to test the behavior, when I call foo(null, "test") from class lib

Code Contracts - nice, on the edge, but not ready for prime time?

孤者浪人 提交于 2019-12-23 07:58:12
问题 I got really captivated by code contracts introduced in .NET 4 (though with the help of DevLabs). But one fine print cooled me off quite a bit. Here is what it says: There is currently no workaround the problem when postconditions are called outside of lock in a thread-safe method except for not using them. .NET relies on a binary rewriter thus making the build slower. Using code contracts may also incur a runtime performance hit. Can't be used for security-sensitive checks because they can

Is there a code contract library for JavaScript? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . There are lots of form validation libraries and jQuery plugins. Though I cannot find a code contract library, for validating function arguments. As an example, to do contract validation in .NET, you could use the outstanding Conditions library. I'm looking for something similar for JavaScript. The closest I can

Microsoft Code Contracts: Error “CodeContracts: Diagnostic: Failed to connect to any cache.”

有些话、适合烂在心里 提交于 2019-12-22 04:28:53
问题 I get the following error when running Microsoft Code Contracts: CodeContracts: Diagnostic: Failed to connect to any cache. 回答1: The user manual for Code Contracts states: Cache results: Controls if the analysis results are cached. If checked, the analysis tries to avoid analyzing methods whose outcomes cannot possibly change (because no contracts, no code, and no relevant metdata has changed). Enabling this option allows for faster turn-around times if using the static checker repeatedly. To

Code Contracts for mono?

老子叫甜甜 提交于 2019-12-21 09:12:08
问题 Does mono support Code Contracts? I.e. if I build a class library, can mono users use my assembly? If not, are there any alternative libraries? Preferably supporting static analysis (through a plugin or similar in visual studio) 回答1: According to the compatability website, Monos Code Contracts API is done but the tooling is not yet complete. EDIT : The newest version of Mono (2.8) only supports Contract.Requires calls and you have to rewrite you code with ccrewrite, link. 来源: https:/

.NET exception caught is unexpectedly null

假如想象 提交于 2019-12-20 11:06:52
问题 See below for an explanation of what is going on I have a really weird issue where the exception caught is null. The code uses MEF and tries hard to report composition errors. Using the debugger I can see the exception being thrown (an InvalidOperationException ) but when it is caught by the last catch block in the code below the ex variable is null. This is true both in the debugger and when executing the code normally. static T ResolveWithErrorHandling<T>() where T : class { try {

What is a practical usage of Code Contracts in .NET 4.0?

倾然丶 夕夏残阳落幕 提交于 2019-12-20 10:19:04
问题 In order to fully understand and take advantage of the new features and enhancements provided with the coming of the new .NET Framework 4.0, I would like to get an example of real-world application of Code Contracts. Anyone has a good example of application of this feature? I would like to get a code sample with a brief explanation to help me get up and running with it. 回答1: From The Code Contracts User Manual: Contracts allow you to express preconditions, postconditions and object invariants
