Record the process of upgrading the. NET Core 1.x App and the. NET Standard 1.x project to version 2.0 and encountering NuGet dependencies Today I'm going to put a long, motionless app with. NET Core 1.0.4 and the library that he relies on is written in. NET Standard 1.6 and upgraded to version 2.0 The process of upgrading also encountered some problems on the way, recorded here I have a visual Studio 2017

Beta 1 to Beta 2 Changes Here's the thing I would do if you are a developer of. NET 1. BOOKMARK this page! It'll save you a ton of the time as you migrate your apps. Then as a broken namespace in your app, or something else this no longer works in Beta2, click one of the links b Elow and search the page (ctrl-f for IE users) for your term. These documents are are part of the downloads found at www.asp.net.

Learning XML Today encountered this problem, Internet access to data analysis, the main reason for this problem is that the XML file is declared in the XML file itself when the encoding is inconsistent. For example, your statement is"1.0" encoding="UTF-8"?> However, it is saved in ANSI format, although it does not appear garbled, but the XML parser is unresolved.The workaround is to reset the encoding and declaration of the XML file when it is saved.Com.sun.org.apache.xerces.internal.impl.io.Mal

to the underlying database, but instead manipulate persisted objects in an object-oriented manner, while the ORM framework translates these object-oriented operations into the underlying SQL operations.The only function of the ORM tool is to convert the persisted object to the operation of the database by saving, deleting, modifying and so on. From then on, programmers can manipulate persisted objects in an object-oriented manner, while the ORM Framework is responsible for translating the corre

With regard to the problem, there are two related server options. execSp_serveroption@server='cia-sh-svr-sis',@optname='RPC',@optvalue='true' execSp_serveroption@server='cia-sh-svr-sis',@optname='RPC out',@optvalue='true' There are usually two ways to fetch data from the linked server. The first is access with a full path, that is, select*From[Server].[Database].sys.objects 。 The other is with the exec (The first approach seems to be unaffected by the two RPC options above, at leas

This problem is mainly to study the programming logic, we must distinguish the odd number of empty bottles and even several empty bottles, as well as the conditions to terminate the cycle. int main () { int _bottle = 0;//Empty bottle is an odd number, which means the remaining bottle int money =; int count = 0;//Total soda number int bottle=0;//empty bottle number if (Money > 0) { count = money; Bottle = money; } while (bottle!=

Original address: http://blog.csdn.net/yaerfeng/article/details/7387871 Java Hibernate object I have a problem today. Rather distressed. The requirements are as follows: There are 2 objects with the same ID, but their values are different. The property value of one of the objects to use for another object. 2 objects with the same ID cannot be present in the Sessionfactory (). GetSession of Hibernate. So come up with a copy of the object. Looking for a lot of places, found that there are 2 ways

Variables are the amount of changes. The core is the word 'change' and 'quantity'. changes are both changing, and the amount is a measure of the state. How to define variables? Variable

Speaking of greedy algorithms, we cannot avoid comparison with DP, so we need to know about the previous DP. Greedy algorithms make the selection seem to be the best at present, and we hope to generate a global optimal solution through the local optimal selection. Like summary DP in the previous chapter, I will first give an example of the easiest way to get started, to see if Shenma is greedy? (This algorithm is human-friendly. =. =) A simple example: Some backpack problems: There are N items,
